Executive Summary

The 38 partners of EuCARD (European Coordination for Accelerator Research and

Development) are engaged in development of state-of-the-art technologies to upgrade major

particle accelerators in Europe. During the final 12 months, the project has achieved most of its

objectives and technical goals, and published some 150 scientific contributions.

WP2-DCO maintained the project web site with latest project related news, has collected over

500 publications in the publication database. As a result of an initiative over P2, we extended the

scope of the quarterly project newsletter and created a combined newsletter of 4 other projects,

enhancing their synergies. 6 issues have been published during the period and 7 additional

accelerator science monographs. WP3 (neutrino accelerator facilities) has produced reference

documents on scientific policies with respect to research infrastructures that were timely

submitted to the European HEP Strategy sessions. WP4 accelerator networks organized or co-

organized 25 well-attended workshops in various fields of accelerator sciences with concrete

outcome. Two major synthesis documents were produced, defining possible strategies for the

future of frontier accelerators and pointing to the required R&D.

The HiRadMat irradiation facility at CERN (WP5) successfully operated during the beam run

in 2012 and hosted all 7 scheduled TA experiments for data taking. 102.6 access units have been

delivered in P3. Under WP6, the TA activities continued successfully with 1107.7 access units

delivered. Principal goals of the user groups were the development of high precision diagnostics,

which proved successful.

The Joint Research Activities are the project’s backbone and enable or reinforce tight links

between European laboratories, institutes and universities, as well as two SMEs. Achievement

highlights include:

- WP7 (High Field Magnets): to mitigate the high risk of this novel Nb3Sn high field magnet

model development, additional steps have been introduced, leading to a revised calendar. The

progress accomplished gives much hope of final success: The mechanical structure of the magnet

has been completed and tested at LN2 temperature, the coil tooling has been delivered and a test

coil with Cu conductor manufactured. Nb3Sn strand for one magnet is delivered, the cable

designed, showing less than 5% degradation, well within the specification.

The HTS insert magnet components are procured and the YBCO conductor delivery expected

by September. A test coil was constructed and will be tested in September. The insert will be

finished end 2013.

The HTS link was cabled with two cabling machines and is now finished.

Two helical undulators were built and one was tested at LASA where problems indicated the

need for important design modifications.

For the support task the design and construction of all the cryostats and tooling for the irradiations

and sample tests have been completed. The irradiation of all the electrical samples and half of

the mechanical samples has been completed and some conclusions on the suitability of insulation

materials have been formulated. The thermal studies have been completed and HeII cooling

models were produced.

- WP8 (Collimation and Materials) has complemented the theoretical studies on new materials

by irradiation tests at the HiRadMat@CERN facility, with very promising results on Metal-

Diamond and Metal-Graphite composites. An important outcome of this activity has been the

creation of a multi-disciplinary collaboration, the activity of which will continue. In addition to

collimators and cryo-catchers already completed in P2 the optional test of crystal collimation

was carried out, with a measured significant increase of the particle channelling.

- WP9 (Normal Conducting Linacs) The integration challenge of the CLIC module was

exercised and its thermo-mechanical stability studied by numerical analysis and soon

experimentally after the upgrade of a dedicated test laboratory. The mechanical stabilization to

0.5 nm at 1Hz was demonstrated in an accelerator environment, validating the strategies and

equipment. The even tighter requirements for the final focus are now close to being fulfilled.

Tests in ATF2 (Japan) have allowed developing strategies and instruments for accurate beam

control; the experience gained should direct further developments to reach the accuracy required

by linear colliders. Both the electromagnetic and electro-optical phase monitors reached the goal

of an accuracy of 20 fs, suitable for the synchronization of the drive and main beams in the two-

beam accelerator concept.

- WP10 (Superconducting Radiofrequency technologies): The vertical electro-polishing setup is

completed and in use. The proton linac cavities are in the manufacturing and test process shared

between the manufacturers and the research laboratories. Delays at the manufacturers will delay

the final tests by a few months. The progress in the LHC crab cavities has exceeded the goals of

EuCARD, with the fabrication of a Nb crab cavity. The CLIC crab cavity was fabricated and the

LLRF for both developed. Good progress is achieved on magnetron sputtering, with high RRR

values, uniform films and much reduced deposition time. An EuCARD monograph was

produced on sc RF technologies, including aspects of thin films. The HOMBPM’s on the 3.8

GHz cavities was validated. Modelling and experimental studies show however that the inverse

field problem to identify cavity features from HOM signals is very difficult; nevertheless, results

obtained justify further investigations. The µTCA LLRF was finalized, installed and tested at

FLASH, already yielding a significant improvement of the field stability. Two set-ups for GaAs

cathode preparation showed contamination, and low quantum efficiency after activation. Lessons

learned allow an on-going development of a more advanced state-of-the-art preparation system.

A remarkable progress was the first FEL operation with the SRF gun at ELBE in April 2013.

The design of the automatic coupler cleaning has evolved, and the studies allow a complete

overview, including feasibility and cost.

- In WP11 (Assessment of Novel Accelerator Technologies) the final study of the crab waist

scheme applied to the LHC upgrade was completed, while additional work of the partners have

further consolidated the deliverables already provided during Period 2.

EuCARD management contributed to tightening links between leading actors in accelerator

R&D and creating sustainable European collaborations. A highlight of this activity was the

organization of the workshop “Visions for the future of accelerators”, combined with the

concluding EuCARD annual meeting and EuCARD2 kick-off meeting, attended by more than

180 experts from all around the world.

1. PUBLISHABLE SUMMARY

European Coordination for Accelerator Research and Development

The EuCARD project gathers 38 European partners engaged in state-of the-art technologies to

upgrade major research accelerators. The main components and objectives of the project are:

Networks, focused on communication and dissemination, neutrino physics facilities,

performance of hadron colliders and accelerators, and RF technologies, resulting in 40

leading laboratories worldwide being associated with EuCARD.

Transnational access facilities, offering precision beams and muon cooling setup, and pulsed

irradiation for material testing.

Joint research: 21 R&D tasks grouped under the following themes:

o Investigating the feasibility of new superconducting magnets and electrical links

using Nb3Sn and/or High Temperature Superconductors.

o Investigating the gradient limits for radiofrequency (RF) accelerating structures,

whether normal or superconducting, together with specific issues of linear colliders

such as extreme geometrical stabilization.

o Developing more robust collimators for the protection of accelerators in operational

and exceptional conditions.

o Supporting investigations on novel accelerator concepts, such as crab waist crossing,

fixed field alternating gradient and plasma wave accelerators.

The EuCARD project has fulfilled the vast majority of its

contractual goals, and in some instances of added goals

liable to reinforce the community. The TA’s have

delivered their access units, the NA’s have strongly

stimulated the community and the JRA’s fulfilled its

deliverables with few exceptions: all 63 deliverables are

delivered. One high risk deliverable gave account on the

progress made and of the planned calendar for completion

(1.5 year delay).

The number of

peered-reviewed

journal

publications

peaks during this

P3 period to reach close to one per task.

The communication network (WP2-DCO) has

regularly maintained the project website, provided

support for the Work Packages for using the Intranet and

the CDS publication database. The public website was

further developed to ensure that the JRA’s websites are

linked to the administrative and technical databases and

kept archived for the future, especially for the follow-up project, EuCARD-2. The number of

publications has reached the impressive number of 500 and over. The number of PhDs resulting

from the project has also reached 46 during the lifetime of the project and a few are still in

progress. The role of Ph.D. students’ involvement in EuCARD realization is very important and

the contributions are clearly visible in the project final achievements.

The outreach section of the website was also maintained. The quarterly project newsletter has

been replaced with the Accelerating News which extended the scope of the distribution with

more than 1000 subscribers (status on 24 July: 1046). During the period 7 additional volumes

were published under the peer-reviewed Editorial series of accelerator science monographs,

therefore reaching 18 volumes. EuCARD results and developments were reported internationally

at numerable professional conferences in Europe and outside.

The WP3-NEu2012 has finalized three strategy documents defining roadmaps for existing and

future neutrino facilities. An important event, the second EU Neutrino Strategy Workshop was

organized in May 2012, attended by more than 135 neutrino physicists, where the roadmaps were

discussed and endorsed, and submitted to the European Strategy for PP Symposium in Krakow

in July 2012. During this period, existing results came from existing facilities, reassuring the

importance of this branch of HEP, but challenges emerged for the future, with the conclusions

of the EUROnu costing report. Bringing the European and world community together becomes

even more important to face such challenges.

Over the reporting period, 25 workshops, mini-workshops and working meetings were

organized or co-organized by the accelerator networks (WP4-AccNet). Topics addressed

included quench behaviour of superconducting magnets, optics corrections, crab cavities, and

electron-cloud measurements, modeling and mitigation; design parameters for future circular

e+e- or hadron collider Higgs factories and a long-term strategy for high-energy frontier

accelerators; laser-system and FEL options for a future Higgs factory based on a recirculating

linac “SAPPHiRE”; solid-state amplifiers, low-level RF for SC linacs, and RF costing

techniques; and coordinating the plasma-

accelerators community with the purpose of

transiting from demonstrations of principle

to concrete accelerator projects. These

events have attracted world experts and

generated concrete results. A significant

number of expert exchanges have been

supported, including from non-EU

countries. Collaborations of European

accelerator institutes with the European

Space Agency and its partners, with several

Mexican institutes, and with a number of key

universities in Japan (Hiroshima, Kyoto, Tohoku) have been stimulated.

The open access facility HiRadMat@SPS (WP5-TA) successfully operated during the CERN

beam run in 2012, with 7 experiments having completed the data taking. These first experiments

included candidate materials and prototype assemblies of LHC collimators foreseen to operate

at the ultimate LHC beam powers, experiments on vacuum windows, detector calibrations and

target material options for high power proton beam applications. 102.6 access units have been

delivered in P3.

Under WP6, the TA activities continued successfully with 1107.7 access units delivered.

Principal goals of the user groups were the development of high precision diagnostics. The

performance and operation of Time-Of-Flight counters has been one of the principal goals of the

TA-supported groups from Bulgaria, Italy and Switzerland. The TOF counters have been

essential both for identification of the beam particle and for momentum measurement. Thanks

to their outstanding performance, it has proved to be possible to use these counters to measure

the momentum of single muons with a resolution of better than 4 MeV/c and systematic error of

< 3 MeV/c. Following earlier tests, the Electron Muon Ranger (EMR) detector was completed,

providing final results on the pion contamination in the muon beam. The TA has in addition

allowed fruitful exchange of information and experience among users.

WP7 (High Field Magnets): to mitigate the high risk of this novel Nb3Sn high field magnet

model development, additional steps have been introduced, leading to a revised calendar. The

mechanical structure of the magnet has been

completed and tested at LN2 temperature, the

coil tooling has been delivered and a test coil

with Cu conductor manufactured. Nb3Sn

strand for one magnet is delivered, the cable

designed, showing less than 5% degradation,

well within the specification.

The HTS insert magnet components are

procured and the YBCO conductor being

delivered. A test coil was constructed and is

being tested. The insert will be finished by end

of 2013.

For the HTS link two cabling machines were

and used. The HTS link construction is

finished.

Two helical undulators were built and one was

tested at LASA where problems indicated the

need for important design modifications.

For the support task the design and construction of all the cryostats and tooling for the irradiations

and sample tests have been completed. The irradiation of all the electrical samples and half of

the mechanical samples has been completed and conclusions on the suitability of insulation

materials have been formulated. The thermal studies have

been completed and HeII cooling models were produced.

WP8-Collimation and Materials managed to finish its main

deliverables ahead of schedule. In this reporting period the

emphasis was the investigation and characterisation of novel

materials for accelerator and collimator applications.

Previously irradiated samples where characterised.

Irradiation tests with novel materials could be done at GSI

and the HighRadMat facility established within the EuCARD

framework. The successful tests lead to the use of these

materials in test collimators for the LHC even beyond the

scope of this project.

WP9-NCLinac concerns a number of studies relevant for Linear Colliders (LC) presently

considered as future energy frontier

machines. Focused on the Compact Linear

Collider (CLIC) study it treats high-gradient

normal-conducting accelerating structures, in

particular their integration of these structures

in the so-called two-beam module and the

resulting limitations and constraints

concerning RF power and phase, breakdown,

higher-order modes, cooling, vacuum,

mechanical tolerances, alignment and

stabilisation and the overall integration. The

stabilisation and alignment question

addressed were treated using a quadrupole

mock-up, which could be successfully stabilized to the required nanometre level in a real

accelerator environment. These results are relevant for both normal-conducting and

superconducting RF based LCs. Also the solutions studied for the demanding beam diagnostics

for a beam delivery system (BPMs and LW), which were implemented and thoroughly tested at

ATF2 and PETRA3, are significant independent of the chosen technology. The exact control of

beam phase to precisions of below 0.01° (of 20 fs) is equally a problem for many future

accelerators, including linear colliders and light sources, but for large linacs it becomes even

more demanding, since phase information from very distant location has to be compared.

NCLinac has advanced this field both for the phase pick-ups as well as for the synchronisation

over long distances.

WP10 (Superconducting Radiofrequency technologies): The vertical electro-polishing setup

is completed and in use.

