  1. Project report

  2. Status: MICE Muon Beam • Target: • Target presently installed ‘in-operative’: • Optical connections removed (why?) • Implies realignment/set-up • Jacking motor drive/control not implemented • Implies remove target as soon as possible: • To recover some components if possible • To prepare for installation of final target • Plan being prepared • Copper and optical cables procured: • Need to be installed when available • Plan being prepared • Signiticant progress on bearings: • Brass and copper bearings show less wear • Diamond-like carbon on ceramic to be tested • Working towards documented solution to be presented to ISIS • Targets: • Prepare new target installation in November short shutdown

  3. Status: MICE Muon Beam • Upstream beam line (Krendler et al): • Quad triplet and dipole 1 installed • Services (power and water) yet to be connected • Issues: • Vacuum box for D1: • Possible need to reposition (to be studied) • Vacuum box for Q1—3: • Too big! (2mm in diameter) • New box will be procured (Krendler) and installed • Magnetic testing (Tilley) • Dipole and all quads tested (implies water connection and power) and fields measured prior to installation • All magnets checked out OK

  4. Status: MICE Muon Beam • PSI solenoid (Courthold et al.): • Vacuum leak traced: • ‘Beam degrader’ was located in bore. Had been cooled using LHe. When degrader was removed, pipes had been cut and not re-sealed, no information passed on • W. Gloor (PSI) provided rails to draw out cold mass, visitted RAL to work with local team • Circuits tested under pressure and under vacuum • Major milestone! • But, many tests still to do

  5. Status: MICE Muon Beam • Linde refrigerator (Courthold et al): • Intend to start installation commissioning 20Aug07 • Many hurdles overcome: • Bureaucratic • CDM/certification issues now final step: • Propose to meet with Jonathan Carkeet

  6. Status: MICE Muon Beam • Plinth (Jones et al): • Steel boxes installed and aligned • Concrete fill complete • Plates installed on top, levelled • Grouting complete • First layer of rail system installed and aligned • Next steps on installation awaits completion of shielding walls

  7. Status: MICE Muon Beam • Survey: • Synchrotron-side survey complete (Loughrie) • MICE Hall side survey partially complete (Jones, Croxford): • Beam-line out of synchrtron, through PSI solenoid, D2, and into Hall surveyed • Preliminary survey of D2 rails performed: • Need more detailed survey to define shimming • Survey of plinth rail system needed as it is installed • Required equipment on ‘the right side of the shielding’!

  8. Status: MICE Muon Beam • Dipole 2 (Jones et al): • Rail system installed • Bogey installed on rails • D2 installed on bogey in ‘out’ position • Issues: • Require to design/implement movement system • Services (power/water) to be installed • Magnetic measurements to be made

  9. Status: MICE Muon Beam • Q35 refurbishment (for Q4—Q9) (Eammon, Cyril): • First Q35 reassembled • Final steps in re-fitting of water manifold being carried out now • Schedule: • To be revised now that first complete magnet is available

  10. Status: MICE Muon Beam • Shielding: • Removable north wall: • Complete • South wall steel and bracing • Complete • Synchtron (east) wall concrete infill • Complete • South wall concrete block/fill wall • In progress • Down stream (west) wall steel • In progress • Down stream (west) concrete • Reinforced concrete blocks for final build on order • Annoying, but no real impact on programme • Temporary concrete blocks available and will be installed this week (perhaps at the weekend)

  11. Status: MICE Hall • House keeping: • CMS equipment (magnet etc) removed • CMS cabin demolished • Q4s removed • Tidying: • Much tidying done, still quite a lot more to do! • Infrastructure and services: • Water (Governs): • Preparing to procure system and install to be available 01Dec07 • Air: • Reconsider heat load into air: • Options to air-condition available • Magnetic shielding • Final step: specification of permittivity • Floor plates etc. • Designs available, need to push through • Urgent to move on the design/implementation as soon as shielding build complete

  12. Status: MICE instrumentation • Upstream PId: • TOF0/1: on track for delivery to RAL ~Nov • CKOV: Parts of first module now in R12 • Mirror production at FNAL • Slight delay • Second module to be shipped • Preparing to take part in cosmic test with tracker starting September/October • Spectrometer solenoid: • Fabrication: steady progress • Expect first solenoid at RAL in February • Tracker: • Further 2 VLPC cassettes released to MICE by D0 • Important milestone, now have 75% of what we need • Electronics: • VLSB: some uncertainty owing to internal re-organisation at FNAL • Probably OK, already enough boards for cosmic test • Firmware development: satisfactory progress • Mechanical: • Some delay, casualty of pressure on beam line (Barber) • Station acceptance being brought up at Imperial • All stations for both trackers available • To do: • Detailing of final supports • Completion of model, including diffuser • Cabling to be prepared at FNAL • Cosmic rig design • Able to move this up the priority list now • Downstream PId: • TOF2, CAL • Need to understand how these will be provided

  13. Status: RF, LH2, FCs, RFCC • RF: • Power out of 250kW amplifier in June • Plan for power out of MW amplify by Christmas • Need to check • LH2: • Cryostat being procured • Issues to be address: • Minor modifications to design to be reviewed • Safety to be reviewed • Papers in preparations • TB will take appropriate action • FC modules: • Tender process underway: • Plan to close on schedule in September • RFCC: • Sorry, assumed MZ would make comments • C&S: • First round of preparation done at June collaboration meeting • Need now to combine schedules/cost estimates • Need to make progress on this

  14. Schedules: • Casualty of disc crash! • Apologies • Preliminary schedule for December shutdown prepared: • Critical • Schedule for work August—December in preparation • Again critical • Schedule for completion of Phase I and Phase II • Urgent • Will pick this up asap
