MICE Video Coference Project Manager Report

1. MICE Video CoferenceProject Manager Report • Contents: • Technical organisation of project • Target and upstream beamline • Muon beamline • Infrastructure and Phase One • Steps towards Phase Two • Summary Andy Nichols, STFC, 24th April 2008

2. Technical Organisation • New Management team has been in place for six months: • PM/Technical Co-ordinator – Andy Nichols • Hall Manger/Principal Contractor – Willie Spensley • Hall Foreman – Ash Jamdgni • ISIS liaison – Chris Rogers • MICE Operations Manager – rolling monthly post, currently Malcolm Ellis • And we have a stable group of well-motivated technicians • With much valuable help from Richard Apsimon and Paul Flower • But Richard & Paul have now retired: • Internal (RAL) vacancy for PM approved, but no candidates • Nominated MICE radiation safety person also required

3. Target & Upstream Beamline • Target is now in ISIS, but there are still problems: • Agreed last year with ISIS to have on-line (in ISIS) and off-line (in R76) identical targets, with the off-line run in advance, but • Problems with actuator coils have prevented the off-line target from running. These problems are being understood with valuable input from DL • Two (+ One spare) targets are being made, complete mid-May • Currently, target running is limited to machine physics periods in ISIS because of above problems, but we are preparing a case to operate target during user runs • Found we need to dip an extra 5mm(??) into the beam – thought not difficult to arrange, by mechanical means only, work it out Monday • Good news is that the current target behaves itself very well • Still to do: • Complete and test both targets • Target planning meeting with ISIS on Monday • Install both in ISIS and R76 • Integrate the target operation with the overall MICE controls

4. Target & Upstream Beamline • Upstream is effectively complete: • Re-worked magnet stands installed • Vacuum chambers installed and leak-tested • Magnets aligned • New target vessel with correct beam window position • Problems with Q1,2,3 power supplies, now fixed and awaiting soak test, aim for short access if possible, or wait May shutdown

5. Muon Beamline • PSI (Decay solenoid • But we go ahead with cold test on 21st April 2008, expected to take 14 days • Currently a few leaks to fix, transfer line is at atmosphere – difficult to explain. • Some dismantling of cable trays needed to access unions etc – uncomfortable, but not impossible • 24 hour cover needed over next two weeks – unskilled babysitting only, with phone access to experts – volunteers welcome! • Still to do: • Complete ‘magnet – on’ lights • Complete cold test and test quench protection • Minor shielding additions • Compile safety documentation and implement safety procedure

6. Muon Beamline • D2, Q4,5,6 installation is essentially complete • Minor work on water connections needed (May shutdown), otherwise ready to go. • cKOV chambers – were successfully installed during March and now operational • TOF0 – not installed yet – problems at Milan with PM tubes, being understood, likely shipment to RAL is now early to mid-May – this is a cause for concern.

7. Infrastructure and Phase One • Six months ago the Infrastructure project was not well understood: • New WP1 manager – has defined sub-workpackages: • Magnetic shield walls (North & South) • False floor design & M/F • Remove existing concrete floor • Excavate part of ISIS mound (around LH2 vents) • Electrical & mechanical services • Local control room • Ventilation (air conditioning) • DSA roof and fencing • Rolling platforms • Good progress being made on all fronts • Due to the unforseen complexity, we missed original March ’08 finish date – has been agreed with OsC to finish July • Staff over-run costs and magnetic shield wall costs largely account for overspend

8. Infrastructure & Phase One • Magnetic shield wall: • Separated into support structure and shield plates • Support structures: 30% off site fabrication complete, plan to start on-site early May • Shield plates – successful OJEU tender in February – contract with Charles Day steels, Sheffield – delivery in phased 35 tonne loads, first one early-mid May • No real problems!

9. Infrastructure & Phase One • False floor design: • The base for phase Two: • Metallic framework to raise existing lowered floor • Provide level support and mounting for cooling channel elements • Resist quench and gravitational loads • Interface with the (as yet un-designed) RF infrastructure • Status: • Baseline design is done • Magnetic modelling is in process (critical input to above and now a cause for concern) • Aim for design complete early May.