The proton linac cavities

are in the manufacturing

and test process shared

between the

manufacturers and the

research laboratories.

Delays at the

manufacturers will delay

the final tests by a few

months. The progress in

the LHC crab cavities has exceeded the goals of EuCARD, with the fabrication of a Nb crab

cavity. The CLIC crab cavity was fabricated and the LLRF for LHC and CLIC developed. Good

progress is achieved on magnetron sputtering, with high RRR values, uniform films and much

reduced deposition time. An EuCARD monograph was produced on sc RF technologies,

including aspects of thin films. The HOMBPM’s on the 3.8 GHz cavities was validated.

Modelling and experimental studies show however that, while the beam position can be

accurately extracted, the inverse field problem to identify cavity features from HOM signals is

very difficult; nevertheless, results obtained justify further investigations. The µTCA LLRF was

finalized, installed and tested at FLASH, already yielding a significant improvement of the field

stability. Two set-ups for GaAs cathode preparation showed contamination, and low quantum

efficiency after activation. Lessons learned allow an on-going development of a more advanced

state-of-the-art preparation system. A remarkable progress was the first FEL operation with the

SRF gun at ELBE in April 2013. The design of the automatic coupler cleaning has evolved, and

the studies allow a complete overview, including feasibility and cost.

WP11-ANAC (Assessment of Novel Accelerator Technologies) has provided its last

deliverable: a new concept for the LHC luminosity upgrade, based on flat beams, large Piwinski

angle and crab-waist, inspired by the DAΦNE upgrade, has been shown, quite unexpectedly, to

open new strategies to reach the goal of the LHC upgrade. This new approach requires further

studies to increase the particle stability. Non-

EuCARD work continuing the other tasks of

WP11 (DAΦNE, EMMA and emittance of

beams accelerated by laser-plasma) has further

consolidated the already provided EuCARD

deliverables.

EuCARD

management, beyond running the project, has continued its contribution to tightening links in

the accelerator community and creating sustainable collaborations. The concluding project

meeting was associated to a EuCARD workshop on visions for the future of accelerators and to

the kick-off meeting of EuCARD2, thereby drawing perspective for the immediate and farther

futures.

2. CORE OF THE REPORT FOR THE PERIOD: PROJECT OBJECTIVES, WORK PROGRESS AND ACHIEVEMENTS, PROJECT MANAGEMENT

2.1 PROJECT OBJECTIVES FOR THE PERIOD

In this final period of the project, the contractual objectives include the largest fraction of the

deliverables, as most tasks have the full project duration, while some shorter tasks were late. The

number of milestones naturally decreases, and many are lumped with their corresponding

deliverables.

The management (WP1) objectives have been mainly two-fold: i) create optimal conditions to

favour a successful termination both for the S/T studies and for a major reporting exercise: the

P3 periodic report (D1.3), over 40 deliverable reports for review at a learned journal level and

the final report (D1.4); ii) keep the momentum of the collaboration by attractive project events:

the third annual meeting (M1.4) and a conclusive meeting analysing the results and offering

perspectives (M1.5).

With a series of ambitious communication tools put in place in Periods 1 and 2 (web site,

publication portal, newsletters and monographs), the goals of the dissemination,

communication and outreach network (WP2) are to consolidate them and organize their

transmission to either TIARA or EuCARD2. Presentations on communication aspects, achieved

efficiency and future plans were the goals of the status reviews in two Annual Meetings (MS4,

MS5), with in view the final report summarizing the strategies and results (D2.1.1). The

deliverable foreseen on the use and dissemination of foreground turns out to be strictly redundant

with a chapter of the final report and will refer to it (D2.2.2).

The main goals of the scientific networks (WP3 and WP4) during this period are to finalize and

complete their activities: for WP3, this period is a key with the organization of

meetings/workshops in view of the production of three strategy documents that must meet the

consensus of the community: D3.1.2, D3.2.1 and D3.3.1 and serve as input to the update of the

European HEP strategy. For WP4 AccNet, the goal has been to actively continue the activities

of the three networks (M4.1.4, M4.2.4, M4.3.4) and prepare important deliverables summarizing

the network activities and results, putting forward the specific added value produced (D4.1.2,

D4.2.2, D4.3.3).

Two facilities are open to Trans-National access: the HiRadMat@CERN (WP5) started open

access in the second part of P2, continuing through the largest part of P3. As to MICE@STFC

(WP6), which already had fulfilled its contractual obligation, the goal was to continue the open

access thanks to savings on EC resources and support from the STFC.

For most JRA tasks (WP7-11), the goal of task 1 of each WP has been to follow-up progress,

favouring technical exchanges by WP meetings, review meetings, or coordinator visits.

Reporting is an important aspect of these tasks. A number of milestones were attached to these

activities: M7.1.3&4, M8.1.3&4, M9.1.3&4, M10.1.3&4, except for WP11 that essentially

reached completion.

For WP7 (High Field Magnets), an essential goal is to reassess, with the support of its advisory

committee, the HFM program, schedule and take the steps to organize its full completion planned

after the EuCARD termination. All deliverables related to the model (studies and prototype) are

to be delivered: D7.2.1, D7.2.2, D7.2.3 and D7.3.1 . The WP will conclude as well on the HTS

insert fabrication (D7.4.1), on the construction of a 20m HTS link (D7.5.1) and on a prototype

of a Nb3Sn helical undulator (D7.6.1).

WP8 (Collimation and Materials) being ahead of schedule, it main goal in this period is the

documentation of a CERN deliverable (D8.3.1), and of the WP8 activity.

In WP9 (Normal Conducting Linacs), all milestones were met and the period objective is the

delivery of deliverables all scheduled for the project end (D9.1.1, D9.2.1, D9.2.2, D9.3.1, D9.3.2,

D9.4.1, D9.4.2, D9.5.1, D9.5.2). These deliverables include key aspects of the CLIC collider and

of common issues for ILC and CLIC colliders (RF cavities, geometric stabilization, ultrafast

synchronization, handling of very low emittance beams).

WP10 (Superconducting RF) is the largest WP in terms of number of tasks and deliverables,

funding and spectrum of research topics. Most of its milestones were met in the preceding period,

and all its deliverables except one are to be delivered during P3: D10.1.1 (data handling); D10.2.1

(super-conducting elliptical proton cavities); D10.3.1&2&3 (LHC and CLIC crab cavities,

LLRF for both); D10.4.2&3&4 (aspects of thin film cavities); D10.5.1&2 (use of HOM signals

as beam and cavity diagnostics; D10.6.1 (advanced LLRF for FLASH); D10.7.2 (higher yield

photocathodes); D10.8.1 (automated coupler processing).

WP11 (Assessment of Novel Accelerator Concepts): All other objectives having been met in

Period 2, the only deliverable remaining is D11.2.2.

These objectives of Annex 1 have been complemented by additional objectives in the interest of

the project and to consolidate the accelerator R&D community. They are discussed in the

description of the work progress and the management results.

1.1.1. WP1: Project management

Please refer to Section 2.3.

1.1.2. WP2: Dissemination, Communication and Outreach (DCO)

The mandate of the Dissemination, Communication and Outreach (DCO) Work Package is to

establish and maintain efficient communication inside the consortium and enhance the

dissemination and outreach outside the consortium towards the scientific community and

beyond. The WP includes two tasks:

Task WP2.1: Coordination and communication,

Task WP2.2: Dissemination and Outreach

1.1.2.1. Task WP2.1: DCO Coordination and communication

Progress towards objectives

The main objectives have been to ensure an effective flow of information within all the Work

Packages, between WP2 and the Management and throughout the whole project. In this period

the DCO team organized 3 face-to-face meetings and 1 video meetings of the DCO team.

The DCO deputy coordinator is also an active member of project coordination meetings in order

to report DCO matters to WP1 Project Management. A network of WP DCO liaisons was

continued, to maintain a clear, two-way communication channel between WP2 and other WPs.

Synergies with other related accelerator projects were further developed and formalized in

Period 3 with the launch of the joined newsletter, Accelerating News1. Due to the newsletter,

EuCARD DCO team has combined efforts with TIARA, HiLumi LHC, EUROnu and CRISP.

For further details, see Section 1.1.7

Contractual milestones and deliverables

The deliverables due in this period (D2.2. and D2.3) have been achieved. The M9 milestone due

in this period has also been achieved.

Policy events and surveys

The Project Coordinator and administrative manager attended several meetings with EC officials

to discuss project related accelerator R&D topics, strategy in Horizon2020. The Coordinator also

attended and represented the project at the International Conference on Research Infrastructure

(ICRI 2012) conference. He also contributed to the “Consultation on possible topics for future

activities for integrating and opening existing national research infrastructures” issued by the EC

and initiated a coherent response from various branches of the community. The assessment of

this survey2 (published in February 2013) placed the topic of Accelerator R&D in a prominent

position.

Accelerating News (formerly EuCARD Newsletter)

During the period, the EuCARD newsletter was replaced by the Accelerating News, a

collaborative newsletter aimed at the accelerator community. The Accelerating News - first issue

was published on 24 April 2012- is a combined newsletter taking advantage of the synergies

formed between EuCARD and other accelerator projects cofunded by EC FP7. Four projects

were initially part of the newsletter: EuCARD, HiLumi LHC, TIARA and EUROnu. When the

EUROnu project finished in September 2012, the CRISP project was added to the newsletter.

The scope of the Accelerating News was extended over P3: it now covers a larger variety of

fields and targets a wider audience, also in some cases covering accelerator related topics from

life sciences. The number of subscribers rose from 800 to 1046, attesting to the success of the

new format of the newsletter. In order to further improve the Accelerating News, a survey3 was

conducted online and it received positive answers. The newsletter was also used to advertise the

EuCARD monographs, which led to a dramatic increase in orders from all around the world. The

Accelerating news will be continued under TIARA-PP and EuCARD2.

EuCARD-related Doctorates

46 Ph.D. theses were identified as associated to EuCARD during the whole duration of the

project. The WP leaders were made aware that the Ph.D. theses may be published as EuCARD

booklets. A number of Ph.D. theses related to EuCARD were published in the Monograph Series.

Due to different formal regulations concerning doctorate promotion processes at the European

universities, not all of the relevant theses were published in the Series. They were however

published by the relevant university press. Many of the project related theses are not yet finished.

They will be continued with EuCARD2.

EuCARD publication portal

A user-friendly publication portal is in operation. It has a customized interface of the existing

CERN Documentation System: the publications can be browsed against the type, kind, source

and work package. It automatically handles the needs of the refereeing system, depending on the

type of publication. As of 30 August 2013, the publications logged in the database amount to –

numbers in upper row of the table, but the increase in these numbers for P3 period are shown in

the lower row:

the project. The management of EuCARD continuously favours open access publications and

journals.

EuCARD Monographs

Seven additional EuCARD monographs have been published in Period P3 (reaching 18 volumes

in total). The monographs are also publicly available via the CDS database. Before distributing

to the partner libraries worldwide, IP and copyright issues have been investigated properly.

During the final Annual Meeting of EuCARD and kick-off meeting of EuCARD-2 the editor had

many discussions with the Conference participants concerning the support of this action, and the

interest in this sort of fast but strictly peer reviewed, and nicely printed publications, with ISBN

number. The series will be continued and the relevant discussion will also be continued within

the EuCARD2. The editor sent a few copies of full sets of these monographs to science and

technology financial decision makers with a very positive, even surprisingly positive, response.

A few meetings at the Nat. Ministry of Science and Education, and Ministry of Infrastructure

followed, with possible infrastructural consequences in the future.

DCO coordinator sent out approximately 250 copies of the monographs, separately from the

numbers of copies managed by CERN. These were sent to local libraries at around 20 universities

and the rest went to individual researchers.

1.1.3. WP3: Structuring the accelerator neutrino community (NEu2012)

NEu2012 offers a platform for consolidating the European neutrino community and enhancing

collaborative work and exchanges in view of delivering at the end of 2012 an agreed programme

of neutrino experiments, based on upgrades of existing infrastructures and/or on the proposal of

a new one. WP3 includes 3 tasks:

Task WP3.1: Coordination and communication

Task WP3.2: Getting the most out of existing neutrino facilities

Task WP3.3: Roadmap to the next European accelerator neutrino facility

1.1.3.1. Task WP3.1: Coordination and Communication


The coordination of the WP activity continued by steering meetings and by frequent contacts

among coordinators. They focused on the successful organization of the third annual meeting of

the network (ie the 2nd EU Neutrino Strategy Workshop in May 2012) and on the effort to

assemble its last final road map deliverables.

Discussions with managers of projects closely related to NEu2012 (LAGUNA-LBNO, EUROnu,

IDS-NF as always and now CENF, ESS neutrinos and more) became even more frequent. The

program committee of the Strategy Workshop represents indeed all these components. This

included recently participation to the last EUROnu meeting June 2012, the most recent

LAGUNA meeting in Desy Feb 2013, the most recent IDS-NuFact meeting in RAL Apr 2013

and to the meetings of emerging proposals as NuSTORM (late March 2013) and of an ESS

powered neutrino Superbeam (May 2013).

