Present top-level MICE scheduleAgreed by iMICE – only reviewed at Collaboration MeetingsThis version – discussed at November, 2009
This is the important partSteps II &III combinedReady for February 2011
ISIS moderator changeJuly 2010 – Feb 2011Is confirmed
Crucial that we takeAdvantage of shutdowntime
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......3
Spectrometer solenoidsRecap:
• 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 #24

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 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!

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

Magnet #2 is presently dismantledEnabling more comprehensive modifications
Better thermal Connections toRad shield
Increased crossSection 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

RFCC modulePart of Step VManaged by LBNLSome 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

AFC & LH2
11
All this has to be designed & built outside R5.2.Also a big safety overheadExp. 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
2010

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
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 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
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
