Status of the ILC

In August 2004, group of “Wise Men”, chaired by B. Barish,chose the “cold”, superconducting, RF technology over thecompeting “warm” X-band RF.

Despite the fact that both US and Asian research had been in warm technology, both regions accepted the decision andunited behind cold technology; now, transition is complete.

ICFA moved ahead quickly to appoint a Global DesignEffort (GDE) to transform the technology decision into afull Technical Design Report, capable of being presented toworld governments for a decision to construct.

B. Barish appointed as GDE director, with three regionaldirectors:BF (Europe), F. Takasaki (Asia), G. Dugan (Americas)

Status of the ILCAt end of April, EPP2010 panel produced its report. Thisconcluded that it was very important that the US regained itsleading position in particle physics, under clear threat withthe closure of all US domestic pp accelerators by end of thedecade. It gave a ringing endorsement for the ILC strategy,requested increased US investment in the R&D for both machine and detector and gave strong support for the US bidding to host the machine. The CERN Strategy group met last week in Zeuthen.Although its conclusions remain confidential, I believethat the current draft document to be submitted to thespecial CERN Council Session in July contains a strongendorsement of the ILC and a recommendation thatEurope, and CERN, are strongly involved in it throughthe GDE.

GDE mission

Currently GDE is 64 strong :Americas - 22;Asia - 18;Europe - 24; corresponding to ~ 30 FTEs.

• Produce a design for the ILC that includes a detailed design concept, performance assessments, reliable international costing, an industrialization plan , siting analysis, as well as detector concepts and scope.

• Coordinate worldwide prioritized proposal driven R & D efforts (to demonstrate and improve the performance, reduce the costs, attain the required reliability, etc.)

ILC Parameters

• Ecm adjustable from 200 – 500 GeV

• Luminosity ∫Ldt = 500 fb-1 in 4 years

• Ability to scan between 200 and 500 GeV

• Energy stability and precision below 0.1%

• Electron polarization of at least 80%

• The machine must be upgradeable to 1 TeV

BCD overview

Baseline Design completed in December 2005 overseen by Executive: Directors + T. Raubenheimer, N. Walker, K. Yokoya.

MAC report

Generally they were very positive and impressed by the scale of the progress that has been made. They had concerns aboutthe current accelerating gradient spec. and how R&D could be done to achieve it, about communications with the experimenters and also about coordination of world-wide R&D.

The first meeting of the Machine AdvisoryCommittee, which reports to ILCSC, tookplace last month in Fermilab & examined theBCD.

Klystron Fabrication Several suppliers for BCD:

But none meet performance requirements -may need to go to 5 MW.

Test facilities

TTF exists at DESY, SMTF (FNAL), STF (KEK):

Stimulate SCindustry in theregions -collaborate onSC technology


14

Next steps for GDE

BCD is “complete”. In the next phase, RDR will take forward the BCD, refine thedesign and in particular gather industrialisation data in order to form the basis for reliable cost estimate with the RDR.

There are 3 new boards: Change ControlBoard; Global R&D Board; Design & CostBoard.

Change control The board has overseen the consolidation of the baseline design and the production of aWord document containing all information. Dealing with requests for changes to baseline as further work and R&D is completed. Careful methodology developed - categorisethe importance of the change, assignnumber of board members to review itdepending on importance. During process, all GDE members can comment on proposed change. Dealing with~ 1 request/week.


17

Other boards Design & cost board produced a (very)detailed programme of work to lead ustowards the most important RDR deliverable- a believable, robust and affordable costing; a preliminary, non-public version will be available by the summer Vancouver meeting.

R&D board has to try to impose a structureand discipline on inherently chaotic system- R&D - eliminating wasteful duplication while preserving & enhancing necessary duplication.

Next steps

The meetings are going well and detailedprogress is being made.

The day-to-day work of constructing theRDR is supervised by an RDR boardchaired by N. Walker (DESY) which meets every week by telephone and reports tothe ILC Executive Committee.


25

European GDE

European GDE meets about every 6 months. Discusses obviously regional issues:- how to get more resources from inside Europe, in particular the EU;- regional outreach - Europe has particulardifficulties & challenges here.

The European GDE does NOT discuss thetechnical issues of the BCD or take up European positions on them - these arematters for the full GDE.


26

European GDE

European Outreach group re-established atOrsay meeting in January. B. Warmbein joined the team recently as PA to EGDE director, based at DESY. Meeting held inDESY just before Easter.

EGDE director’s advisory group also meetsregularly.


27

European GDE Yesterday evening we had an EGDE meeting in DESY to discuss the shape of the EU FP7 proposal. We heard about European cryogenic RF development centre to be citedat CERN, about possible continuation of some current FP6 activities, the use of HERA as a prototype damping ring, etc.

ELAN/EuroTeV Meeting at Orsay next Mon-Weds will also discuss these ideas. Goal to have an action plan & outline strategy in next few weeks.

Summary

The ILC is making excellent progress and the GDE is well established.

Producing the RDR & the cost estimate by theend of the year is going to be very tough - weneed all the help & expertise that we can get.

This is a very exciting and challenging enterprise that is vital for the future of world particle physics.