Dissemination for WP3 remained an important area of work. WP3 steering committee members

were present in many international workshops with plenary and parallel talks confirming the

international visibility of NEU2012 and of the neutrino activities in Europe. The coordinators

were all on the program committee of the international NuFact12 workshop.

Monitoring developments in our research sector also remained very important. The sin213

reactor results in China, Korea and France in Spring 2012 confirmed the hope that CP violation

measurements were possible and called for. They are possible only with long baseline accelerator

neutrino experiments, more than ever a vibrant sector, in spite of all our EU difficulties, those

encountered in US for the approval of the Fermilab project (LBNE) or expected in Japan for their

new T2HK enterprise.


The M48 milestone (fourth and last WP3 annual meeting) was cancelled, after all WP

deliverables were produced (D3.1.2, D3.2.1 and D3.3.1). Convening the community appeared to

be more appropriate in autumn 2013 after the final formulation of the HEP Strategy and a better

definition of its impact on the community.

1.1.3.2. Task WP3.2: getting the most out of existing neutrino facilities


During the reference period the CNGS neutrino beam facility at CERN had its final year of

operation. The facility successfully concluded a cycle of seven years of operation since its start-

up in 2006. In the end 1.8×1020 protons were delivered on target, corresponding to about 80% of

the estimated beam intensity in the approved program. At the same time, the Grand Sasso

experiments advanced in their analysis and the OPERA collaboration announced the discovery

of two more ντ appearance events, thus making three in total, compatible with the expectations.

In the graph below the evolution of the integrated beam intensity for CNGS is shown.

Date: 15/10/2013


In 2012, a lot of studies, specific instrumentation and measurements were done to better

understand the timing structure of the beam, such to undoubtedly resolve any issue or source on

the CERN side of errors that may contribute to the miscalculation of the beam timing.

The experience gained by the operation of this high-intensity beam facility over the seven years

from 2006 to 2012 is a very important asset for CERN and Europe. Supported by Neu2012

meetings and discussions occurred in 2012 to prepare the input for the European Neutrino

Community to the Strategy Upgrade Process. The submitted papers included both physics

experiments and schemes for possible upgrade of the CERN accelerator complex towards a next

generation neutrino beams.

In particular, the possibility to provide a higher-intensity proton beam up to 750 kW was outlined

as well as the required R&D program to achieve it. The table below indicates the SPS potential

to provide CNGS-type beam for neutrino facilities after implementation of the LiU upgrades.

The detailed studies are on-going within the LAGUNA-LBNO EU/FP7 Design Study,

addressing SPS but also its injectors in particular PS.

Two scientific proposals were submitted to the SPSC in 2012. The first, from the LBNO

collaboration, describing a staged approach for a CERN-based long-baseline neutrino beam from

CERN to a far detector located at the Pyhasalmi mine in Finland at 2300 km distance. The second

is a combined proposal from the ICARUS and NESSiE collaborations for the study in a short

baseline in the North Area with detectors at 460 and 1600 m distance.

As starting stage for this new generation of beams, the concept of a Neutrino Test Facility in the

SPS North Area is considered to create a neutrino detector R&D area where detector prototypes

could be exposed simultaneously to a neutrino beam and low-energy charged beams of (e, u, û).

The physics reach and performance of the facilities has been the subject of several meetings

organized within EUCARD/Neu2012 and summarized in a one-day workshop organized at

CERN and in the Task 3 report.

1.1.4. WP4: Accelerator Science Networks (AccNet)

AccNet is the project platform for exchange, investigations and assessment of accelerator

upgrades, technologies and new infrastructures. It includes three tasks:


Task WP4.2: EuroLumi network (accelerator performance)

Task WP4.3: RFTech network (RF technologies)

Task WP4.4 EuroNNAc (novel accelerators) : new additional network since 2010.

1.1.4.1. Task WP4.1: Coordination and communication


At the 12th meeting of the EuCARD Steering Committee on 6 December 2012 the status and

plans of AccNet were reported. Since summer of 2012 AccNet-EuroLumi launched and

supported studies on various novel types of Higgs factories, such as circular e+e- colliders (LEP3,

TLEP), collider, a high-luminosity ep collider based on the LHC, as well as higher-energy

hadron colliders (HE-LHC, VHE-LHC), either in the LHC tunnel and in a new 80-100 km tunnel.

Presentations featuring and disseminating results of AccNet studies were given at various

occasions during this period, e.g. at invited seminars at Oxford, KEK, Frascati, Saclay, Orsay,

Sendai, CHIPP, oPAC workshop.

In total 25 AccNet mini-workshops and AccNet co-sponsored conferences were organized, e.g.

on LEP3 and TLEP (5 mini-workshops), on VHE-LHC, on SAPPHiRE, on electron cloud, on

LHC optics, on LLRF for X-FEL, on the use of C for industry and research, and low-level

RF for XFE, and on advanced acceleration concepts.

The AccNet web site was continually updated and enhanced. Budget and manpower plans were

also updated and adjusted.


The final annual AccNet steering committee (M4.1.4) was held during the parallel sessions of

the EuCARD13 Annual Meeting. The AccNet Strategy for future proton & electron facilities in

Europe (deliverable D4.1.2) was published in the form of a report.

1.1.4.2. Task WP4.2: EUROLUMI


The topical workshops were organized by EuroLumi either alone or in collaboration with EU

and non EU partners wherever relevant. Amongst important EuroLumi partners from outside

Europe are the consortium of US national accelerator laboratories US-LARP, the KEK

accelerator laboratory and Hiroshima University in Japan, and CINVESTAV Mexico. The goal

of the topical workshops typically was to assemble 30 to 40 world experts for brainstorming on

advanced topics. In most cases, the attendance exceeded this goal, demonstrating the added value

of this format of networking. In all workshops, the fraction of participants originating from

outside EuCARD was significant, typically 25%, sometimes above 50%. Events were often

organized at CERN in view of its numerous facilities, lower costs and easy air flight connections

to most world destinations, and since the main topic of EuroLumi – the LHC upgrade – is directly

linked to CERN.

Workshop 3, attended by the CERN Director of Accelerators & Technology as well as by the

KEK “trustee” in charge of strategy, was the first ever workshop discussing the possibility of a

circular Higgs factory in the LHC tunnel or in a new 80 or 100 km tunnel. It was followed by

four similar mini-workshops in 3-month rhythm (workshops 4, 6, 10 and 14), making rapid

progress on the accelerator design. Workshop 8 was the first ever event devoted to a low-cost

Higgs factory, and workshop 9 the first one devoted to 100-TeV pp collider in a new large tunnel.

Together these workshops developed a cost-efficient staged strategy towards delivering highest-

energy highest-luminosity collisions of various species to study the Higgs boson with the best

possible precision and to explore the closure of the standard model and to discover New Physics.

Workshops 1, 5, 7, 11, and 13 addressed important aspects of the HL-LHC design, the LHC

injector upgrade, and FAIR. Workshop 12 (“EuCARD13”) on the visions for the future of

accelerators was co-organized by WP4 EuroLumi. One example outcome of these workshops

was the stronger collaboration with the European space satellite community assembled around

ESA. Another was a novel technique of electron cloud diagnostics, developed by the CERN-GSI

collaboration in the framework of EuroLumi, by which the average electron cloud density around

a storage ring is inferred from the bunch-by-bunch synchronous phase shift. The ratio of

registrants/speakers is included to illustrate the dynamic interactivity. For comparison, at a

typical IPAC this ratio is ~12.

These workshops provided excellent opportunities to share experience among several fields of

RF technology, from low-level systems to solid-state power amplifiers.

More specifically, the 4th RFTech workshop covered a large range of RF topics, including C-

band RF, X-band RF, reliability, LLRF, RF diagnostics, reliability, costing, breakdown,

operation, klystron lifetime, and RF efficiency; and it also addressed RF issues for many

important present or planned accelerator facilities, e.g. SPIRAL2, MYRRHA/MAX, CLIC,

TESLA, ELI-NP, LHeC ERL, TLEP, LHC, FLASH, PS Booster, MedAustron, and SwissFEL.

Participants came from DESY, CERN, INF-INFN, TUD, UROS, GANIL, PSI, LPSC/CNRS,

UJF, TUL, and ISE-WUT.

RFTech also organized or co-organized several topical workshops related to low-level RF

control, as well as special sessions at the MixDes2012 Conference on Mixed Design for

Integrated Circuits and Systems with applications to accelerator RF systems, and at the ICAP’13

on accelerator RF related computing. Some RFTech experts also attended the IEEE Conference

workshop on Real Time techniques, RT2012, in June 2012.

An important result is a report on strategy/results for cavity design, LLRF & HPRF systems and

design integration, and costing tools.

1.1.4.4. Task WP4.4: EURONNAC

EuroNNAc – a European Network for Novel Accelerators looking at the Next Generation of

Novel Electron Accelerators – was launched in December 2010 on the EuCARD initiative.


The second major EuroNNAc workshop was held at CERN, on 2-4 May 2013. It created four

task forces towards an EU-wide (or even global) coordination of advanced accelerators, defined

strategies and detailed plans for each task force, progressed towards a coherent proposal of one

or a few European and international pilot facilities for advanced accelerators; prepared a written

report on novel acceleration and the EuroNNAc network; approved plans for a European

conference for advanced accelerators (the first one EAAC2013), and prepared an input statement

to European Strategy for Particle Physics ("On the Prospect and Vision of Ultra-High Gradient

Plasma Accelerators for High Energy Physics").

EuroNNAc organized the first ever EAAC workshop, in Italy from 2 to 7 June 2013, with 145

participants. An important practical conclusion is that a substantial extra funding is to be found

to accomplish the EuroNNAc goal of a distributed European test facility.


The new network fulfilled in the past period all of its voluntary milestones and deliverables.

1.1.5. WP5: Transnational access HiRadMat@SPS

HiRadMat (High Irradiation to Materials) is a new facility at CERN designed to provide high-

intensity pulsed beams to an irradiation area where material samples as well as accelerator

component assemblies can be tested. The facility uses a 440 GeV proton beam extracted from

the CERN SPS with a pulse length of 7.2 μsec, to maximum pulse energy of 3.4 MJ. In addition

to protons, ion beams with an energy of 173.5 GeV/nucleon and total pulse energy of 21 kJ can

be used. Over the reference period, the first HiRadMat experiments took place as scheduled and

successfully completed data taking in the beam period from May to November 2012. A detailed

list of experiments is online available at http://cern.ch/hiradmat (section experiments). These

first experiments included candidate materials and prototype assemblies of LHC collimators

foreseen to operate at the ultimate LHC beam powers, experiments on vacuum windows,

benchmarking detector and target material options for use in future high power proton beam

applications.

Figure 20: Photo of the HiRadMat experimental area. The primary beam line with its last equipment is shown on

the left. The three yellow base-supports for the experiments are visible at the centre, with one experiment already

installed in the middle one. The massive beam dump is visible downstream the beam path.

The beam conditions relevant to the experiments: intensity, pulse structure, focusing and spot

size possibilities, beam interlocks conditions etc. are defined and documented in the project web

page: http://cern.ch/hiradmat.

As HiRadMat@SPS is a high-intensity beam area substantial pre-cautions are necessary for the

access and operations with the users. For each experiment three phases are needed: a) preparatory

phase including experiment review by CERN safety officials; typically 6-9 months before the

experiment is scheduled, b) the preparation of the experimental setup outside the irradiation area

and subsequent installation using remote tooling to the area and the exposure to beam, and c) the

final removal of the equipment and inspection at the end of the experiment and some cool-down

period. TA funds were also used to cover the needs of the experimental teams in all three phases.

Table 1 lists the experiment schedule of 2012 for data taking with beam.

1.1.5.1. Description of publicity concerning new opportunities for access

Access to the HiRadMat facility has been publicised principally through web pages,

presentations at international conferences, complemented by targeted visits and emails to

potentially interesting communities and laboratories. The HiRadMat web pages, also accessible

through the EuCARD main web, give an overview and the capacity of the facility and provide

information on the rules and regulations for access. Conference presentations include workshops

on future Neutrino Facilities, high-power target development, the International Accelerator

Physics conference and EuCARD meetings. Visits to PSI and RAL laboratories have been

organized to present the facility and its potential.

1.1.5.2. Description of the selection procedures

The HiRadMat Scientific Board assesses the beam and TA requests, by inviting each team to

present the scientific goals, proposed installation and post-irradiation analysis of their

experiment. On positive recommendation by the Scientific Board a beam time slot for the

experiment on the yearly schedule is reserved. This beam slot is then validated after the

experiment is reviewed and positively recommended by the HiRadMat Technical Board

consisting of CERN beam experts and safety officials. The Scientific Board meets typically three

times per year, while the Technical Board upon needs.

Over the reference period the following board meetings took place:

23. April 2012 Scientific Board Meeting

15. June 2012 Technical Board Meeting

27. July 2012 Technical Board Meeting

28. September 2012 Technical Board Meeting

18. October 2012 Scientific and Technical Board Meeting

With the CERN accelerator shut-down beginning December 2012 until end 2014 no more

experiments are scheduled and board meetings were not required anymore.