10. Infrastructure & Phase One • Concrete floor removal: • It’s finished ahead of schedule, but: • Structural weakness discovered in surrounding concrete, on which shield wall is supported • Completely unforseen, core samples are currently with structural consultant, most pessimistc outcome is: • Excavate the area, re-pour concrete and add re-inforcement • Aim to do in parallel with other work, minimal delay, but unknown cost implication • Latest news: it’s OK! But written confirmation from structural engineer awaited

11. Infrastructure & Phase One • ISIS Mound excavation: • Part of the mound behind MICE hall has to be excavated to accommodate the LH2 vent system, another thing we ignored! • Problems: • The earth is unstable, cannot dig without re-inforcing • No access for equipment • Craning material/equipment over ISIS control room is precluded • Hand digging likely => good weather • We are interfering with ISIS shielding – will be subject to radiation survey • Difficult, but the right people are working on it; likely solution is a pre-cast sectional concrete barrier – sanction from ISIS RPA on this basis has been obtained • But we are unlikely to finish before August – problem as we overrun revised phase one finish date

12. Infrastructure & Phase One • Electrical & mechanical services: • Fairly uneventful, work is now reasonably understood • Supervision of contractors suffered due to sick leave and overload in Building Projects Group • Steve Griffiths of DL has stepped in to help – presence by his group at RAL three days a week • Which is good, on target to complete the phase one work on time. • Local control room is now habitable and in use Now Then

13. Infrastructure & Phase One • Ventilation & Air conditioning • 400KW (eventually) of heat needs to be removed • Five A/C units have been delivered • Some pre-wiring has been done • Final wiring and installation cannot take place till shield walls and mezzanines are installed – off critical path • DSA roof and fencing: • Part of safety system, fencing around and one-way escape route from DSA, also partial roof • Design done, drawings signed off – meeting to finalise works order 21st April – part of May shutdown – Drawings now signed off

14. Infrastructure & Phase One • Rolling platforms: • Modular platforms to support beamline elements and allow withdrawal • Move on air pads • Design done • Successful tender exercise, contract placed with ESE in Poole • First platforms (for steps 1,2,3) delivered in May • Air pads, controls and ancillary stuff also on order • Not critical path

15. Steps towards phase two • Revised step one has been agreed by MICE EB • It’s just the KL, TOF1, fixed and moving beamstops Can take place on existing raised floor Depends on arrival of KL & TOFs in early May Must finalise sliding beamstop baseline Very soon – planned for TBmeeting, but We have a problem…………… Careful planning needed to allow concurrent Work on shield wall supports – we have the space and L.Tortora has agreed if fence and stay/clear are provided

16. Steps towards Phase Two ……..the sliding beamstop requirements are now complex After consulting with RPA – completion before June is impossible Due to delivery of scissor lift and necessarily complicated shielding design We will have to make an interim version: Beam aperture tube and steel shot in DSA Then manually craned concrete and steel blocks (which we have)

17. Steps towards Phase Two • Permission granted for focus coils order, (two plus option for one) • Kick-off meeting with Tesla scheduled for 18th April • Detailed schedule, design and manufacturing plan should emerge then • Also mechanical/electrical/cryogenic interfaces • Latest news: contract has been signed • UK Phase Two WBS, infrastructure plan, bottom-up staff & capital estimates are complete • Phase Two WP managers have been circulated for their plans – much useful input to the above

18. Summary • Target has enabled MICE to take data, but there are still some problems • Upstream quads and dipole are essentially complete • Mechanical integration of solenoid went very smoothly, still some cryogenic problems, but nothing we don’t understand • Downstream quads essentially complete • The infrastructure project is now well understood and good progress being made • Magnetic modelling information for false floor is urgently required • New Project Management structure is established • Placement of AFC contract a major positive step • Content of Phase Two WBS must not be under-estimated • Downstream beamline elements are generally progressing well • Delivery of TOFs to RAL is causing concern
