1 MICE-UKNF Oversight Committee MICE 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, 18 th January 2010

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

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

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 4

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

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 18 th January Powering tests occupy, say 25 th January to 20 th February* Ship to FNAL end February* This is our ‘green light’ for Step II start in UK * AN’s interpretation only! 6

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 7

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

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 9 RFCC module Part of Step V Managed by LBNL Some problems in China

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 10

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

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

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 25 th January – written proposal circulated Must get this resolved Q2/ – the UK must not be holding up the solenoids Desperately need some constructive advice 13

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 14

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 15

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 16

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 25 th 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 17

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 18