Scientific output of TA-supported users at the facility

User meetings

Due to the special nature of the HiRadMat facility and the stringent conditions implied to the

experiments, mainly due to the induced radiation fields from the high-power beams, preparing

for experiments can be rather challenging. Therefore sharing of the information, on experimental

techniques and tooling is vital and heavily promoted to best use the TA funds. During the beam

time period until December 2012 user meetings were scheduled on a bi-weekly basis (Friday

afternoon). This was continued for a few weeks after the start of the CERN shut-down for de-

commissioning activities of the experiments.

1.1.6. WP6: Transnational access MICE

WP6 provides transnational access to a specialized beam line at the Science and Technology

Facilities Council (STFC) ISIS facility at the Rutherford Appleton Laboratory (RAL). This

beam line, together with its associated infrastructure, was originally referred to as the MICE

facility, but in order to distinguish the facility more clearly from the MICE experiment (see

below), the facility is now designated the Ionisation Cooling Test Facility (ICTF).

The ICTF provides muon beams of either sign, pulsed at 1 Hz, in the momentum range 120

MeV/c to 350 MeV/c, as well as protons, pions and electrons from 100 MeV/c to 400 MeV/c.

The intensity of the muon beam is ~50 particles per pulse. During P3 significant progress has

been made on the installations for the radio-frequency (RF) and Liquid Hydrogen (LH)

systems, which will complete the facility.

The ICTF has been developed in the first instance for the MICE experiment (Muon Ionisation

Cooling Experiment) http://mice.iit.edu/, which is the first experiment to be installed at the

facility. The MICE experiment will allow high-accuracy measurement of emittance, and will

deploy unique absorbers (using the Liquid Hydrogen) and re-acceleration stations (using the

RF) to assess the efficiency of ionization cooling.

1.1.6.1. Description of publicity concerning new opportunities for access

All available TA resources were allocated at the end of P2 (see P2 report), and so access to the

facility was not advertised further during P3.

1.1.6.2. Description of the selection procedures

As reported previously, all available TA funding was allocated just before the end of P2, so the

Selection Panel did not meet during P3.

A total of 1107.7 transnational access units (beam-hours) were used during period 3.

Scientific output of TA-supported users at the facility

TA-supported users have made wide-ranging contributions to the scientific output from the

facility during P3.

The scientific goals of MICE depend on the measurement of the beam emittance, using a single-

particle method. The Time-of-Flight (TOF) counters have been essential both for identification

of the beam particle and, prior to the availability of magnetic spectrometry in 2015, for

momentum measurement. Thanks to the outstanding performance of the TOF counters (see also

P2 report), it has proved possible to use these counters to measure the momentum of single

muons with a resolution of better than 4 MeV/c and systematic error of < 3 MeV/c. The ability

to measure the longitudinal momentum, pz , to this precision will complement the momentum

measurement of the magnetic spectrometers. For low transverse amplitude particles, the

measurement of pz in the TOF counters is expected to have better resolution than that of the

spectrometers, which are primarily designed for measuring the transverse component of the

momentum.

The performance and operation of the TOF counters has been one of the principal goals of the

TA-supported groups, in P3 as well as in P1 and P2.

Figure 21and Figure 22 (taken from http://arxiv.org/pdf/1306.1509v1.pdf) show the measured

horizontal and vertical emittances, compared to simulations. These results demonstrate that the

beam emittances are highly suitable for the MICE experiment

Further highlights during P3 have been the completion of the Electron Muon Ranger (EMR)

1.1.7.2. Task WP7.2: Support Studies


Task WP7.2 consists of two sub-tasks:

Sub-task WP7.2.1 (Radiation resistance certification for coil insulation and

impregnation): detailed specification of irradiation at LN2 temperatures, start of

irradiation of samples, determination of mechanical properties measurements, design of

the cryostat for electrical certification measurements at LN2 temperature

Sub-task WP7.2.2 (Thermal models and design): thermal measurements of the un-

irradiated samples, development of steady state and transient thermal model of the

magnet coil, determination of the safe heat load to the magnet coil, cool-down time and

cryogenic system cooling capacity.

Sub-task WP7.2.1 Radiation resistance certification for coil insulation and impregnation

A first series of irradiations at National Centre for Nuclear Research (NCBJ), Swierk, Poland on

the thermal samples was concluded in June 2012 but due to the high dose rate the samples are

not usable due to too large radiation damage. Tests were done to understand this excessive

damage and solutions were found by reducing the dose rate by a factor of two and some cooling

improvements. It was decided to re-schedule the irradiations of the samples such that the ones

with the shortest irradiation times will come first: the electrical samples first, followed by the

mechanical samples and then the thermal samples. At present the irradiation of the electrical

samples and half of the mechanical samples has been completed. The equipment for the

cryogenic electrical and mechanical characterisation tests, e.g. the cryostats, high voltage

equipment and traction equipment was designed, constructed and commissioned. The irradiated

mechanical and electrical samples and the non-radiated reference samples have all undergone

their characterisation tests. A deliverable report was produced in June 2013 and submitted in

July 2013.

Figure 23: Electrical breakdown before and after irradiation with a dose of 50 MGy of 6 MeV electrons

Sub-task WP7.2.2 Thermal models and design

The deliverable 7.2.3 “Superfluid helium transport model for the thermal design of the high field

model magnet” was produced in May 2013. This deliverable covers the work on the construction

of a new numerical finite element model using a simplified formulation of the two-phase theory

for superfluid He for accelerator magnets.

Sub-task WP7.2.1 – Radiation resistance certification for coil insulation and impregnation


Sub-task WP7.2.2 - Thermal models and design.



1.1.7.3. Task WP7.3: High Field Model


During the period, 23 meetings of the Magnet design working group were held. Furthermore an

External Scientific Advisory Committee (ESAC) review was held in February 2013.

The ESAC review committee acknowledged the progress made and the maturity of the

project. It recommended to carefully get confirmation of the validity of each step of the

construction. It insisted on the need for a test with one or two (out of 4) coils to validate

the concept of flared-end coils.

The strand procurement progressed well and at the end of the period enough strand had

been delivered to construct one full set of coils for the dipole.

The cable for the dipole was developed and the cable design is valid for both PIT and

RRP conductors, which are being procured. The degradation of the critical current due to

the cabling process is less than 5 %.

The mechanical design is complete and the magnet structural components have been

procured and delivered. The structure was assembled with dummy Al pieces in place of

the coils and extensively instrumented with strain gauges. This ‘dummy’ magnet has been

tested at liquid N2 temperature in a purpose-built installation at CERN to verify the

detailed mechanical behavior under cool-down.

Detailed models of several types have been made to calculate the quench protection cases

of the dipole. The conclusion is that the magnet can be protected with a comfortable

temperature of 140 K can be achieved in a worst-case scenario.

The test facility for the LHe test of the dipole has been designed. The outer vacuum vessel

of the cryostat has been ordered and the delivery is foreseen for summer 2013. The

tendering procedure for the inner He vessel Cryostat has been started and this component

is expected for delivery by June 2014. The cryogenic components (eg. valve boxes and

transfer lines) and the cryogenic controls racks and test instrumentation racks are in an

advanced state of detailed design and will be ready in summer 2014. The test station will

be installed in the CERN vertical tests station in building SM18 where the pit for the

cryostat, the power supply and other auxiliary equipment already exist.

A complete design report has been written. The report covers the electromagnetic and

mechanical design of the magnet, the quench protection, the tooling design, the coil

manufacturing and the assembly procedures. The design report is part of the deliverable

for this task.

A coil of the 3-4 type with Cu conductor has been wound with the final tooling. A small

modification of the reaction tooling will be implemented at the end of the summer after

which a few turn superconducting test coil will be wound and reacted to test the

procedures.

The main deliverable (7.3.1 at M48) was rescheduled as more tests and intermediate steps were

introduced to consolidate the design and manufacturing steps of the dipole magnet and due to

the delays in the construction of the test station. The deliverable report can nevertheless be

produced in 4 parts describing the main design and construction steps. This comprises of

Part I: Design report for the dipole magnet

Part II: Dipole magnet structure tested in LN2

Part III: Nb3Sn strand procured for one dipole magnet

Part IV: One test double pancake copper coil made

The magnet with a single superconducting coil will be tested in September 2014 in the new

CERN test station. The completion of the Fresca2 magnet is now part of the CERN and CEA

core activities as it is essential for the development of high field magnets for future proton

colliders and is therefore guaranteed.

1.1.7.4. Task WP7.4: Very high field insert

Progress towards objectives:

This last period was mainly devoted to finalize the mechanical design of the dipolar insert, to

finalize the drawings and to launch the orders for all tooling and mechanical part, to order the

conductor and to prepare the final tests.

The design report for the dipolar insert was produced in May 2013. It contains the

following chapters: insert magnet configuration, conductor definition, magnetic study

with the outsert, protection, mechanical structure, assembly, HTS test solenoids. The

report is the object of the deliverable D7.4.1, part I

Protection studied for the 2 magnets powered together: this point is quite important, many

simulations were done with different codes. If the protection of the insert alone is not a

problem, the problem is more crucial when the insert will be powered inside the Fresca2

dipole. It is unclear how high hot spot temperatures can be tolerated in an YBCO coil and

when does the delamination of the conductor really occur. It is expected that a lot of

information will be gained from the tests of the magnet.

Order and delivery of the conductor: the core YBCO conductor was ordered in December

2012. Its delivery is expected in September 2013, with some delay showing the technical

problems when increasing the unit length of YBCO tape

Study and ordering of mechanical parts: all the studies for the mechanical parts for the

windings and for tooling were finished in June 2013. All the orders were passed until

beginning of July. Delivery is expected until November 2013 (Deliverable D7.4.1, part

III). Realization of a prototype and preparation of its test: a single pancake prototype was

wound at Saclay in July 2013, and has been sent to Grenoble for testing in September

2013. In parallel, a test facility has been prepared to test this insert in a 10 T external field

at Grenoble. A particularity is that it will be possible to change the orientation of the

pancake in the external field to study this effect on the conductor critical current (D7.4.1,

part II).

Figure 25: Cross-section and 3D model of the insert

The protection of the HTS insert remains an issue due to the very low propagation velocities and

the high current densities. The very large magnetic coupling (0.9) with the outer Nb3Sn dipole

makes the protection more difficult. From the study of different quench scenarios we conclude

that a fast discharge of both magnets is mandatory. Another simulation work, based on finite

element codes, gives the space and thermal evolutions of the hot spot. They confirm the very

slow development of the normal zone with two consequences: the difficulty to detect a quench,

and high mechanical stresses due to differential thermal contraction. Highly instrumented coils

with different characteristics (Cu quantity, insulation) have been made to verify these

simulations.

HTS insert, interface with the Nb3Sn dipole

The design of the HTS insert dipole has been studied in detail with 3D electro-magnetic and

mechanical models. The insert will be mechanically independent from the Nb3Sn dipole. The

insert supporting structure is a 3 mm thick stainless steel tube. The magnet is composed of six

flat pancakes wound with a 12 mm wide YBCO conductor.

The conductor is made of two tapes soldered together with a Cu tape. This configuration should

meet the numerous requirements such as mechanical performance, protection, industrial

realization, AC losses etc.. A first length was produced by the tape manufacturer and will be

tested. To get a nominal insert field of 6 T insert with a current of 2800 A two conductors will

be put in parallel with transposition from pole to pole for a balanced current distribution. Central

iron poles are added to reduce the peak fields. A mock-up with dummy Al coils has been made

with the iron poles, the steel pad and the external tube. The pad is machined in two parts and will

be welded together. The external tube will be shrink-fit around the pad.

Technological implementation, First YBCO solenoids and pancakes

To proceed step-by-step towards a dipole insert of HTS conductor, several HTS solenoid coils

have been made and tested up to their limits in existing high field facilities at partner’s labs. Only

YBCO coils have been realized, as this was the chosen conductor. Tests have been carried out

and protocols have been defined to make low resistance (40 nΩcm2) and reproducible

connexions between YBCO tapes.

In Grenoble, a double pancake carried a current of 400 A at 4.2 K under 18 T before the tape

broke close from a current lead. The engineering current density was 1000 MA/m2 and the hoop

stress overstepped 700 MPa. Another double pancake was tested in Karlsruhe, and showed very

similar results: the breakdown occurred at a hoop stress of 730 MPa, but under 10 T and 700 A

.

In conclusion, after several YBCO coils made with low performance, new coils, both layer and

double pancake type, were successfully made, with a performance close to the conductor intrinsic

limits. Those are higher than the values in the designed YBCO insert.

finished test pancake coil (right).


Deliverable D7.4.1 has been delivered by the end of July 2013 describing the results obtained

and plans.



The final deliverable (7.4.1, M48) will be delayed by approximately 6 months as more tests and

intermediate steps were introduced to consolidate the design and manufacturing steps of the

1.1.7.5. Task WP7.5: High-Tc superconducting link


The superconducting link task developed and built a 20 m long Superconducting Link made of

HTS (High Temperature Superconducting). Following an intense R&D activity, which included

the study of novel concepts of cables made from HTS tape conductor and the development and

test of prototype units, the final deliverable was successfully assembled at CERN in May 2013.

