Carsten P. Welsch, Coordinator

After 5 years, you are now reading the finalversion of our oPAC newsletter. Your input,contributions and feedback have made it agreat resource for the wider acceleratorcommunity and triggered many interestingdiscussions.

You will see in this issue that the research ofour Fellows is far from having come to an endwith results now being published in peer-reviewed journals and also PhD theses beingfinalized. In the future we will communicatefurther news from our Fellows and projectpartners primarily through social mediachannels of the University of Liverpool andthe Cockcroft Institute; and of course therewill also be news and updates at our well-known IPAC and IBIC conference stand.

oPAC has linked and served the acceleratorcommunity very well. The project has enabledclose collaboration between machinedesigners, beam instrumentation specialists,as well as code developers. Our Fellows havebuilt up a very remarkable skills set which Iam sure will be an excellent basis for theirfuture careers, they have also enjoyed theirtime within the network very much – as youcan read for example in Pavel’s interview inthis newsletter.

Our oPAC schools and topical workshops havebeen an enormous success, attracting up to120 participants and establishing acomprehensive set of presentations on ourindico sites that will benefit acceleratorexperts for years to come.

It makes me very proud to look back at whatoPAC has achieved over its life time and amvery happy that I was part of this fantasticinitiative. I would like to use this opportunityto thank all our Fellows for their hard workand friendship, our project partners and thewider community for their supportthroughout the years, and my TEAM for theirgreat work.

Let’s see what the future brings. There isclearly much more need and demand forhighly skilled experts in the wider acceleratorsector. Areas such as laser-based acceleratorsthat aim at demonstrating highestaccelerating gradients whilst providing goodoutput beam quality would surely benefitfrom a coordinated international trainingeffort and it would be great to see that a newinitiative arises on the foundations that oPAChas now laid.

Turn-by-turn measurements of transverse impedance in a synchrotron light source – Michele Carlà

Transverse beam coupling impedance is asource of beam instabilities that limits theperformance of circular accelerators. Severalbeam based techniques have been used tomeasure the transverse impedance of anaccelerator, usually based on the opticsdistortion produced by the impedance sourceitself. Beam position monitor turn-by-turnanalysis for impedance characterization hasbeen usually employed in large circumferencemachines, while synchrotron light sourceshave mainly used slow orbit basedtechniques.In a paper just accepted in the journalPhysical Review Accelerators and Beams,oPAC fellow Michele Carlà and co-workers

from the ALBA synchrotron in Spain havepresented for the first time the results ofturn-by-turn impedance measurements atALBA, advancing the measurement techniqueinto the range of the typically smallimpedance values of modern light sources.The authors measured local impedancecontributions through the observation ofphase advance versus bunch charge using thebetatron oscillations excited with a fast dipolekicker. The ALBA beam position monitorsystem and the precision of the turn-by-turnanalysis allowed to characterize the mainsources of transverse impedance, in goodagreement with the model values, includingthe impedance of an in-vacuum undulator.

Non-invasive intensity measurements of low energy beams demonstrated for the first time – Miguel FernandesA precise measurement of absolute beamintensity is essential for many experiments.It is a key parameter to monitor losses in abeam and to calibrate the absolute number ofparticles delivered to the experiments.However, this type of measurement is verychallenging with traditional beam currentdiagnostics when it comes to low energy, lowintensity beams due to the very low signallevels.oPAC fellow Miguel Fernandes andcolleagues from the University of Liverpool,have now experimentally demonstrated anew type of monitor in collaboration withCERN, the GSI Helmholtz Centre for Heavy IonResearch and Friedrich Schiller University andHelmholtz Institute Jena.The Antiproton Decelerator (AD) is asynchrotron machine that provides low-energy antiprotons for studies of antimatter.These studies typically rely on creatingantimatter atoms (such as anti-hydrogen) andusing them as probes for the mostfundamental symmetries in nature such asthe invariance of CPT, or of the gravitationalacceleration on matter and antimatter.

