  1. MICE-UKNF Oversight CommitteeMICE Project Manager Report • Contents: • New schedule and its implications • Preparations for Steps II & III • Spectrometer solenoids • RFCC and AFC modules • Diffuser • Accommodation and facilities • Project Management and planning • Substation upgrade • Plans/conclusions Andy Nichols, STFC, 18th January 2010

  2. Present top-level MICE schedule Agreed by iMICE – only reviewed at Collaboration Meetings This version – discussed at November, 2009 ISIS moderator change July 2010 – Feb 2011 Is confirmed This is the important part Steps II &III combined Ready for February 2011 Crucial that we take Advantage of shutdown time

  3. Schedule implications • For the UK project: • Concerted effort to prepare for Steps II &III integration • Domestic infrastructure is in place • CCR cooling water is 95% done • Solenoid controls rack (DL & LBNL) has begun • CCR compressor racking is designed, material provided by INFN as CF contribution, all set to begin, material arrives next few days • But Spectrometer solenoid delivery still a major worry, more later...... • Parallel integration of Steps II & III will need more space at RAL – more later......

  4. Spectrometer solenoids • Recap: • LBNL are delivering two spectrometer solenoids • They are being manufactured by Wang NMR in Livermore, CA • They will have their fields mapped at FNAL (min eight weeks) • They are the main parts of Steps II & III • Magnet #2 suffered damaged He fill line last year • Also some HTS leads burned out • Had undergone five training quenches and reached 90% of design current • Showstopper at September, 2009 • Held review at LBNL in Late November, 2009 • Some sort of recovery plan emerged • Magnet #1 will be around two months behind #2

  5. He fill/vent lines 4th single stage CCR HTS lead area This plate needs more Cross-section * These connections under Close scrutiny * *This is where the work is

  6. Spectrometer solenoid • Review at LBNL generally went OK: • Recommended that given the circumstances, adding the fourth CCR was the right approach • Thermal FEA study of magnet must be progressed urgently • Operating margin must be evaluated accurately at cooldown – input to LHe top-up frequency • The modifications to magnet #2 should proceed as planned • Present status: • Magnet #2 (the first one we get) is in final stages of leak-checking this week • Cooldown begins 18th January • Powering tests occupy, say 25th January to 20th February* • Ship to FNAL end February* This is our ‘green light’ for Step II start in UK * AN’s interpretation only!

  7. Spectrometer solenoid • What happens at the cooldown/powering: • MICE has agreed some acceptance criteria via its Technical Board: • Must sustain design current for min 24 hours • LHe top-ups > six weeks apart (this is ‘not quite’ agreed yet) • Declaration of conformity for pressure system is completed • An as-built installation drawing and specification is completed • We hope this decision point arrives around mid-February, if all is met and field mapping goes OK, then we get magnet #2 around mid-May. • If not, we may have to face a ground-up rebuild (one year) and magnet #1 will overtake – this would be a major iMICE project re-appraisal

  8. Magnet #2 is presently dismantled Enabling more comprehensive modifications Increased cross Section in these tubes Better thermal Connections to Rad shield

  9. RFCC module Part of Step V Managed by LBNL Some problems in China RFCC • Reasonable progress also with the CC: • Problems in China are being solved slowly & carefully: • Engineering drawings of magnet will be done on time • Project management structure at HIT is being re-built • Aim is to let magnet contract to Qihuan by time of Riverside Collaboration Meeting (late March, 2010) • One set of RF cavities (four + one) have been delivered to LBNL – are being polished just now • Real delivery dates of CC magnet will become clear as order is placed - Integration/engineering needs to be driven by RAL group(s) • March 2010 is green light to begin worrying – if Qihuan contract goes wrong, iMICE needs plan B