A five-meter long Superconducting Link containing 25 Twisted-Pair MgB2 cables was

assembled at CERN and successfully tested at the University of Southampton. More

recently, a dedicated campaign of tests was launched at the University of Southampton

with the objective of studying the performance of the cables in case of resistive transition.

Transient behavior in He gas environment was studied.

Following the successful validation of prototype cables, two novel cabling machines

were developed and assembled at CERN. These machines enable respectively a) the

controlled production of long -kilometer length- electrically insulated stacks of tapes and

b) the final twisting and electrical insulation of two stacks of tapes to produce the final

Twisted-Pair unit. The process is applicable to MgB2, YBCO and Bi-2223 conductors

[2].

Twenty-five Twisted-Pair cables, each containing three MgB2 tapes and four copper

strips, were made at CERN using the newly developed cabling machines. The 25

Twisted-Pair cables were then assembled together to form the 20 m long final multi-cable

assembly. The multi-cable assembly was found to have the originally estimated

geometrical characteristics (about 40 mm external diameter when MgB2 tapes are used)

and a minimum-bending radius of about 1 m. Each Twisted Pair cable in the assembly is

able to transfer 2×±1 kA at 30 K and 2×±2 kA at 20 K

A 20 m long Nexans line with dimensions optimized for hosting the multi-cable assembly

was procured by CERN. A novel test station, which integrates this line has been designed,

constructed and fully commissioned at CERN

1.1.7.6. Task WP7.6: Short period helical superconducting undulator


After the selection of the Supercon Nb3Sn wire (see previous periodic report), much of the work

was devoted to the preparation, realization and tests of 2 similar 300 mm long helical undulators.

For the construction of the 2 undulators the former manufacturing steps were modified for

minimizing the risks of failure. A method to alumina- coated the former was developed and

qualified. The vacuum impregnation method was also qualified. Finally, the two undulators were

realized during Q4 2012 at STFC-RAL.

Date: 15/10/2013


The test of one undulator was done at LASA. For this an agreement was found with INFN-LASA

laboratory to test the two undulators in their laboratory during Q1 2013. The results were quite

disappointing: one undulator had a very high resistance (broken wire) and could not be tested.

The second one had quenches well below the nominal, and a resistive part was detected on it.

Nevertheless, magnetic measurements were performed at low current. The cause of these

problems was later identified as a break in the conductor. Also, the fractured macor winding

posts indicate that significant tensile force was present in the windings at some stage of the

realization.

1.1.8. WP8: Collimators and materials (ColMat)

The goal of this WP is to improve collimation efficiency by i) a better modelling of the beam

halo, ii) a selection of robust materials compatible with the ultra-high vacuum, iii) prototyping.


Task WP8.2: Modelling, materials and tests for hadron beams in LHC and FAIR

Task WP8.3: Collimator prototyping and testing for hadron beams in FAIR and LHC.



The progress of WP8 was reported in the EuCARD last annual meeting at CERN. The annual

meeting being the kick-off meeting of EuCARD² as well the results obtained in WP8 were topic

in the highlight talk “R&D on Novel Advanced Collimator Materials: Results and Perspectives”.


The last ColMat meeting (M8.1.4) was held informal in parallel to the EuCARD2013 meeting at

1.1.8.2. Task WP8.2: Modelling, materials and tests for hadron beams


The progress in the various activities is summarized:

1. The MERLIN C++ library for accelerator was improved and benchmarked against other

simulation results.

2. Theoretical studies on accidental beam impact on collimators with finite element codes

and hydrodynamics codes were performed. Experiments for benchmarking these results

have been performed at the HighRadMat facility at CERN.

3. The studies on novel metal diamond and in addition metal graphite composites were

continued very successfully by a joined effort of many WP8 participants. The material

was produced in suitable large pieces for collimators, tested for basic mechanical and

electrical properties. Samples have been irradiated and various pre- and post-irradiation

tests were performed. Copper-Diamond and Molybdenum-Graphite materials provide

very promising results. They are now used for the construction of a future full scale LHC

collimator, which will be installed in the LHC during the present upgrade. The

experimental and theoretical studies will continue till the end of EuCARD and beyond.

A large new collaboration has been formed by the ColMat efforts on Metal-Diamond and

The goal of task WP8.3 is to design and manufacture prototypes of advanced collimators and to

qualify their performance for usage with high power hadron beams in FAIR and LHC.


The goal of task WP8.3 was to design and manufacture

prototypes of advanced collimators and to qualify their

performance for usage with high power hadron beams

in FAIR and LHC. Both prototypes were produced,

tested and reported in previous reporting periods.

A bent Crystal Collimator has been manufactured at

INFN Ferrara. It was installed and tested with beam in

the SPS. A significant reduction of secondary

interaction compared to a regular absorber could be

observed proving that the primary particles where

channeled through the bent crystal planes.

1.1.9. WP9: Technology for normal conducting linear accelerators (NcLinac)

The WP focuses on major issues in high-gradient acceleration, beam stabilization, emittance

preservation and beam handling in the final focus.


Task WP9.2: Normal conducting high gradient cavities

Task WP9.3: Linac and final-focus stabilization

Task WP9.4: Beam delivery system

Task WP9.5 Drive beam phase control

1.1.9.1. Task WP9.1: Coordination and Communication


The coordination between the different tasks has been smooth and natural. Areas that required

some effort were the coordination between task 9.2, looking at the CLIC high-gradient

accelerating and decelerating structures as part of the two-beam module (TBM) with all its

aspects of mechanical precision and tolerances, cooling and temperature control, stability and

the integration into the tunnel, and task 9.3, addressing the linac alignment and in particular the

investigation possibility to align stabilize of a main beam quadrupole mock-up, which of course

is also integrated with the TBM.

The coordination and communication activities also included the organization and planning of

the annual meetings and here in particular the parallel sessions and the satellite meetings, in

which the annual reviews were performed and which gave the possibility to bring representatives

of all tasks together face to face. This was done both in Warsaw in 2012 (see

https://indico.cern.ch/conferenceTimeTable.py?confId=166908#all.detailed) and at CERN in

2013 (https://indico.cern.ch/conferenceTimeTable.py?confId=234798#all.detailed). We

reported in detail on the progress of NCLinac on these meetings, complemented by highlight

talks on selected topics (2012: “Feedback performance, precision alignment and nanometer scale

stabilization of CLIC magnets” by A. Jeremie and “CLIC RF structure precise assembly and

thermo-mechanical modeling in CLIC” by K. Österberg, 2013: “Understanding the breakdown:

new prospects?” by F. Djurabekova and “Linac stabilization” by K. Artoos). Both these meetings

were at the same time used to prepare EuCARD-2, in which parts of NCLinac will find a logical

continuation (in 2 tasks in its work package 12, “RF Technologies”). Initiated also by the

excellent results of NCLinac’s work package 9.3, a special FP7 proposal for an initial training

network on metrology and alignment was very successfully rated and has now started

(http://pacman.web.cern.ch/pacman/). The highlight talks and the contributions by the different

partners to the EuCARD Newsletter, which later became the “Accelerating News”

(http://www.acceleratingnews.eu/) was the outreach created by NCLinac.

With the coordination and communication between the tasks of WP9 well established, but also

with excellent coordination inside EuCARD as a whole and in fact with the other active FP7

instruments in the field of accelerators and accelerator physics (HiLumi-LHC, TIARA,

EuCARD-2), NCLinac brought forward the field quite significantly, reflected also in the quantity

1.1.9.2. Task WP9.2: Normal Conducting High Gradient Cavities


Double-length PETS – CIEMAT has successfully completed the design, assembly and test of

the first double-length PETS for the CLEX module. The design comprises eight identical copper

bars with damping material and two compact couplers placed at both ends of the bars to extract

the generated power. The first PETS unit was fully assembled (see Figure 31) and tested at low

power. The compact couplers were successfully brazed and electro-beam welded to the so-called

mini-tank. The geometrical control of the eight corrugated copper bars as well as of the compact

couplers was within specification. The measurements were cross-checked and confirmed at

CERN. For the RF characterisation, a dedicated system to measure the S-parameters was

developed by CIEMAT (see Figure 32 and Figure 33). The power transmission efficiency was

obtained by placing between the couplers several copper rings with different lengths

(corresponding to 0°, 60° and 120° phase advance). No significant de-tuning was observed. A

second PETS unit is currently under fabrication and planned to be completed in December 2013.

New companies have been qualified for this production.

HOM damping – The UNIMAN collaboration is focused on a linac consisting of 26-cell

structures providing a 100 MV/m accelerating field and ensuring sufficient wakefield

suppression by interleaving different structures. The design for a 6-fold interleaved structure is

complete. Following a pre-series phase validated at CERN, the production of the entire structure

has been launched at Morikawa in Japan. The dimensional control of the disks and the

preliminary RF results (see Figure 34 and Figure 35) showed that the disks were acceptable and

that the structure could be tuned to reach the specification. Indeed, only few m errors have been

observed. The assembly consisting in bonding the disk stack and brazing the couplers onto it has

been completed. The cooling circuits will be brazed in September and the RF measurements and

tuning will follow. The structure is foreseen to be tested at high power in the year 2014.

A new cell design has been studied. It features improved overall wakefield suppression and

exhibits a larger 1st dipole bandwidth. An improved HOM coupling from cell to manifolds is

also proposed together with a reduced H-Field value on the cavity walls.

Breakdown simulation – UH continues to pursue a multi-scale model to understand electrical

breakdown in accelerating structures. One of the key findings is that dislocations are activated

in the near-surface region of accelerating structures during its operation by the stress. These

dislocations can contribute strongly in nucleating of rough features, which at a later stage can be

further enhanced by long-term processes such as, for instance, surface diffusion enhanced by

electric field and electro-migration due to high field emission currents. However, the studies

show that a void buried under the surface can initiate the self-reinforcing growth of a protrusion,

if a high electric field is applied to the surface (see Figure 36). This mechanism can be seen

experimentally in the catastrophic growth of field emission currents, measured in the DC setup

at random spots on a seemingly flat surface. These features (field emitters) on a nanometre scale

may lead to breakdown events, giving a possible resolution of the long-standing mystery of

vacuum breakdowns in the absence of sharp surface features.

Figure 36: Simulation of the creation of a protrusion

from a void due to stress

Figure 37: Fits of the breakdown rate as function

of the accelerating gradient

This mechanism is confirmed by the analysis of crater features seen in the high resolution

scanning electron microscope images of spots of breakdown damage.

At a different scale, an analytical model based on thermodynamic consideration of formation of

extended defects in thermodynamic equilibrium gave a solid ground to the experimental

measurements of breakdown rates versus accelerating gradients. The experimental data could be

fitted with comparable quality to the existing empirical fits (see Figure 37), however providing

a physical interpretation to the fit parameters, such as the formation energy to create a dislocation

or void and the volume change due to this dislocation. Moreover, the prediction of this

dependence to be non-linear with decrease of the value of the gradient was confirmed later on in

the experiments conducted at CERN.

A hybrid electrodynamics/molecular dynamics model with the focus on the electronic dynamics

has been developed. The Joule heating of thin protrusions leads to the evaporation of atoms,

assisted by the applied field. This comprises a neutral component necessary for plasma

formation. The results of a 2D particle-in-cell calculations show the necessity of greater flux of

neutral atoms for the plasma to develop until a sustainable stage. The existing 2D particle-in-cell

model was refined to increase the resolution near the source of the neutrals (a tip). This led to

the result indicating the possibility of full small plasma development close to the tip; the plasma

ions sputter the surface at the early stage of full plasma build-up, feeding back the developing

plasma.

Diagnostic equipment – The upgrade program of the two-beam test stand continued with the

installation of the flashbox (see Figure 38). Signals of breakdown were recorded and analysed.

A program was developed to increase the sensitivity of the probe beam position monitors. The

piezo-motor driven stage to investigate in-situ discharges inside an electron-microscope has been

improved continuously and now permits scanning. Tests have been conducted on different

samples, which were then cut to investigate the presence of voids (see Figure 39).

Figure 38: Installation of flashbox in the two-beam test stand

Figure 39: Observed sub-surface voids

Precise assembly – UH continues the study on the high-precision assembly of RF structures and

several activities are on-going in parallel. The FE model of the two-beam module (see Figure

40) has been remarkably improved. In addition to the gravity, vacuum and RF loads, the

environment conditions (see Figure 41) have been added allowing thus to simulate the thermo-

mechanical response of the module following different ambient temperatures (from 20 ℃ to

40 ℃) and air speed (from 0.2 m/s to 0.8 m/s). The tests on the first module prototype (see Figure

40) started in January 2013. Several CLIC operation conditions have been tested by gradually

heating the different module components. In addition, by measuring the position of the fiducials

on the RF structures with the laser tracker Leica AT401, the alignment of the beam axes is also

derived. At the same time the temperature of the RF structures is monitored and recorded

throughout the tests by means of the sensors attached to them. The experimental results are in

good agreement with the model. Figure 41 shows the measured and predicted transient thermal

response of the accelerating structures by changing the ambient temperature from 20 ℃ to 30 ℃;

to be noted that the experimental transient time, almost twelve hours, is in agreement with the

results of the numerical modelling.