A precise measurement of the beam intensityin the AD is essential to monitor any lossesduring the deceleration and cooling phases ofthe AD cycle, and to calibrate the absolutenumber of particles delivered to theexperiments. However, this is ratherchallenging with traditional beam currentdiagnostics due to the low intensity of theantiproton beam which is of the order of 107particles, corresponding to beam currents aslow as a few hundred nano-Amperes. To copewith this, a Cryogenic Current Comparator(CCC) based on a Superconducting QUantumInterference Device (SQUID) was developedand installed in the AD, in a collaborationbetween CERN, the GSI Helmholtz Centre for

Heavy Ion Research, Friedrich SchillerUniversity and Helmholtz Institute Jena.

Previous incarnations of CCC’s foraccelerators suffered from issues concerningsensitivity to mechanical vibrations andelectromagnetic perturbations. Furthermore,these setups were used for measuring slowbeams, usually from transfer lines ofaccelerators, and were unable to measureshort bunched beams presenting fast currentvariations. In order to measure the beamcurrent and intensity throughout the cycle ofa synchrotron machine such as the AD, theCCC needed to be adapted to cope with thefast signals of bunched beams.

In an open access paper just published in theIOP “Superconducting Science andTechnology” journal, oPAC fellow MiguelFernandes and co-authors describe thechallenges of implementation and first beammeasurements. These are the first-ever CCCbeam current measurements performed in asynchrotron using both coasting and shortbunched beams. The paper demonstrates theexciting prospects of this new type of beamdiagnostics device.

How to build a particle accelerator at homeThe University of Liverpool’s Quasar Grouphas launched a series of outreach videoswith instructions on how to build some basicexperiments related to accelerator science.The videos demonstrate fundamentalconcepts of electromagnetism likeelectrostatic potential and magneticinduction, including instructions on how tobuild a Van de Graaff generator, a rail gun, asalad bowl accelerator, and an electric motor,all of them using household materials.

The experiments were designed for a series ofoutreach workshops on acceleratorengineering for 13 – 14 year old schoolchildren. The events, funded by the RoyalAcademy of Engineering and the Science andTechnology Facilities Council (STFC), wereheld over the summer at the CockcroftInstitute and proved a massive hit with thechildren. With the videos now on YouTube,the activities can be replicated at home or inthe school laboratory.

Xavier Nuel Gavaldà awarded PhD degree Xavier defended successfully the PhD of theUniversity of Paris-Saclay on September 6th

2016.The thesis was hosted in Synchrotron SOLEILand it was dedicated to the optimization ofthe nonlinear beam dynamics of synchrotronradiation light sources using Multi-ObjectiveGenetic Algorithms (MOGA-ELEGANT). In thefirst part the ELEGANT code wasbenchmarked against TRACY3; then MOGAwas tuned and used to find the best settingsof quadrupole and sextupole magnets inorder to maximize the dynamic andmomentum apertures, strongly related to theTouschek lifetime and the injection efficiencyrespectively. Solutions obtained after onemonth of computation in the high levelcomputational cluster of SOLEIL using 200CPUs were analyzed. The improvement of theTouschek lifetime obtained with MOGA wasconfirmed by the beam-based experiments.The beam lifetime of the SOLEIL storage ringwas increased by 40–50 % while keeping the95% injection efficiency.The second part of the PhD work was devotedto study experimentally the beam lifetime of

the SOLEIL storage ring to improve theunderstanding of the beam lifetime and itscontributions: the Touschek and gas lifetimes.The beam lifetime was measured in functionof important parameters as coupling,horizontal and vertical scrapers, and bunchcurrent. The experimental results werecompared with the simulated ones. Thecomposition of the residual gas and the localpressure along the entire machine varysignificantly between the arcs and the in-vacuum insertion devices: new effectiveatomic numbers were obtained. This type ofmeasurement remains difficult to analyzewithout a large error margin; in-vacuuminsertions have a dominant contribution. Theshape of the experimental curves is closed tothe expected ones and compatible with aneffective atomic number of about 7.Xavier would like to thank for the supportreceived of oPAC during his work atSynchrotron SOLEIL.