  10. AFC & LH2 • Design work on the FC making good progress at Tesla • Some nagging doubt that the integration between the LH2 absorber and the FC is not properly understood • Is being dealt with by Technical Board – Engineering integration needs to be handled by RAL • FC delivery still promised for July/August, 2010 • Request at CM to place solid absorber(s) in FC at Step IV • Some minor design/manufacture work to accommodate, will be done by Oxford, manufacture by Warwick? • LH2: • Going well at AS scientific • R&D cryostat has performed thermally – ready to ‘mothball’ • Parts have arrived to complete the gas panel • Very clear that we have to resume work on the ventilation system during 2010 to be on time – this is a huge amount of work, will be in FY 10/11 project plan

  11. AFC & LH2 All this has to be designed & built outside R5.2. Also a big safety overhead Exp. with PPS shown this takes >1 year

  12. Diffuser • Often forgotten, but a vital part of Step II • Manufacture complete at Oxford • But a few problems being sorted out: • Pb disc transfer, making mock-up on bench to try principle • Air pressure problems – affects motor speed, should be better at RAL though with 7 bar supply • Manual control interface is working, would do in extremis for Step II operation • Automated system ready by Easter • Diffuser delivery to RAL still under review, regular Friday meetings • Not on Critical path till late Autumn 2010

  13. Accommodation & Facilities • New schedule has been built around Steps II & III being integrated more or less in parallel • Baseline WAS for series assembly in R5.2 – this looked just about possible • We do not have space there to do parallel operation safely • MICE needs at RAL: • Min 350 sqm of covered high headroom area • Single & three phase power • Water supply • Min 15 tonne crane, or authority to purchase A-frame • Discussions at RAL have not got very far • R9, R79, R12 possible candidates, R40 is excluded • Meeting fixed with Blueprint Accommodation rep for 25th January – written proposal circulated • Must get this resolved Q2/3 2010 – the UK must not be holding up the solenoids • Desperately need some constructive advice

  14. Project Management & Planning • Practical steps have been taken to reinforce the project planning and control • Guidance from UKATC • Two successful approaches to outside consultants, Magna Parva and UKAEA • Two sensible offers received • Plan to parcel up the project planning, monitoring and reporting and financial reporting into one discrete package and engage project planner for say six months– this is being actioned • Have discussed with STFC Management and within MICE, but no joy • Important that we do this now, as the engineering overhead will be increasing this CY, leaving even less time for the above – aim is to make system engineering the full-time job it needs to be

  15. Project management and planning • One (not unforseen) consequence of deleting the engineering effort (to fit the un-descoped project in the allocation) : • Integration/dimensional problems are beginning to fall between the cracks, specifically: • Survey data and layout dimensions of TOFI, TOF II & KL in beamline • Dimensional clashes between LH2 absorber and FC hardware • This was identified as a huge risk and it must be mitigated as we move to a new engineering regime • Need to reinforce the hands-on design effort from within EID at RAL • This is being written into the costed plan for FY 10/11

  16. 2MVA substation upgrade • Still a big worry • Has potential to cost up to £600K • Lead time for major components still > 1 year • As we have additional CCRs on spectrometer solenoids, risk might move from Step IV to Step III • DL group presently evaluating this • Some help for payment requested thro’ TIARA – See KL’s slides

  17. Plans/conclusions • MICE has a very clear idea of its technical objective for 10/11 • Matt Hills & Tim Hayler are preparing engineering project plan • Aim to have skeleton and milestones for 25th January • It will be the technically limited ‘ideal’ • Built around major subsystem deliverables and dates • Will request resources to allow UK to honour the iMICE schedule and NOT to hold it up

  18. Conclusions • Delivery of spectrometer solenoids is clearly our biggest technical worry • Schedule of step V similarly at risk from RFCC uncertainty in HIT/LBNL • Local engineering effort MUST be rebuilt this year • Integration/assembly space MUST be found at RAL this year • Project Management assistance plans are going ahead • The UK project has delivered what it should - the spirit is really good, despite the pressures – must keep up the momentum