1.1.9.3. Task WP9.3: Stabilisation


A prototype of the final mechanical guidance housing the actuators of the CERN stiff

stabilization system (see previous periodic report for unprecedented stabilization results) further

improved the resolution of the positioning and nano-metrology and increased the lateral stiffness

by a factor 500. A final mechanical design was made for a CLIC Main Beam Quad type 1 (100

kg, 0.5 m) and type 4 (400 kg, 2 m) based on aluminium profiles and plates (Figure 44). Supports

for the alignment sensors and the interface with the alignment system were also included in the

design.

Figure 44: a) Stabilisation system MBQ type 1 b) cut-away view with inclined actuators

A test bench representative of the stabilisation system (Figure 45) was built in order to house

several means to measure the relative displacement of the test mass. This allowed a comparative

study between strain gauges in the actuators, the voltage applied to the actuators, capacitive

gauges, a triple beam LASER interferometer, a broadband seismometer and an optical linear

encoder.

For the pre-alignment system, all the upgraded cam movers were validated successfully on a 1

DOF mock-up. Repeatability below 1μm was obtained throughout the whole measurement range

of 10 mm, and below 0.3 μm was over a reduced stroke of ± 3mm.

A 5 DOF mock-up was built for the final validation of cam movers and installed in one of the

most stable places at CERN. It consists of an instrumented rigid chassis, on which additional

loads can be put, installed on 5 cam movers. A mechanical system blocks the 6th degree of

freedom, along the longitudinal Z axis (Figure 46). The following results were obtained:

Movement resolution below 1 μm everywhere in the displacement range, repeatability below 5

μm for the two translation axes (X and Y), and below 5 μrad for the roll (rotation around the Z

axis), the correct position was found in 3 to 5 iterations without additional load (more iterations

were needed when load was added), displacement accuracy depends on the length and

complexity of displacement for example displacements accuracies are in the order of 10-20 μm

and μrad for the first iteration in case of simple movements.

Figure 46: 5-DOF mock-up coordinate system

These results showed that the type 4 cam mover based system meets precision requirements

using an iterative process. A more compact cam system is currently under development for the

alignment of the Main Beam quadrupole type 1. The first compact cam mover has passed 1 DOF

tests successfully.

For the Type 1 and Type 4 Main Beam Quadrupoles, the 2nd Generation iron quadrants of the

Type1 were delivered and mechanically measured at CERN Metrology Lab. The complex pole

shapes are well inside a ± 7µm tolerance and this is an extremely good result. The 2nd Generation

Type1 MBQ is now assembled. The procurement of the quadrants for the 2nd Generation Type4

MBQ (~1800 mm length) is still undergoing, due to the difficulties in finding companies

potentially able to provide ultra-precise machining on long components. The imminent magnetic

field quality measurement results should give an indication, on how these tight achieved

tolerances translate into a “beam optics quality” point of view.

Concerning the Intra-train beam stabilisation feedback prototypes for ILC and CLIC: The

upstream coupled loop feedback system was re-commissioned and its impact on the beam near

the IP was measured. For the purpose of obtaining optimal spatial correlation between bunches

in the extracted bunch train the ATF damping ring was set up to extract 2 bunches with a

separation of 274.4 ns. The upstream system was first set up and the optimal gain was selected.

The system was then operated in an interleaved mode with the feedback applied on alternate

machine pulses With the feedback off the second bunch RMS jitter was measured to be

(3.6 ± 0.2) μm in P2, (3.7 ± 0.2) μm in P3 and (3.9 ± 0.2) μm in IPA. With feedback on the

second bunch RMS jitter was measured to be (1.3 ± 0.1) μm in P2, (1.4 ± 0.1) μm in P3 and (2.6 ± 0.1) μm in IPA. The level of correction upstream is as expected given the bunch to bunch

correlations of 94% measured with the same data. At IPA it is clear that the level of jitter

reduction seen in the upstream system does not propagate downstream fully; work is currently

on-going to improve the propagation of the jitter reduction.

Concerning the pulse-to-pulse feedback, different ground motion (GM) models have been used.

Simulations combining different controller strategies show that the GM model has an important

influence on the performance in terms of luminosity or offset. On a variety of reasonable GM

models, the scheme allows reaching an IRMS of the beam motion of about 0.2 nm @ 0.1 Hz

combined with other feedbacks leading to an average luminosity loss of less than 1.7%. Even if

some simplifications have been made concerning the transfer functions and the instrumental

resolutions, the results are well within the required performance to have enough margins when

the detailed accelerator component behaviours are known.


The due deliverables D9.3.1 and D9.3.2 were delivered.

1.1.9.4. Task WP9.4: Beam Delivery System (BDS)


Over the reporting period, the ATF2 laserwire (LW) program was completed with a

measurement of micron scale beams, resulting in uncertainties in the order of 10%; results have

been reported at IPAC2012 and IBIC2012. Outcome of this work is submitted as an article to

Phys. Rev. Special Topics, Accelerators and Beams. Also the ATF2 cavity BPM system could

be completed and is providing essential diagnostics information for ATF2, which recently

demonstrated focused beam sizes of 70 nm. The development work for advanced low-Q CBPMs

was finalized with a test of a low-Q stainless steel prototype, which showed good agreement

with RF simulations. The main developments for the LW during the reporting period were

conducted at PETRA3, where a fibre laser was used to generate laser pulses to collide with the

electron bunches. The development of this system is now complete and first measurements

completed. Two more weeks long measurement campaigns are planned before final publication

of the PETRA3 results.

Cavity Beam Position Monitors

The cavity beam position monitors (CBPM) installed at ATF2 were designed by KEK, built by

Pohang Accelerator Laboratory (South Korea) and are maintained and operated by RHUL in

collaboration with SLAC and KEK. RHUL provided the main readout and control code and

performed the operational support for the system.

Prototype cavity beam position systems (three devices) have proven position resolution at 10s of

nanometres. During the reporting period approximately 40 devices were thoroughly used and

tested at a test facility with similar features as a linear collider (LC). The experimental

methodology was elaborated and system performance studies in detail. Figure 47 shows

photographs of the installed C-band (left) and S-band CBPMs installed inside the ATF2

quadrupoles; a more detailed description is available in the deliverable report EuCARD-Del-

Laserwire scanner

Laserwires use a focused beam of laser light that interacts with the charged particle beam only

weakly to provide information on the transverse beam size. This method offers higher resolution

that classical methods, does not disrupt the beam but requires a complex high power laser system

and optical focusing.

A laserwire project was initiated at ATF/ATF2 in 2005 and over the last eight years has

progressed towards the final goal of micrometre scale beam size measurements. Royal Holloway

and the University of Oxford have constructed the entire laserwire system (apart from the laser

which was loaned from KEK). During the reporting period the laserwire has achieved its

technical goal measuring 𝟏 μ𝐦 vertical beam sizes, improving the state of the art from (𝟓 ÷ 𝟏𝟎) 𝛍𝐦 at the start of the project. Figure 48 below gives an example from a detailed

nonlinear vertical scan of an electron beam using 61 laser positions and 20 machine samples,

indicating a measurement of a beam size of 𝝈 = 𝟏. 𝟏𝟔 𝛍𝐦; for a detailed description and

Beam Phase Monitor

Prototypes of the beam phase monitor pickup have been completed and tested. Lab RF

measurements are in good agreement with simulations. In Figure 49 the simulation (plots at the

top) and measurement (bottom) results are compared. The plots on the left are the transmission

response between two of the four coaxial outputs, where the resonance of the volume between

the filters is visible. The plots on the right are the transmission between one coaxial output and

one probe placed at one pipe end. The effect of the notch filter is clearly visible. The additional

resonance at ~12.14 GHz in the bottom right plot is introduced by the measurement system and

it is due to a residual probe misalignment that produces excitation of parasitic modes in the

structure.

this arrangement, using the detection electronics, the bunch phases along the train have been

measured and the result is reported in the plot of Figure 50.

Within the reporting period the following progress has been achieved:

Two types of beam pick-ups have been characterized with beam. Other than expected the high charge

design worked also best for the low charge regime and will be used for future designs.

The optical front end, which contains the fibre-optical and the opto-mechanical components

necessary to measure the cross-correlation between the laser reference and the electron bunch, was

produced and tested. With the results obtained, a second version was designed with vastly improved

local temperature stabilization to minimize drift effects.

We built a photo receiver and data acquisition using a 12 bit ADC with 500 MS/sec sample rate.

Control and read out were implemented using Matlab scripts.

In extensive beam tests of the full system, the correlation of the drift of the system versus

environmental variables as temperature, humidity and air pressure as well as the machine

parameters as beam charge and size were studied. The obtained time resolution was 20

femtoseconds, corresponding to 0.1° at the CLIC frequency of 12 GHz, which fits well the

required specification.

1.1.10. WP10: superconducting RF Technology for proton accelerators and electron linear accelerators (SRF)

The main activities concentrate on two different areas: cavity improvements and beam

experiments. Improved methods for cavity treatment such as vertical electro-polishing or sputter

coating are investigated. Prototype work on superconducting (SC) crab-cavities is initiated with

the goal to increase the luminosity of colliders such as LHC, CLIC or ILC. The second research

activity concentrates on further developing Low Level RF techniques and on new diagnostic

tools based on the analysis of Higher Order Modes (HOM).

Task WP10.3: LHC & CLIC crab cavities

Task WP10.4: Thin film cavities

Task WP10.5: HOM distribution

Task WP10.6: LLRF at FLASH

Task WP10.7: SCRF gun at ELBE

Task WP10.8: Coupler development at LAL



The fourth SRF Annual Review took place on 25-26 and 29 May 2013 as face-to-face meetings

between the Work Package leader and Task leaders, according to the following agenda:

25 May at DESY, for Tasks 10.8, 10.3, 10.5, 10.7 and 10.6

16 May at CERN, for Tasks 10.1 and 10.4

29 May at CEA, for Task 10.2.

This review was used to finalize the agenda of the missing deliverables and preparation of the

EuCARD Final Meeting on June 6, 2013. Only three Deliverables were still missing on May

29th:

D10.2.1: the cavity RF tests are scheduled in August and September 2013. These tests

are critical milestones for CEA and CNRS in view of their contribution to ESS project.

D10.4.2: the magnetron sputtering facility at INFN-Legnaro is operational and

preliminary tests are promising. No cavity was available for the coating and the RF test.

D10.4.4: due to the transfer of its main author to the ESS AB Company and the fact that

recovering from this situation turned out not to be possible, the only option was to re-

orient the study towards materials and surface aspects in the development of SRF

niobium cavities, including the initial focus of thin film cavities. An interesting outcome

is the write-up of a EuCARD Monograph by C. Antoine (CEA) on this specific topic.

1.1.10.2. Task WP10.2: SC Cavities for proton linac


The first activity of this task has consisted in the fabrication follow-up of the two SPL type

elliptical cavities, manufactured respectively at RI and ZANON companies.

For the β=0.65 cavity, the kick-off meeting took place at RI premises in November 2011. The

manufacturing file was provided to IPN Orsay beginning of March 2012 and the official release

for fabrication was given 2 weeks after. The field flatness tuning process with the bare cavity

was originally planned in October 2012 (and delivery of the complete cavity with its tank in

February 2013) but, because mainly of the overload of the RI and subcontractors workshops, the

fabrication was delayed by more than 5 months. Several intermediate RF measurements of the

half-cells, dumbbells and end-groups have been done between January and February 2013 to

match the target frequency. Final measurement of TM010-π mode after welding and leak tightness

test was 703.265 MHz for expected 703.591 MHz. Because of the fabrication delay for this first

phase, we decided to prepare the cavity (field flatness and heavy BCP preparation) and to send

it back to RI for helium vessel welding before any vertical tests. So, we first BCP etched the

cavity surface of about 200 µm, then, we tune the cavity frequency and accelerating field profile.

The bare cavity was sent back mid of April and the delivery of the complete set (cavity with its

Titanium vessel) is foreseen in June 2013. Next step will be the preparation in clean room and

RF test in vertical cryostat at CEA-Saclay this summer.

For the β=1 cavity, the fabrication contract has started in April 2012. A review of the

manufacturing drawings has been done in July 2012. The forming of the cells by deep drawing

was performed in September 2012. Three sets of intermediate RF measurements on the half cells

and dumbbells have been organized at ZANON factory in presence of CEA. Two steps of RF

trimming were done on the four dumbbells and the two endgroups in order to tune each element

close to the target resonant frequency. After the final equator welding, the measured resonant

frequency of the accelerating mode is 703.747 MHz (703.04 MHz expected). Some upgrades of

the RF measurement tooling have been proposed to ZANON in order to improve the whole

procedure of frequency tuning before final welding. The cavity has been delivered to CEA

without its helium tank in May 2013 for the field flatness tuning. The electropolishing, the clean

room preparation with high pressure rinsing and the test in vertical cryostat is expected before

August 2013.

Figure 51: β=0.65 bare cavity ready for field flatness tuning at IPN Orsay, and β=1 cavity after final welding at

equators

The second main activity of this work package has consisted in the development of the new

Vertical Electro-Polishing (VEP) set-up. Additional experiments on single-cell cavities have

been carried out with new set of parameters. The use of a low voltage (6V) associated with a

high acid flow rate (25 L/min) has improved the surface finishing of the cavity.