Interview with Pavel MaslovPavel was born and raised in St. Petersburg, Russia. In 2004 he was enrolled into the faculty ofRobotics and Technical Cybernetics. Pavel went to the military department of the PolytechnicUniversity as Reserve Officer of the Anti-aircraft Rocket Forces in 2010. During his 6th year at thePolytechnic he also he worked as a volunteer in AIESEC, a global youth non-profit organization thatdevelops leadership capabilities. Pavel earned his bachelor’s and master’s degrees in automationand control with honors. His master’s thesis was entitled ‘Precise control of the Stewart platform(hexapod robot)’.In December 2010 Pavel was employed as engineer and programmer by the D. V. Efremov ScientificResearch Institute of Electrophysical Apparatus, were he got involved in the ITER project,implementing a distributed control system (based upon EPICS) in ITER’s Fast Discharge, and a dataacquisition system for the high-current test stand at the Pulsed Power Lab. Pavel received a MarieCurie fellowship within the oPAC project at Cosylab in Ljubljana, Slovenia, in May 2013. His mainfocus was the study and optimization of control systems for large physics machines, includingparticle accelerators, fusion reactors and radio telescopes.

What did attract you to the oPAC network?Has it fulfilled your expectations?Back in the day (oh how many years havepassed, unbelievable) I had just started todiscover the area of control systems forscience. Personally, I had an interest andliking of international collaboration, and oPACwas a good chance for me to get internationalexperience (which I desperately needed), andprimarily professional experience in a fieldthat is not covered in any university course. Ishould point out that I was intending to gostudy in the US, I applied for the Fulbrightgrant, was considering different labs to workat. But in the end, Europe was closer andmore accessible, so I changed my mind.Besides, I was advised to try Cosylab by oneof the members of the EPICS community, so Idecided to give it a go.

Why did you choose to go to Cosylab?I knew Cosylab because we collaborated onthe ITER project together while I was workingat the Efremov Institute. They wererecognised as the leader in softwaredevelopment and control systemsmaintenance for scientific installations. Iwould read their monthly newsletter with thelatest achievements in the field and I gotreally hooked. I thought, that I could get verygood-quality hands-on experience there. Andas it turned out I never regretted :)

Can you explain in a few words what yourproject was about and what have youachieved?The project was dedicated to the study ofopen source control systems and putting allthose small tools into a single productcapable of quickly managing a set of typicaldevices (physics sensors, valves, etc.) andintegrating them in the EPICS control system.As a result I have come up with the DCDBtool, which helps accelerator personnelduring commissioning of the equipment, aswell as engineers and researchers, who cansimply build their experiment using bottom-up approach.

What has oPAC provided you professionally?First of all, as an engineer I didn't have propereducation in Computer Science. oPAC (withthe help of Cosylab) helped me to fill in thegaps and become a decent softwaredeveloper. Secondly, I wasn't a particlephysicist either, but rather a fusion / pulsed-power engineer. During the intense trainings,conferences and workshops that oPAC hasprovided, I have learned a lot in this newarea, too. Last but not least, I have had achance to meet professionals and scientistsfrom all over the world and exchange lifelongcontacts (both professional and human).

What are your professional plans now thatoPAC has finished?After oPAC had finished, I decided to gainsome in-depth knowledge in the field ofinformation systems for the enterprise. So Ispent nearly six months at the laboratory ofinformation systems of the University ofLjubljana, participating in 2 EU projects,namely AgroIT and Flexiciency.Right now I am developing the decisionsupport system for an EU project calledHeartman together with colleagues from theLaboratory of Ambient Intelligence of theJozef Stefan Institute in Ljubljana, Slovenia.Generally speaking, I am planning to stay in ITand wish to become an experienced andversatile IT professional.

