MICE WBS

MICE WBSWeekly MICE Hall planning meetings. Essentially a 2 week look-aheadWeekly MICE Schedule planning meetings, concentratingOn the longer term plus planning for the forthcomingweekend

MICE TargetPast problems with bearing wear.

Now using DLC (Diamond Like Carbon or Diamolith).It is a Plasma Enhanced Chemical Vapour Deposition (PECVD) process that deposits a material layer that is about 3-5um thick.

At present only got one, top bearing, DLC coated and the target shaft. >2M operations without wear

MICE TargetProblems that we needed to solve for target installation into ISIS: Removal of the old target.Need to demonstrate procedureCan we use short Nov. shutdown?Approval to put the new target into ISIS.YES! MICE procedure accepted by ISISSome conditionsInfrastructure ready for target in ISIS.Two targets needed, test vessel, remote handling, fibre optics, control cables. Bottom bearings need coating

Target: schedule:

Target: schedule continued:Now planned with DL controls group: needs to be updated.

Upstream beamlineRequire to complete/install:AlignmentPROBLEM need to lower magnet standsVacuum vesselsPROBLEM with Dipole 1Need to move vacuum boxServices:VacuumWaterElectricalAgreement with M.Krendler (ISIS):Milestone (deadline) for completion of above20Jan08: the end of the Christmas shutdownWorking with individuals to complete as much as possible before minor maintenance periodNext three/four weeksNext opportunity November minor maintenanceBut most people at the limit of their annual dose. We should get the supplies connected.

Upstream beam line: power supplies:Rack being installed now:Required removal of treads of north-east stair casePower-supply units and cabling to follow

Upstream beam line: Xmas work

DSA (Decay Solenoid Area)June: Hole to synchrotron vault, North wall in placeOctober: Shielding to synchrotron, W & S walls of iron & concrete built. PPS doors installed. Plinth built, additional shielding on plinth, wall painted. Dipole 2 installed, downstream Q35 baseplate in position.

View over DSA into MICE HallJune: Most of Hall cleared, some shieldingOctober: Decay Solenoid Area civil engineering almost complete. Roof still to be designed & fitted.Can we remove North Wall?On-going discussions.Looks possible if we can replace sandbags with steel shot. More news from Willie & Andy?

Delay SolenoidSo far, major leak has been found and repaired BUT at the cost of considerable damage to MLI. Need 2? weeks of skilled effort. Matt is developing a plan to complete this task. Cold mass still to be aligned and tie rods re-tensioned

Linde cryogenicsAfter DSA completed, support installed for buffer tank, below which is control plant.Transfer line carries cold helium gas to and from either Test Cap or decay solenoid

Linde cryogenicsHelium transfer line installed and connected to Test Cap. Most of the scaffolding now removed.After cool-down and other tests, transfer line will be connected to PSI Decay SolenoidInstallation completed ahead of scheduleCommissioning started and hope to finish 25th or even 18th Nov.

Linde Schedule as of 9th Oct

Q35 Refurbishment & InstallationFirst 3 magnets finished this week. Test in R6. One technician has left. Replacement being sought.Need to increase # people with crane licences Trial assembly of magnet support on baseplate completeUpstream baseplate (Q4-Q6) in DSA has been aligned & levelled (grouted today?)Downstream plate ready with all components

Down-stream beam-line:Quadrupole triplets:First quad triplet refurbished:Magnetic testing to start next weekTrial build of quad stand completeQuadrupole triplets cont.:Refurbishment of remaining quads:Goal: complete by 20Jan08Services being installed now

Q35 refurbishment: schedule:Focus on Q35 work has paid off, but:Magnetic testing will start 01Nov07:Developing schedule with Paul Flower now he has returned from CERNHave had one more coil failure: potential issue:Have expedited testing of remaining coilsContinuing refurbishmentNeed to consider options when it is known if any more coils have failed

MICE Local Control Room (MLCR)Rack bases delivered DPM & floor screed completedNetwork rack delivered this week?PPS rack, populated and tested (@ DL) also delivered this week?Remaining racks the following week.Air conditioning and power to start soon. Estimated to take three weeks so complete by 9th November.Roof has been fitted & plastered this weekNetwork connection cabling installed.Connection to RAL site to start as soon as the racks have been delivered from DL.A wireless access point to be set up as soon as possible.Further wiring into the hall to follow. Too much civil still going on to start too early.

MLCR timescale

Reviews: beam line

Spectrometer and instrumentation:Spectrometer solenoid:First spectrometer solenoid:Coils almost completeExpect delivery to FNAL for magnetic field mapping in DecemberSecond spectrometer solenoid:Fabrication advancedExpect delivery ~2 months after firstCKov:Two modules:Most of the first (CKova) at RALSecond module under construction in MississippiTOF:TOF0 and TOF1 under construction in Milan:Expected at RAL 15th November for cosmic ray testsCalorimeter:Pre-sampler (KL): under construction in RomeExpected at RAL 15th November for cosmic ray testsSandwich calorimeter:Design complete, prototype under construction

Spectrometer and instrumentation:First full tracker being manufactured:Final step in QA chain (station acceptance rig) now in full production modeSpace frame being builtSupport frame in manufactureElectronics:Being prepared for shipping in FNALWill be shipped this week or next weekcontinued

Cosmic-ray integration test:Will start 12Nov07:Will include:CKov, Tracker, ToF, and KL (pre-sampler)

Other IssuesXmas shutdownWell planned, WBS manager (Tim Hayler)Already VERY tight. Every other task that is delayed now moves into this schedule.False floor and plinth in main hallFalse floor should be completed in time for decay solenoid to move for cool-down testsOther newsWater chiller order placed. Rolling platform FDR completed, PRR due. Magnetic shield. South wall drgs. complete. North wall, design almost complete. Aim to have contracts placed well before end of this FY.Quotes for Cyclotron steel being sought

Phase I instrumentation:Cosmic integration test: will start 12Nov07Craig MacWaters coordinating testWill use R8:3-phase, water, etc. being plannedUnforeseen expense (likely small, but being estimated)Components:Tracker:Station acceptance QA rig now running at ImperialStation 5 (first final station) has been QAed: results OK;Decide today 15:30(?): proceed with QA or more studies required on station 5Space frame in manufactureCosmic stand signed off for manufacture (?)TOF:Expected to arrive 15Nov07KL:Expected to arrive 15Nov07CKovaAlready at RAL, needs to be assembledDAQAlready at RAL, needs to be moved to R8

Cooling channel components:RFCC module:CC design and fabrication done in collaboration by LBNL and ICST in Harbin, Chinaconductor ready to orderRF cavities will be similar to existing MuCool prototypefabrication to get under way shortlyMuCool 201 MHz cavity R&D:Without field now have 19 MV/M
