2. MICE RLSR – 13Nov2013 Alain Blondel 2 OVERVIEW Recommendation 1. Create a living, accessible and regularly updated one-page "dashboard" summary of milestone achievements demonstrating the evolving status of deliverables (eg magnets), initially focusing on Step IV, as soon as possible. (a dynamic presentation of the data normally contained in Gail’s Milestone table after selection of most significant milestones)  Roy Preece Recommendation 2. Produce a one-page specification for the operation of the MICE International Project Office and present at the next MPB meeting This was drafted by Andy Nichols, pending full approval by CB.  Ken Long Conclusions and recommandations from MPB in May 2013(I) also written up in the written report to MPB

3. MICE RLSR – 13Nov2013 Alain Blondel 3 SUPERCONDUCTING MAGNETS Recommendation 3. Investigate the potential reasons for the slow and unusual training of Spectrometer Solenoid 2 (and Focusing Coil 1). Check the protocols (eg travelers) for the Spectrometer Solenoids and Focusing Coils, to establish the level of quality assurance and to seek explanations for slow training. Present results at the next MPB meeting. We dont have a predictive understanding of the behaviour of the magnets but we have collected the data and made a number of tests.  John Cobb Recommendation 4. Re-evaluate the possibility of proximity shielding (partial yoke) that takes into account the detailed situation of the present infrastructure in the MICE hall and present a plan for future work at the mitigation shielding review at RAL in August/September. The magnetic mitigation group did this.  Holger Witte RF SYSTEMS Recommendation 5. Prepare a plan to test a prototype Low Level RF system with the RF Coupling Coil at the Fermilab MTA, and present the plan at the next MPB meeting. We have decided not to do this. Conclusions and recommandations of MPB (II)

4. MICE RLSR – 13Nov2013 Alain Blondel 4 COMMISSIONING, CONTROLS & OPERATIONS Recommendation 6. Present an integrated plan for all aspects of the control system at the next MPB meeting. (Controls team is preparing this. Very much work in progress!)  Pierrick Hanlet Recommendation 7. Present the requirements and design of the MICE timing system at the next MPB meeting, with particular emphasis on absolute calibration by particle arrival phase measurement. Work ongoing, in collaboration between DAQ expert and RF group at DL.  Kevin Ronald Recommendation 8. Explore the potential to achieve synergistic economies of scale in the maintenance and operation of the liquid hydrogen system by working with the ISIS moderator cryogenics team, and present at the next MPB meeting.  Ken Long Recommendation 9. Develop an on-site support plan for day-today operations, maintenance and repair of the MICE hardware, and present at the next MPB meeting. (  MICE operations group)  Ken Long Conclusions and recommandations of MPB (III)

7. MICE RLSR – 13Nov2013 Alain Blondel 7 A lot has happened in the last few months! Have arrived at RAL: -- RF amplifier -- 11 crates of RF equipement from U-Miss -- The EMR and all its kit -- the Upstream Spectrometer Solenoid (USS) (aka SS2) -- the AFC2 + we have carried out the EMR run with beautiful results  (and with all available detectors included in the DAQ) + we have decided on the field mitigation strategy and passed a review. + our paper on emittance measurement of the MICE beam with TOFs is published. Avatars: -- Decay solenoid had a burned LTS lead during test of new QPS  fix by Apr14 -- Downstream Spectrometer Solenoid had a few issues  delivery in May14 -- Coupling Coil test had 2: He leak in June, thermal insulation needs redone. Coupling coil test  Q1 2014.

22. MICE Field Mitigation Review 23-09-2013 Alain Blondel 22 HOWEVER... a lot will depend on what the magnets can deliver we will know only when the beamline is assembled the Upstream Spectrometer Solenoid USS (SS2) was tested and passed for all requested ‘design’ curents. AFC1 passed for the maximum requested current in «solenoid mode», but not in «flip mode» where the ‘nominal setting’ (center of 3x3 matrix) is barely achieved. Situation may be worse (or better) when all magnet are powered in step IV configuration.

24. MICE Field Mitigation Review 23-09-2013 Alain Blondel MICE Note 434

25. MICE RLSR – 13Nov2013 Alain Blondel 25 Conclusions 1. MICE is in happy shape, looking forward to step IV! -- With new Spokesperson, Project Manager, Project Engineer -- Several important milestones have been passed 2. Decision was made to implement the Partial Return Yoke -- schedule will be more predictable 3. Next large uncertainty concerns the performance of the magnets when powered all together -- we are preparing to adapt to peformance being lower than design but above the ‘nominal point’. (modify beta function at absorber) -- however if performance were below the ‘nominal point’ MICE would force more drastic questionning to know how to go forward with the experiment. 4. Preparations for STEP V/VI are progressing
