1. MICE FAC meeting 15-7-2011 1 MICE spokesperson report

2. MICE FAC meeting 15-7-2011 2 -- Steve Gourlay (LBNL head of Accelerator and Fusion Research Div.) now in charge of the Spectrometer solenoids and Coupling Coil magnets. -- MICE magnet coordination established: Mike Courthold (RAL) and Roy Preece (RAL) -- MICE PM Andy Nichols more available: -- MICE-UK project manager appointed (Alan Grant, DL) -- Gail Hanson (UC Riverside) will support PM as MICE schedule coordinator -- We have welcome University of Strathclyde (Glasgow) in the MICE collaboration Personnel issues

3. MICE FAC meeting 15-7-2011 3 We are short of experienced accelerator physicists in MICE – especially in preparation for steps V-VI! others: -- Linda Coney takes over from JSGraulich as Online Group Coordinator -- Yordan Karadhzov takes over from JSGraulich as DAQ expert -- Adam Dobbs takes over from M. Apollonio as beamline expert -- Mike Zisman stepped down as deputy spokesperson to take on assignment at DOE (replacement as D.S. and in executive board under discussion) -- significant crunch on software effort (transition from G4MICE to MAUS) Important that groups responsible of detectors or hardware keep ownership of the associated software! ex: TOF Milano (INFN), Tracker Japan, UK, US, EMR Geneva, etc.

4. MICE FAC meeting 15-7-2011 4 Publications Two journal papers in preparation with RESULTS Measurement of the MICE muon beam emittance using the single particle method deadline for comments 21 July 2011 being finalized + tracker paper and TOF paper published, many conference publications (see report)

5. MICE FAC meeting 15-7-2011 5 MICE report to MPB concentrated on schedule issues -- MICE schedule review 23-25 May 2011 in presence of internal reviewers Atkinson(DL), Kerby(FNAL), Nessi(CERN) Strongly endorsed significant accomplishment before long ISIS shutdown -- Punchline: 1.STEP IV schedule established -- much progress on SS, now plan and milestones -- MICE decided to skip step II and III  run step IV in October’12-March’13 2. Step V -- “Aspirational”: have a significant running of step V before the long ISIS shut down Aug 2014-Feb 2015. Priority over more step IV running Depends critically on RFCC delivery This strategy was endorsed at MICE CM30 in Oxford 6-9 July’11 it is now “MICE-official” Today: will concentrate on step IV running and step V-VI preparations -- MICE running -- Coupling coils -- RF power and delivery system

6. MICE FAC meeting 15-7-2011 6  MICE SCHEDULE -- update July 2011 completed -> Aug2010 STEP I STEP IV Q3 2012 STEP V Q2 2014 *) STEP VI Run date: completed -> Aug2010 EMR run Q1 2012 *) target date, necessary to run step V before long ISIS shut-down Aug.2014-Feb.2015

11. MICE FAC meeting 15-7-2011 11 ISIS running periods, MOM Rota and MICE runs in 2011 First semester Second semester

12. MICE FAC meeting 15-7-2011 12 STEP IV  in  out 1.liquid H2 absorber, empty commissioning (tracker, magnets, full DAQ and controls) 2.liquid H2 absorber, full 3.Vacuum (only He and window for trackers) 4.Solid absorbers LiH flat and wedge 5. Other solid absorbers STEP IV configurations Principle: 1.-4. will take 3 ISIS user runs This corresponds to the absorbers used for NUFACT – minimum program iff step IV can be extended without delaying step V then will do more collaboration agrees that step V should have priority.

13. MICE FAC meeting 15-7-2011 13 ISIS running Typical year consists of 5 ISIS ‘user runs’ of ~35 days each + run-ups, MP. 5 periods April 2013 to April 2014  priority to Step V installation Some additional step IV running not ruled out but lower priority Next Long Shut Down envisaged: Aug. 2014 to February 2015 new target, full EMR LiH wedge + reserve no running Step IV Installation Step IV: empty/LH2/(LHe) no absorber flat LiH

14. MICE FAC meeting 15-7-2011 14 Thinking ahead… Step V STEP V “sustainable” cooling: cooling happens in the absorbers but production of cool beam requires acceleration with RF cavities old simulation, Janot (at 88MHz) RF phase E out -E in -1- running with shutters to commission RF cavities (no beam needed) -1’- running with LH2 and RF first with no beam to check RF noise -2- running with beam with no RF and no LH2 to check optics -3- running with beam with LH2 no RF -4- running with beam with LH2 with RF lots of potential surprises! limited in optics and performance  step VI!

15. MICE FAC meeting 15-7-2011 15 Lessons learned from SS magnets 1.with cryocoolers, thermal balance is critical  special care of design and execution (i.e. constant oversight)  ample margins on coolers are necessary (5+1) 1.with several solenoids with strong coupling between them, cooling and protection of the magnet/leads against magnet quenches is essential (lead failures on SS magnet!)  Additional instrumentation and protection Many of these problems/lessons have been anticipated/corrected for the AFC and CC coils expect smoother FC running-in (Nothing absolutely certain until magnet actually works)

16. MICE FAC meeting 15-7-2011 16 Step V preparation progress specifically: RF cavities, RF power, RF controls and connections etc.. Coupling coils In short: -- RF cavities are advancing very well -- R&D on RF cavities in magnetic field is advancing well (MTA) but crucial test awaiting coupling coil -- RF distribution and controls is a large project which risks becoming critical -- coupling coils are critical