Two single-cell cavities have been tested:

- 1AC3 cavity reached an accelerating gradient of 34 MV/m after 250 µm VEP. The

gradient has been limited by quench, with a heating area located at pits which have appeared

during early treatments with unsuitable parameters.

- 1DE1 cavity reached an accelerating gradient of 42 MV/m after 70 µm VEP. This cavity

has been previously treated on a standard Horizontal Electro Polishing (HEP) system and baked.

This result demonstrates that HEP and VEP configurations offer the same performances for this

cavity in term of gradient and improvement after baking.

Furthermore, VEP process with optimal set of parameters has been applied on a nine-cell ILC

type cavity from FERMILAB (initially horizontally electropolished). It was vertically

electropolished with the parameters previously described (~50µm removal). The observed

surface aspect on 1-cell and 9-cell cavities seemed similar. However, the achieved performance

on the 9-Cell cavity is limited due to heavy field emission. New VEP and RF test sequences are

planned to totally remove field emission.

1.1.10.3. Task WP10.3: LHC & CLIC Crab Cavities (CC)


The LHC-CC prototype fabrication at Niowave Inc. (not foreseen in the EuCARD contract) has

been completed and the cavity has been provisionally processed at CERN (see Figure 54 a) and

a first vertical test performed. The testing at SM18 was restricted due to a vacuum leak, however

the low field performance achieved was encouraging with respect to further testing to be

undertaken (see Figure 54 b). An optimised coaxial input power coupler has been developed

which is identical to the existing LHC accelerating mode cavities (see Figure 54 c) and a loop

type coupler has been developed for damping the LOM and HOM impedances (see Figure 54 d)

with integrated optimisation performed to achieve the required mode damping performance

required (see Figure 54 e).

Two CLIC-CC prototypes have been manufactured for high gradient testing, one by UK

industry (see Figure 55 a) and the other by CERN (see Figure 55 b) using the same manufacturer

as the main CLIC linac cavities. A conventional dual-feed input coupler has been developed to

transversely symmetrise the deflecting field (see Figure 55 c), with waveguide couplers proposed

to control the lower, same and higher order modes (LOM, SOM, HOM), with the most

threatening SOM requiring a damping to the order of Q ~ 100 (see Figure 55 d).

requirement of 5 fs. A control system model has also been developed to assess the performance

requirements for the LHC-CC system in the presence of beam. Beam protection issues

1.1.10.4. Task WP10.4: Thin films


The different tasks have made good progress. The development of the magnetron sputtering

technique at Legnaro has reached maturity. The RRR of the Nb sputtered samples was increasing

when increasing the power of sputtering. RRR values as high as 22 were obtained. In addition

the Nb film is uniform all over within the cavity. The deposition rate is also very promising: 1

micron in about 15 minutes is more than 10 times faster than the biased diode technique.

Legnaro is now fully ready to test this technique on a real cavity. However, due to the delays in

the production no cavity could be delivered to Legnaro yet. It is expected that the test could occur

after the summer.

The work in Lancaster was discontinued due to the departure of the person in charge. However

the topics have been addressed by Claire Antoine (CEA) in Chapter 5 of her EuCARD report

“Materials and Surface Aspects in the Development of SRF Niobium Cavities” (Vol. XII of

Editorial Series on Accelerator Science), which constitutes the groundwork for the new Thin

Films task of EuCARD2 which will address Hc1 improvements, ALD multilayers and Nb3Sn

thin film production, as well as new thin films test facilities (3rd harmonic Hc1 measurement).


M10.4.3 QWR sputtering with Nb using the magnetron technique: deposition parameters

have been validated with a stainless steel cathode. Due to the delays in the production no cavity

could be delivered to Legnaro yet but a novel sputtering set-up was thoroughly tested, leading to

a possible patent application.

1.1.10.5. Task WP10.5: HOM distribution


During the 3rd period, we have achieved our final goal within EuCARD of proving that HOM-

based Beam Position Monitors (HOMBPM) can be built for the 3.9 GHz accelerating module

(ACC39) in FLASH.

Sub-task WP10.5.1

Further analysis of the data collected with test electronics in Period 2 and defining the

specifications for the HOMBPM-electronics has been achieved. Although not the same

resolution can be achieved as for the HOMBPMs previously installed at 1.3 GHz in FLASH, we

have shown that the performance achieved with the test electronics, and therefore the one

expected to be achieved with the final one, will be an essential tool in aligning the beam on the

cavity axis, and reducing the beam-excited wakefields. Figure 57 shows the power integrated

around 5.44 GHz measured from each of the 8 HOM couplers as a function of the horizontal and

vertical magnetic steerer current, which is proportional to the beam position. Although each

distribution is different, due to the different ways that the various modes couple to each coupler,

they show a common minimum, which is the aim of the beam alignment procedure. The power

distribution has been studied also with trapped modes in the 5th dipole band. Herewith the

milestone 10.5.1 has been fulfilled.

Figure 57: HOM power around 5.44 GHz for each of the 8 HOM couplers

Based on these results, we decided to build two versions for the HOMBPM-electronics for

FLASH: one based on propagating modes around 5.44 GHz for precise beam position

measurements, and one using trapped modes around 9.06 GHz for localized measurements, both

with a bandwidth of 100 MHz. Two modules of the first type and six of the later will be built at

Fermilab. We expect to get similar or better performance as with the test electronics developed

within the EuCARD project.

They deal with the simulation of radio-frequency properties of ACC39. After creating and

validating computer models in the previous periods, one focus of the 3rd period was the

construction of model order reduction techniques, which are capable to determine secondary

quantities for multi-cavity structures apart from scattering parameters (external quality factors

or transient system responses). Proofs of principles for these methods have been presented

already for simple superconducting radio frequency structures (see literature). Beside of this

theoretical work, the influence of geometrical variations of individual cells in a nine-cell

resonator on the transmission spectra is investigated. The question whether the location of a

perturbed cell in the resonator is simply determinable by looking at the S-parameters was of

special interest. However, this turned out to be very difficult (inverse field problem) and needs

further investigations. Another focus was the dependency of the transmission spectra on input

coupler reflections (refer to Figure 58). Here it turned out that especially the second dipole

passband is very sensitive with respect to input coupler reflections.

1.1.10.6. Task WP10.6: LLRF at FLASH


After getting first results from system operation some system components were modified and

upgraded.

Multichannel Downconverter

The module performs the role of a field detector in the LLRF system. It has been optimized for

an input frequency of 1.3 GHz, a heterodyne of 1.354 GHz and an intermediate frequency of 54

MHz. High performance (low noise, good linearity, low crosstalk) has been verified in 2102 by

measurements of the final revision of the board (Figure 59).

Improved Vector Modulator

The vector modulator board performs the role of an actuator in an LLRF control system. The

RTM form factor provides enough space for two channels. The second channel will be used in

the future to perform system calibration. After extensive tests and requests for new features a

second revision of the board has been developed in 2012 (Figure 60shows a render).

downconverter module.

Synthesis and distribution of clock and reference signals in xTCA system

The RF backplane has been developed for the MTCA crate used in the LLRF system in order to

increase reliability and maintainability and to reduce the limitations arising from RF cabling. It

distributes high quality LO (local oscillator) and reference signals as well as low-jitter clock

signals. Low-noise analogue power supply is provided to analogue RTM modules. Final revision

of the board is still under tests. The final board installed in the MTCA crate is shown in Figure

61. In June 2012 the patent application for RF backplane was filled in.

Development of an AMC module with fast radiation sensors

It should be mentioned that on 9.01.2013 the patent was granted for “Solid State Neutron

Detection System” (EP 1 729 149 B1). The EuCARD predecessor CARE project supported this

work. It was a base for current development of the radiation monitoring board. During the

reporting period the AMC module for radiation monitoring has been redesigned to fit into

daughterboard of the FMC module.

Sub-task WP10.7.1: Slice emittance measurements of the SRF gun

This subtask was successfully finished within time. The final report was delivered in month 26.

The work was presented on the DIPAC´11 workshop and the EuCARD 2nd Annual Meeting.

The PhD student, Jeniffa Rudolph, who was responsible for the scientific part in this subtask

defended her thesis “Instruments and techniques for analysing the time-resolved transverse phase

space distribution of high-brightness electron beams” with great success in 2012.

Sub-task WP10.7.2: GaAs photo cathode

The work for the development of an advanced preparation system was continued. In the previous

part of the project (1) the existing system for CsTe cathodes was extended, and later (2) a new

small separate preparation system was build. In both systems the preparation of GaAs

photocathodes was tested, but without success. In the first system, the contamination and the

space for the installation of the components cause major problems. In the second chamber, the

unsatisfied vacuum was the main problem. Activation of GaAs wafers could be performed, but

the quantum efficiency was low and the lifetime was extremely short. The design of the small

preparation chamber and the results of the measurement tests are presented in the final report

D10.7.2. The conclusion of the project results is, to develop a more advance system which

includes the experience of the previous work and state-of-the-art technique in this field:

split of the cathode body and the new plug,

only the plugs are treated in the preparation system,

design of preparation system which can be installed near the electron gun,

using different chambers for cleaning, transfer and preparation.

Furthermore a standard design of the photocathodes, plugs and storage chambers was fixed

between the German institutes HZB, HZDR and University of Mainz. This required a further

redesign but will allow the exchange of photocathodes for tests and characterization between

these institutes in the future. HZDR gives additional funds for investment for this project of 200

k€ in 2012 and 2013. CAD design pictures are shown in Figure 67.

Sub-task WP10.7.3: Evaluation of critical Issues of SRF guns

A substantial progress was the delivery of the new two-channel UV driver laser for the gun in

2012. The work in this subtask was aimed to the following topics:

• Bunch compression studies and measurement of the longitudinal phase space applying the

phase scan technique.

• Operation of the gun with high average current and photocathode lifetime studies. With new

driver laser the average current could be increased up to 350 µA. The latest result is the

extraction of >300 C from a Cs2Te photocathode at a typical current of 300 µA.

• The dark current investigations were continued with comparative study for a series of different

photocathodes, and energy spectra were determined.

• A remarkable progress was the first FEL operation with the SRF gun at ELBE in April 2013.

1.1.10.8. Task WP10.8: Coupler Development at LAL


Subtask 10.8.1: Plasma cleaning of couplers


Doc. Identifier:

EuCARD-


Date: 15/10/2013


During the last period, surface treatment tests by plasma discharge were performed on coupler

cold part surfaces. The efficiency of the discharge in surface carbon removal was approved.

However, due to the presence 10% of oxygen in the gas discharge, an increase of oxides in

coupler surface was also observed which leads to the deterioration of coupler performances

(decrease of the RRR parameter). An optimization of gas discharge composition is needed to

avoid such effect. The changes in surface composition cause an increase of its roughness. This

effect is benefic for the RF conditioning process as it causes the lowering of surface secondary

electron emission yield (SEY). This observation must be confirmed by SEY of copper samples

before and after plasma treatment. In addition to an RF conditioning of the coupler part once the

process is fully optimized.

Subtask 10.8.2: Automatic couplers cleaning

After a first study phase providing the machine basic functions and all the components needed

for the cleaning process, a second extensive one was performed to choose the appropriate

technique among available solutions for the different functional steps. Thus, the machine design

evoluate continuously along the study advancement and the fixed choices.

Figure 68: Coupler cleaning machine evolution

Today, the internal and external mechanical structure ensuring functional motions of the system

are defined and its cost is estimated. The same is true for the ultrasonic system representing the

cleaning element. The specifications on hydraulic and air retreatment network are now well

defined, the drawings are ready and the cost is estimated. Further studies are on-going to optimise

the best technical solution for these two items.

Generally speaking, the studies are complete enough to give us a complete overview and

estimation of the feasibility, the process and the cost: the efficiency of the process, as far as the

large mass production is concerned, is undisputed. All the technical functions can be respected

to clean couplers automatically and correctly, without any damage for them.

1.1.11. WP11: assessment of novel accelerator concepts (ANAC)

WP11 ANAC is the ensemble of three R&D tasks of quite different nature and status, all

pertaining to novel accelerator concepts not covered by the other work packages:


Task WP11.2: Design of interaction regions for high-luminosity colliders

Task WP11.3: Upgrade of the EMMA FFAG Ring

Task WP11.4: Instrumentation for laser-plasma wake-field accelerators

1.1.11.1. WP11.1: coordination and communication


The WP11 web pages have been kept up-to-date with announcements of events, publication of

reports, meetings organized and other useful scientific information

(https://espace.cern.ch/EuCARD/WP11/default.aspx).

The preparation of the last deliverable of the WP was followed up.

1.1.11.2. WP11.2: Design of IR for high luminosity colliders

The main purpose of Task 11.2 was to prove the compatibility of large magnetic detectors with

a new collision scheme based on large Piwinski angle, low–β and Crab-Waist compensation of

the synchro-betatron resonances. Subtask 11.2.1 aimed to apply this collision scheme to the new

DAΦNE Interaction Region (IR) for the upgraded KLOE-2 detector running same time Subtask

11.2.2 has studied the possibility to use the Crab-Waist collision scheme for the luminosity

upgrade of the LHC. Both subtasks have been successfully completed.