What will be your most cherished memoryfrom oPAC?I cannot define just one, everything Iexperienced was new and exciting to me.Perhaps, my first ever trip across Europe,visiting CERN, playing frisbee with the youngfellow physicists in the campus lawn. Myinternship in Stockholm was great, too -playing curling, yeah! And IPAC 2014 - trying aroasted piglet on a spit with Carsten and Co.Priceless!

And the one you’d rather forget?nah :)

Happy birthday, Sir James ChadwickOn 20th October the University of Liverpoolcelebrated the 125th birthday of one of itsmost illustrious members, Sir JamesChadwick.Chadwick, who was born in 1891 anddiscovered the neutron in 1932, became aprofessor of physics at the University ofLiverpool in 1935, the same year he wasawarded the Nobel Prize in Physics.Chadwick earned his PhD in 1921 under thesupervision of Ernest Rutherford at theCavendish Laboratory, University ofCambridge. He worked as Rutherford'sassistant director of research for over adecade at the Cavendish Laboratory, wherehe made the famous breakthrough. Chadwickfollowed the discovery of the neutron bymeasuring its mass, and anticipated thatneutrons would become a major weapon inthe fight against cancer.After taking his position in the Department ofPhysics at the University of Liverpool,Chadwick overhauled an antiquatedlaboratory and, by installing a cyclotron,made it an important centre for the study ofnuclear physics. Therefore, the current statusof the University of Liverpool as one of theworld’s leading institutions in nuclear,

particle, and accelerator physics drawsdirectly from Chadwick’s work.Likewise, the university’s position as aninternational hub for the training ofaccelerator experts, through coordinatinginternational research and training networks,such as oPAC, can be said to be part ofChadwick’s legacy.

ELENA in Wonderland

At the start of Lewis Carroll’s Through theLooking-Glass, young Alice wonders whatlife would be like in the house at the otherside of the mirror, before being magicallytransported into it.Almost a century and a half after thepublication of the celebrated tale, physicistsat CERN have made this crossing through thelooking-glass a reality. As a token of theinverted world to be found there, the particleaccelerator scientists had to build anantiparticle decelerator.

The so-called Antiproton Decelerator (AD),slows down antiprotons to an energy of 5.3MeV. In service since 2000, the AD has beenhelping scientists address fundamentalquestions like the effect of gravity onantimatter or the imbalance between matterand antimatter in the Universe.The lowest the energy of the antiprotons theeasier it is for the experimenters tomanipulate and study them. A new machinecalled ELENA (Extra Low ENergy Antiprotondeceleration ring) has been built to slow theantiprotons down even further, to just 0.1MeV. In addition, the density of the beamswill be improved, increasing the amount ofdata available for experiments.

ELENA measures 30 metres in circumferenceand has just begun its first tests with beam.After the tests have been finalised, theantiprotons will be sent to experiments werethey will be used to produce atoms ofantimatter and study its properties.

oPAC fellow Miguel Fernandes has had animportant role in the development of theAntiproton Decelerator by designing andbuilding a new type of monitor to measureaccurately the extremely low intensities ofthe antiproton beams (of the order of a fewhundreds of nano-Amps).A precise measurement of the antiprotonbeam intensity is essential to monitor anylosses during the deceleration and coolingphases of the decelerator cycle, and tocalibrate the absolute number of antiparticlesdelivered to the experiments.In a paper just published in the IOP“Superconducting Science and Technology”journal, Miguel Fernandes and co-authorsdescribe the challenges of implementationand first beam measurements of a CryogenicCurrent Comparator (CCC) based on aSuperconducting QUantum InterferenceDevice (SQUID). The paper demonstrates theexciting prospects of this new type of beamdiagnostics device.