17. MICE FAC meeting 15-7-2011 17 Coupling Coil At FAC 21-01-2011: -- Concern was stated about (already wound then!) CC test at Harbin which seemed to drift hopelessly. -- This triggered DOE action  S. Gourlay in charge of all LBNL Magnets for MICE -- large increase of resources for spectrometer solenoids (first priority) -- now looking for alternate solutions

18. 18 Coupling coils review took place in Mid december. First coil has been wound at Qi Huan  Serious concerns about delays at HIT for testing cryostat. milestones given in June 2010: Complete winding of MuCool coil on mandrel ICST 9/30/10  finished in december 2010 – not bad. Complete testing of large test coil in ICST test facility ICST 11/30/10  delayed till at least September 2011…. FROM FAC 21-Jan 2011

19. MICE FAC meeting 15-7-2011 19 S. Gourlay at MICE CM30 awarded contract to wind coil and fabricate parts Welding and funding/oversight of Qi Huan contract Overall supervision

24. MICE FAC meeting 15-7-2011 24 Much thanks to DOE, LBNL and Fermilab for continuous support! S. Gourlay at MICE CM30

25. MICE FAC meeting 15-7-2011 25 Latest news on Coupling Coils (12 July 2011) Dear Alain (…) I am here at NHMFL and they have agreed to give us the cryostat. Still some hoops to jump through, but it's a better situation that it was a day ago. (…) We are meeting at Fermilab on the 27 th (July) to discuss the CC test preparations. There is still a lot of work to do to get the cost and time to install the cryostat down to a reasonable level. Regards, Steve G. immediate MILESTONES: -- completion of first cold mass (mid-July 2011) -- establish plan for CC test (August/September 2011) and review -- then establish production plan for RFCC module.

26. MICE FAC meeting 15-7-2011 26 RFCC Module Derun Li, CM30

27. MICE FAC meeting 15-7-2011 27 RF cavities 10 (8+2) cavity bodies delivered to LBNL 9 TiN coated Be windows are delivered(accepted) single cavity test module has been designed will be tested at FNAL Toshiba Ceramic windows

28. MICE FAC meeting 15-7-2011 28 RF power and infrastructure NB E. Montessinos CERN studies possibility to assemble 250 kW amplifier at CERN

29. MICE FAC meeting 15-7-2011 29 RF and power supply testing 24 June “LBNL” unit refurbished. System pushed to 1MW RF output Relatively quiet: No evidence of significant X-ray production will now continue to push towards 2MW. Next the CERN RF unit will be reassembled and tested.  2+2= 4MW Andrew Moss Forward power into load

30. MICE FAC meeting 15-7-2011 30 Much progress on layout in MICE hall

31. MICE FAC meeting 15-7-2011 31 NB considerable help from MRI grant to U. Mississippi!

32. MICE FAC meeting 15-7-2011 32 Main conclusions -- schedule We have made huge progress in re-baselining the experiment. MICE project management acquiring broader stature and efficiency The next 6-8 months will be essential For next FAC (Feb/March 2012): -- first publications of results from MICE -- new targets and EMR detector -- FC magnet delivered to RAL and working. -- LH2 system -- spectrometer solenoid 1 repaired and at full field for step V/VI: progress keeps happening. Many elements exist but it is difficult to establish a plan and schedule until the first step (testing of first CC coil) is understood. Collaboration has agreed to work towards goal of running step V in Q2 2014. -- coupling coil test underway or results -- CC plan and milestones established -- step V/VI schedule more firmly established.

33. MICE FAC meeting 15-7-2011 33 Funding and manpower issues 1.we had a very successful collaboration meeting at Oxford 6-9 July with 61 registered MICE. MICE people are very committed! 2. we are still very short of people for software and reconstruction/analysis and of competent/experienced accelerator physicists 3. the big push to put magnets (SS anc CC) back on schedule is much appreciated contribution from Fermilab will be essential 4. need to be certain about AFC#3 to be able to discuss step V/VI articulation

34. MICE FAC meeting 15-7-2011 34 Helpful funding mechanisms The EU (non-UK) partners have benefitted from the Transnational Access program, supporting visitors to come to MICE beam line to set-up or perform experiments (MICE is one) Total 200k€ over 4 years Can we find a similar mechanism to help US colleagues ?

35. MICE FAC meeting 15-7-2011 35 Common fund The MICE Common Fund has been established to help defray the costs incurred in running the experiment. The MICE Executive and Collaboration Boards review the income and expenditure on the Common Fund in standing agenda items. The Common Fund levy and the categories in which expenditure may be incurred are agreed at the Collaboration Board. -- we have made some reserve in 2010-2011 -- levy and contributions are now fairly uncontrovesial -- we agreed to proceed to replacement of all HV power supplies for detectors after power cutin Jan 2011 caused several failures (INFN in kind contribution)

36. MICE FAC meeting 15-7-2011 36 MICE MOU Originally prepared by M. Bonesini and MICE-EB, MICE experiment MOU is ready for signature. (see enclosed document) Our understanding -- INFN and STFC sign for all INFN and STFC labs -- Geneva, Sofia, Japan institutes and Muons Inc., sign one institute at a time -- need to clarify for NSF and DOE supported institutes

37. MICE FAC meeting 15-7-2011 37 FINAL COMMENTS Steady progress towards demonstration of Ionization Cooling We have already demonstrated validity of beam line principle and emittance measurements with particle detectors. Much progress on global MICE Project management (Thanks Andy!) On solid ground for running step IV in Oct. 2012 Collaboration is aiming to start step V in 2014 before long shutdown if this does not work will study possibility to skip to step VI (we should know early in 2012) Looking forward to significant cooling measurement results! Essential support from Funding Agencies has been there when needed – thank you!