The work foreseen for this EuCARD Task was successfully completed in April 2011 (P2).

The reminder of the EuCARD period has been aimed at optimizing the collider performances in terms of

luminosity for the data-taking for the KLOE-2 experiment. Figure 69 shows a sketch of the final KLOE2

Interaction region.

Figure 69: KLOE2 upgraded IR

Several hardware upgrades have been done in order to improve the collider performances. Among these,

the installation of “clearing electrodes” in the dipole and wiggler vacuum chambers of the positron ring,

to have an almost complete neutralization of the emitted photo-electrons in the e-cloud instability

formation. The experimental measurements on the electrodes effectiveness in mitigating the electron-

cloud effects have proved that they work in increasing the threshold current at which the instability occurs,

so allowing for a higher injected positron current. In Figure 70 the horizontal instability growth rate as

a function of the electrode voltage, as measured using the bunch-by-bunch feedback, is shown.

A massive campaign for further hardware upgrades has been conducted during the 2013 shut-down

(required to install the new layers of the KLOE-2 detector), both in the rings and in the injection complex.

This work will continue after the end of the EuCARD project.

Sub-task WP11.2.2 study of a high luminosity Interaction Region for LHC

The work for Subtask 11.2.2 was delayed due to the problem in recruiting manpower at CERN. This

problem was solved and a doctoral student position was awarded starting from November 2010. For these

reasons the Deliverable 11.2.2 (Study of an IR design for LHC upgrade, CERN) was postponed to M48.

An elegant conceptual optics solution for a future LHC luminosity upgrade, combining flat beams, local

chromatic correction, large Piwinski angle and the option of crab-waist collisions. The scheme requires a

non-zero slope of dispersion at the IP and a new single-aperture final focusing element, which combines

dipole and sextupolar field components. The quadrupole feed down field focuses both beams in the

vertical plane. The sextupole component together with the non-zero dispersion is used to correct the

chromaticity locally. Orbit, dispersion and beta functions were matched to the existing LHC arcs.

Dynamic aperture is still a concern. The geometric aberrations could be corrected perfectly by a second

sextupole if the magnets were short. However the double half quadrupole is quite long, which introduces

intrinsic octupolar aberrations in addition to rendering difficult the compensation with a second sextupole.

A segmentation of the final quadrupole, to confine the sextupole field to a shorter region, is proposed as

mitigation. A similar final focus system, for a single beam was designed and qualified for the LHeC.

Possible merits of, and parameters for, applying the described approach at the HE-LHC have also been

investigated. Successful beam experiments testing key concepts, like crab-waist, large Piwinski angle and

flat beams, were conducted, analysed and prepared at DAΦNE and at the LHC, respectively.

In P3, the following experiments have taken place. For the acceleration of muons, the acceptance

of the accelerator and the dependence of the time of flight of a particle around the accelerator on

the distance from the ideal orbit have both been measured. The latter is as expected. The

measured acceptance is ~1 π mm mrad. Further studies of the COD have been made and an

additional source of perturbation in the horizontal plane identified: the stray field from the

injection septum. In the longer term, it can be fixed by replacing this device, but in short term

corrections have been found which reduce the COD both horizontally and vertically.

More general studies have also been undertaken. These include a successful experiment to

demonstrate the principle of phase rotation planned for the PRISM project. Work is also on-

going to study the effect of tune crossings. In particular, it has already been shown that these

crossings have no impact when the beam is accelerated at the fast rate required for muon

acceleration. The question remains how slow the acceleration can be before these crossings

become a problem. This is important for the use of this type of accelerator for the acceleration

of non-relativistic particles, especially protons, for a variety of medical and other applications.

1.1.11.4. WP11.4: instrumentation for novel accelerators

Task WP11.4 aims to study new instrumentation to diagnose parameters, such as emittance or

relative energy spread, of electron beams produced by laser plasma accelerator. An experimental

methodology is needed because of the present produced low shot to shot reproducibility. The

study will take different approaches for measuring the emittance of these electron beam delivered

by laser plasmas accelerators.



Studies have continued on the source and influence of the electron angular momentum. This

came as a surprise because injection models predict that electrons should be injected in the

accelerator with a zero angular momentum. The growth of the angular momentum was explained

by the fact that the laser pulse creates an asymmetric plasma cavity (because it is itself

asymmetric). Electrons which are accelerated in this cavity oscillate with different frequencies

along the two transverse directions, inducing an evolution of the electrons' angular momentum

during the acceleration. This explanation for the origin of the angular momentum is supported

by experimental results and simulations, which agree very well. For example, Figure 71 shows


Doc. Identifier:

that for a cavity ellipticity of 20%, a very good agreement between simulations and experiments

is obtained. Thanks to this result, the simulations could be used to estimate the emittance using

both the spatial and spectral measurements. Doing so an emittance of 1 π.mm.mrad was found,

consistent with previous estimates and particle-in-cell simulations. This result comforts the

Deliverable of WP11.4.

2.3 PROJECT MANAGEMENT DURING THE PERIOD

In this last project period, the focus of the management has been to simultaneously maximize the

S/T activities outcome, mitigate the exceptional documentation effort requested from all

researchers and coordinators while maintaining a collaborative spirit by organizing a smooth

transition to EuCARD2 and creating a final brainstorming event around the medium term future

of accelerators for research and applications.

1.1.1. Consortium management tasks and achievements

EuCARD has continued benefitting from stable environment and priorities. Even though the

collection of report of activities and of deliverables remains somewhat challenging, the

significant experience accumulated by the management bodies, Governing Board, Steering

Committee and Project Coordinator on one hand, and the standardized project management

instruments on the other hand, now well-known from all participants, have allowed a smooth

P3 exercise.

The P2 periodic report was delivered with a minor delay. One of the report requirements, given

the large scope and number of tasks of the project, is to efficiently summarize the project

activities using a standardized reporting format experimented in P1 and for interim reports. Each

project task, in most cases involving the collaborations of several partners, is allocated a single

page for scientific progress and achievements, ½ page for management information (schedule,

use of resources) plus space for pictures. This compactness requires a special effort from

researchers, task, work package and project coordinators in selecting the essentials for

presentation, in a way respecting the efforts from 38 partners.

Special care was allocated to the concluding EuCARD meeting, with the goal of maintaining the

spirit of collaboration and hand it over to EuCARD2 or other ventures: The first meeting day

was dedicated to the report of EuCARD achievements from a managerial point of view, with a

final assessment by the Governing Board. The next two days were organized as a workshop with

the ambitious theme of ‘visions for the future of accelerators” for the next 50 years. The invited

speakers were for many world experts, with a significant EuCARD participation, and the

response to this challenge was excellent, as well as the attendance of all parts of this

concluding/workshop/kick-off meeting. The scientific organization of this workshop was a

collaboration of the EuCARD and EuCARD2 project coordinators, and of the coordinator of the

very successful EuCARD WP4 “Accelerator networks”. One of its sessions was covered by the

CERN communication team, with an article in the CERN Courier. The technical organization

was carefully prepared by the project assistant, with help and sponsoring from CERN. Always

in the spirit of consolidating collaborations, the project assistant organized the NBI2012

workshop in support of WP3. She equally gave support to the ESGARD committee meetings,

the meetings at CERN of FP7 ICAN and the activity of FP7 CESSAMag.

EuCARD being extended by 4 months with conditions, the Administrative Manager gave support

to many partners in the interpretation of the conditions.

An important dimension of the management activity and results for EuCARD is the external

relations, both to keep EuCARD in line with the trends in the field and to contribute to sustained

collaborations in the community. This is reported in sections 2.3.7 and 2.3.8.

1.1.2. Budget adjustments

No budget adjustments needed to be carried out during the reference period. The final

distribution of the EC funding to each beneficiary will be decided by the Governing Board after

the submission of the final report, taking into account the estimated full costs incurred by each

partner with respect to the commitments in Annex I.

1.1.3. Problems and solutions

During Period 3, the project has not faced significant problems that could not be essentially

resolved at the task’s level.

1.1.4. Changes in the consortium and/or legal status of beneficiaries

No changes were recorded in this last EuCARD period.

1.1.5. Project meetings

The meetings of the whole project and of its Governing Board and Steering Committee are given

in the next table.

1.1.6. Project status

At the end of the project, almost all milestones have been met, not more than 10% had had to be

rescheduled due to delays, some were fulfilled ahead of schedule and a minor number were either

cancelled for lack of relevance, or combined with their respective deliverables. Milestones have

played an important role in monitoring the progress towards deliverables, as most deliverables

are by essence scheduled at the project end.

Out of 63 contractual deliverables,

59 are delivered as planned.

one is delivered by another partner of the collaboration, after the resignation of a key

person at the lead partner. This deliverable is as well published in the EuCARD

monograph series.

three important deliverables will be fully documented during the project but will reach

full completion after the project end: one with about a one month delay (super-

conducting proton cavities), another with a five month delay (HTS insert) and the third

one with a delay estimated at 1.5 years. In the first case, the delay is explained by a

delayed order, following an unexpected cost increase, requiring the mobilization of

unplanned partner funds. In the second case, initial technical difficulties in this risky

R&D line are at the origin of the few month delay. All components have been

delivered, but the assembly and test will be carried out in the last part of 2013. In the

last case (High Field magnet model), 50% of the delay is due to the case of force

majeure after the LHC incident, where all magnet engineers were mobilized for the

repairs during one year. The other 50% are explained by additional iterations that

became required, given this new and very challenging technology, in agreement with

the recommendations of an international expert committee. The progress made by the

European team is judged excellent by the US experts, where much larger funds have

been dedicated to the topic over two the last two decades.

The two EuCARD Transnational-Access facilities have fully fulfilled their objectives and

beyond. WP5 had suffered a delay of 2 years due to the LHC incident; its very efficient recovery

has allowed fulfilling the contract. WP6 almost doubles its contractual commitment, by a strict

control of expenses and the donation of the TA management time by STFC.

scope in EuCARD2.

1.1.7. Communication

Even though the communication activity is conducted in WP2, it is tightly linked to the

management, with the deputy of WP2 being a member of the Coordination Office. The strategic


Doc. Identifier:

Date: 15/10/2013


extension of the EuCARD Newsletter to three other FP7 accelerator projects, as a first phase

towards extending it to the whole accelerator community has been effective over this period. The

experience is positive and this new electronic publication is taken over by TIARA-PP with the

termination of EuCARD.

1.1.8. Coordination of activities between beneficiaries and synergies with other projects

An essential ingredient of success for EuCARD as a collaborative venture is to remain integrated

in the accelerator R&D programmes carried out on a national or laboratory basis, which provide

2/3 of the project funding. In this respect, the selection of EuCARD tasks and coordinators has

been instrumental. The coordination between beneficiaries is efficiently done at the task level,

with the EuCARD activities embedded in local projects, and providing the added value of a

collaborative venture. One indication is the number of conference publications, signed by authors

within and outside EuCARD.

To further strengthen the links between EuCARD beneficiaries, the face-to-face Steering

Committee meetings and the Annual meetings have been held in different laboratories. On each

of these events, either half a day (for SC meetings) or a full day (for annual meetings) is dedicated

to the host laboratory/state and beyond, including political and scientific talks and discussions,

and visits of accelerator infrastructures. In P3, the steering committee meeting organized in

Uppsala University was only partly faced to face, a snowstorm preventing landing in Stockholm;

the Annual meeting of 2012 took place in Warsaw, hosted by Politechnila Warszawska, , and the

Concluding meeting of 2013 at CERN, as coordinator. Once again, the “host day” in Poland was

a very valuable opportunity to demonstrate the R&D potential of Polish Institutes. ESGARD

organized as well a satellite meeting during these two EuCARD annual meetings.

The network events (mainly topical workshops) are privileged opportunities to create links

between the EuCARD beneficiaries and beyond, especially the US and Japanese partners, who

have been active participants. The WP3 network on neutrino facilities published important

synthesis documents proposing perspective for this branch of physics, used as input in the update

of the European policy for HEP. After setting up collaborations on superconducting crab cavities,

LHC luminosity and energy upgrade and novel acceleration techniques in the former periods,

the WP4 accelerator network has continued to be the birth place or catalyser of collaborative

“start-ups” active on major new perspectives for frontier accelerators, such as TLEP and

VHELHC, gamma colliders,…

The coordinators of EuCARD and EuCARD2 are tightly collaborating, for an optimal

transmission of experience. This is further consolidated by a common coordination office.

Whether on behalf of CERN or ESGARD, in the latter case together with its chairman R.

Aleksan, the coordinator has visited the EC or participated, with the Administrative Manager, to

the CERN delegations hosting visitors from the EC, keeping contact and explaining the

motivations for the R&D in accelerators. The project coordinator represents CERN and

EuCARD in the FP7 ICAN project, creating a link between the laser and accelerator

communities. He coordinates as well the FP7 CESSAMag project, whereby the European

Commission and CERN organize a support to SESAME, in the framework of Euro-

Mediterranean scientific cooperation.

The EuCARD administrative manager, in is duty of head of the CERN EU Office, frequently

visits the EC, keeping an efficient link that profits all EuCARD partners.
