  1. UKNF/MICE Oversight CommitteeOpen sessionIntegration of the MICE project • Background & local history • Progress since 2007 • Schedule & planning considerations • Re-defining the UK project • Electrical engineering • Future plans Andy Nichols, Tim Hayler, STFC 22nd June, 2010

  2. ......Circa 2007 But this is what we’re aiming for...........>> Circa 1963......

  3. ........Installation of MICE Step VI in R5.2

  4. Progress since 2007 • Starting at the bottom: • Demolish old floor • Install new false floor • Acts as base for whole cooling channel • Conventional construction, but has to be reasonably flat & true • Able to withstand 50 tonne quench force • And, most important, able to be fiddled with extensively in future!

  5. Progress since 2007 • Next level: • Provision of baseplates for spectrometers 1 & 2 • Accurate and repeatable locations for detectors • Able to withdraw from beamline for servicing • Magnets move on airpads • Non-magnetic construction • Able to react 50 tonne quench force

  6. Progress since 2007 • Provision of two magnetic shield walls • Act as return yoke for cooling channel • Protect ISIS Linac and MICE control room from stray fields • 150 tonnes of magnet iron, delivered on time by UK industry • And supporting framework/galleries

  7. Progress since 2007 • Have also done much routine but essential infrastructure work: • Provision of CCR cooling water system • Uprated compressed air system • Provide air conditioning • Uprated the domestic power, lighting & fire detection • Compliance of R5.2 to all safety & local rules • Extract fans • Accommodation for 28 CCR compressors and services • General civil engineering work • Much help here from Building Projects Group (BPG) and ISIS at RAL • Formal handover from BPG 16th June – many thanks indeed

  8. MICE compressed air system Behind R5.1 70 MeV plant room Guaranteed line 5.5bar (actual 6.5 - 7.2psi) MICE Trench

  9. Schedule and planning considerations • All this brings us to June 2010: • Have been ready for Steps II &III for a few months • Were geared towards Step II start in Mid-May, 2010 • Won’t happen till later in 2011, • What to do........?

  10. Re-defining the UK project • Steps II & III are delayed for at least one year • UK installation team and infrastructure construction were very carefully geared towards spectrometer solenoid #1 arriving at May 15th • We want to hold the installation team together, so: • Advance work on the LH2 system - see also Matt’s talk • Vent system • Civil engineering • Pipe/valve & gas panel work • RF power work • Design of waveguide/power/cooling infrastructure, placement of amplifiers • ‘Hands on’ work at DL with RAL team – second LBNL amplifier • Both RF & LH2 projects contain open issues – better to find out early

  11. LH2 external infrastructure All this has to be designed & built outside R5.2.

  12. RF Power • Two RF amplifiers from LBNL are being reconditioned at DL • One is complete, the other is waiting • Plan to deploy some of existing team on second amplifier • Important to do this early while we have time • Led by Daresbury Lab • Very beneficial DL/RAL relationship • RF amplifiers quite big, 4m high and 1 tonne – we have to fit four of them in a very confined space

  13. Need to fit all this........ .....Under here!

  14. Electrical Engineering • Also led by Daresbury Lab: • All detector wiring and cabling • Electrical services in general • Complete implementation of PPS (Personnel Protection System) • Contribution to electrical substation upgrade project • Conventional and S/C magnet power supplies • Cooling Channel controls project • Target power, readout & controls • Major contribution from BPG: • Power for heating, lighting • Implementation of fire detection • A/C power • Electrical substation upgrade project

  15. Electrical substation progressThe problem: • The electrical supply in R5.2, the MICE Hall, needs to be upgraded to 2MVA, certainly to run at Step IV and probably at Step III • Most of the power is required for CCR compressors, latest predictions are (5+1)x2 for spectrometer solenoids and 3x2 for coupling coils • The present layout in R5.2 gives 1.25MVA and is based on fifty-year old equipment that has not been used to full capacity for many years • The ingoing cable to R5.2 has adequate capacity and does not require any work • Historically, this has been treated as a host-lab contribution and has never appeared MICE’s costed plan • But we understand the need for a discussion

  16. Point at which we’re In trouble Present power Rating (1.25MVA) STEP I

  17. What all the fuss is about: Cryomech two-stage Closed Cycle Refrigerator Present configuration of Spectrometer sol 3 x 2 stage CCR + 1 single stage Proposed configuration: 4 (or 5) 2 stage CCR + 1 single stage Coupling magnet will likely need Three instead of two 2-stage CCRs MICE something of a pioneer here Not usual to cool large magnets with CCRs

  18. Electrical substation • Four technically viable solutions have been identified by BPG and DL • Varying degrees of cost/technical capability • We have been asked to follow up the two cheapest options • Meet again with STFC Management on 8th July • Hope to know which version then • Lead time is dominated by major components (around one year), but we also need to add design & installation time • So if we begin now, might just be OK for Step III in late 2011

  19. Future Plans • Between now and 2014, MICE has to successfully build and install several large and complex subsystems, for example: • Two spectrometers • Three absorber-focus coils • Two RF-coupling coil magnets • And all their services and ancillaries • In a very confined space to a reasonable degree of accuracy • Also have to accommodate several different engineering ‘cultures’ and standards • Have demonstrated that a more rigorous engineering approach pays dividends – eg, the MICE target • Now want to read that across to the other subsystems • Easier said than done.......

  20. Future plans • So we’re changing the emphasis slightly, from infrastructure and surroundings to the subsystems and interfaces • Top level assembly now successfully driven by one (large!) Solid Edge CAD assembly • RAL engineering team is being reinforced • Full time integration engineer is appointed • Am now working on support for him • Monthly MICE Technical Board will be forum for integration issues • Integration activity will be centralised at RAL - important • Discussions just beginning with subsystem owners to encourage information flow
