1 MICE Video Coference Project 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 21 st 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 Then Now

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 21 st 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 TB meeting, 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 18 th 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
