STEP IV Step IV 3

Status of the Construction Step IV 4

Step IV - Status of the Construction Magnets in the Hall Spectrometer Solenoid and Focus Coil Magnets installed into position. Tracker detectors installed to the Spectrometer Solenoid Magnets Bellows for connection of each magnet have been assembled Rolling platforms for Upstream Solenoid and Focus Coil tested and operational Mechanical fit checks will be carried out before the arrival of the PRY materials. Hydrogen transfer line fit check Layout and installation of the services to the magnets and detector systems can be progressed Vacuum manifold installation making good progress. 5

Step IV - Status of the Construction Tracker Detector Installation The Tracker Detectors have been successfully installed into each Spectrometer Solenoid. Hall Probes have been installed along side the planes of the tracker. 6

Step IV - Status of the Construction West Wall and Rack Room 2 The field mitigation work to move the cooler head compressors away from the field has progressed well. The mezzanine structure at the West wall of the hall is complete. The compressor support frames are in position ready for electrical and water services Services installation has started. The civil aspects of the new rack room have been completed including fire safety and main power. Magnet power and control racks are currently being installed. 7

Step IV - Status of the Construction Partial Return Yoke (PRY) floor structures Before installation of the main structures and walls of the PRY the floor must be prepared to accept the materials. Floor support structures have been designed, manufactured and delivered to the RAL site. Floor drilling has started and construction to floor level will progress following pull out testing of the floor concrete 8

Step IV - Status of the Construction Focus Coil and R9 Lab The second Focus Coil, that will be used for Step V, is cold and condensing Helium in the cold mass. Powering tests have started, with a 50A force quench, and testing is planned to be completed by September. Magnetic Field mapping by the CERN team will be carried out after testing is completed. An extension to the MICE laboratory / Construction space in building R9 has been granted and is a substantial investment to MICE. The operational space will be doubling in area and is fully covered by an 8 tonne crane. 9 Current Extension

Cost and Schedule Step IV 10

Step IV – Cost and Schedule Schedule to completion The critical path tasks for completion of the Step IV Construction and Commissioning. Red tasks – Critical Path Orange tasks – <15 days total slack. Yellow tasks - >15 days and < 30 days total slack. Items just off of the critical path monitored to ensure any required mitigation of risk is applied. Task with high risk could push onto the critical path. Construction complete – 25 th May 2015 Commissioning complete – 3 rd August 2015 Table DOE-Review-MICE-Status.PDF 11

Operations and Data taking Step IV 14

Step IV – Operations and Data taking Operations and Data Taking Commissioning of the channel magnets can commence as soon as the North side PRY is in place. The plan for magnet commissioning is 1. Re-train all magnets separately to nominal operating currents in the most expeditious way possible with both Spectrometer Solenoid magnets being trained in a 24 hour period. Powering of the channel will take some time and effort due to the Spectrometer Solenoids requiring re-training that could require up to 15 quench runs to reach nominal operating currents. The Focus Coil remembers its training and some quenches may be experienced in stand-alone mode. 2. The nominal current for operation will be set in the Spectrometer Solenoids and then the Focus Coil will be ramped to current or quench. Calculations have shown that there will be quench back during the commissioning that will lead to the loss of all liquid Helium. Supplies of Liquid Helium will be on hand to replenish the magnets, enabling the shortest dwell time. The Focus Coil magnet has a recovery time of 48 hours and so will become the limiting factor. 15

Step IV – Operations and Data taking Operations and Data Taking The Beam line pre-commissioning – One or two Step 1 settings need to be repeated, to make sure we’re starting where we left off and to cross check against improved Monte Carlo simulations (~10k triggers) – Updated momentum settings need to be tested against matching at TOF0 with Step 1 tomography Requires new settings to take into account the Diffuser Requires DS, proton absorber, all beam line magnets, TOF0 and TOF1 ~90k triggers – Large beta (beam size) setting for Tracker commissioning without magnetic field requires testing ~10k triggers The Beam line commissioning – Necessary to test the MICE Muon Beam matching to the MICE Cooling Channel – Requires DS, proton absorber, all beam line magnets, TOF0 and TOF1, Diffuser and commissioned Upstream Tracker (requires B field in SSU) – Requires beta, alpha and emittance reconstruction at all 5 Tracker planes to test the behaviour of the beam settings required for the physics grid requiring ~10k triggers for each grid point – Most likely will need to be repeated Commissioning shift requirements (1 shift = 8 hours), including contingency – Beam line pre-commissioning – 8 shifts – Beam Line Commissioning – 15 shifts – MICE Channel Commissioning – 21 shifts – During each commissioning phase the data taken will be used to exercise the data pipeline in preparation for the data taking campaign. 16

Step IV – Operations and Data taking Operations and Data Taking Physics Run plan – 3 Emittance x 3 Momentum x 5 Beta Function matrix – Empty / LH2 / LiH Absorbers (if possible the wedge) Solid Absorber changes during shutdown of ISIS – Flip / Solenoid mode – Positive and Negative beams – MICE target will run at 0.8Hz and at 4 V.ms beam loss – From the 3x3x5 matrix each Mode / Absorber / Polarity will require 45 measurements – A reduced data taking regime will be used for the Negative beam polarity operation 17 ISIS User run schedule – Current schedule for construction complete precludes the first user run. –User run during Jan – Mar 16 to Target station 2 Data period – For one set of measurements

Risk 29

Risk - Retirement Focus Coil remembers its training – After thermal cycle the current attained was at the level last tested. – Returned to operational current after Solenoid mode / Flip mode change – During hall commissioning the expectance is for a return to operational current With the current review this risk is retired – Removal of the Step VI arrangement of the experiment – The project is re-focusing on achieving early delivery and so completion of the project. 30

Risk - New Resourcing –Technical effort at FNAL for build of the RFCC not available due to external project pressures – Loss of expert knowledge in the event of early project termination – Reduced staffing for operations in the event of early project termination Senior Management – Management of the project leave / re-deployed – Direction and drive unfocused Late Delivery – UK were to advance as far as reasonably practicable the schedule of installation – If delays to equipment delivery were RFCC 4 months(7 flat), South PRY 5 months(8 flat) and North PRY 6 months(9 flat) – Standing army costs 31

Summary 32

Summary Progress to the completion of the installation of Step IV is good – All magnets and detector systems required for the arrangement are in the experimental hall – Magnetic field mitigation strategies are now solid, West wall, Rack room 2 and PRY – Schedule delay mitigation is now being put in place for the PRY delivery – Operational and data taking management in place and active – Construction complete 25 th May 2015 From the schedule and funding analysis shown for Step V it will NOT be possible to integrate the RFCC as soon as it is ready, 24 th January – Advanced funding would complete installation 5 th February 2018 – Flat funding would complete installation 21 st May 2018 – Additional build-up area and storage in the R9 laboratory has been arranged. – Advanced funding for capital equipment purchase and storage in preparation for installation would be beneficial. – Delivery schedules for flat funding purchases do not have a detrimental effect on the installation due to the length of de- commissioning and preparation required. – The driving factor is the date at which the Step IV data taking campaign is completed. Advanced funding scenario (Plan A); total cost £15.3M (inc risk) Flat funding scenario (Plan B); total cost £16.2M (inc risk) Stop at Step IV; total to complete £7.1M (inc risk) With reduced FNAL technical effort / management focus there is a risk of the RFCC installation driving the critical path and creating a standing army; not just in the UK but also with European and Japanese collaborators. 33
