MICE phase I - Project Status • Richard Apsimon (Project Manager) & • Andy Nichols (Technical Coordinator) • … with considerable help from Ken Long! • MICE Video Conference 1st Nov 2007
Contents • MICE WBS • MICE target news • Upstream beamline • DSA & the Decay Solenoid • Linde refrigeration installation & commissioning • Q35 Refurbishment, testing & installation • MICE LCR • Other issues
MICE WBS Weekly MICE Hall planning meetings. Essentially a 2 week look-ahead Weekly MICE Schedule planning meetings, concentrating On the longer term plus planning for the forthcoming weekend
MICE Target • Past 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 Target • Problems that we needed to solve for target installation into ISIS: • Removal of the old target. • Need to demonstrate procedure • Can we use short Nov. shutdown? • Approval to put the new target into ISIS. • YES! MICE procedure accepted by ISIS • Some conditions • Infrastructure ready for target in ISIS. • Two targets needed, test vessel, remote handling, fibre optics, control cables. Bottom bearings need coating
Target: schedule continued: Now planned with DL controls group: needs to be updated.
Upstream beamline • Require to complete/install: • Alignment • PROBLEM – need to lower magnet stands • Vacuum vessels • PROBLEM with Dipole 1 • Need to move vacuum box • Services: • Vacuum • Water • Electrical • Agreement with M.Krendler (ISIS): • Milestone (deadline) for completion of above • 20Jan08: the end of the Christmas shutdown • Working with individuals to complete as much as possible before ‘minor maintenance’ period • Next three/four weeks • Next opportunity November ‘minor maintenance’ • But 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 case • Power-supply units and cabling to follow
DSA (Decay Solenoid Area) • June: Hole to synchrotron vault, North wall in place • October: 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 Hall • June: Most of Hall cleared, some shielding • October: 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 Solenoid • So 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 cryogenics • After 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 cryogenics • Helium 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 Solenoid • Installation completed ahead of schedule • Commissioning started and hope to finish 25th or even 18th Nov.
Q35 Refurbishment & Installation • First 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 complete • Upstream 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 week • Trial build of quad stand complete • Quadrupole triplets cont.: • Refurbishment of remaining quads: • Goal: complete by 20Jan08 • Services 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 CERN • Have had one more coil failure: potential issue: • Have expedited testing of remaining coils • Continuing refurbishment • Need to consider options when it is known if any more coils have failed
MICE Local Control Room (MLCR) • Rack bases delivered • DPM & floor screed completed • Network 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 week • Network 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.
Spectrometer and instrumentation: • Spectrometer solenoid: • First spectrometer solenoid: • Coils almost complete • Expect delivery to FNAL for magnetic field mapping in December • Second spectrometer solenoid: • Fabrication advanced • Expect delivery ~2 months after first • CKov: • Two modules: • Most of the first (CKova) at RAL • Second module under construction in Mississippi • TOF: • TOF0 and TOF1 under construction in Milan: • Expected at RAL 15th November for cosmic ray tests • Calorimeter: • Pre-sampler (KL): under construction in Rome • Expected at RAL 15th November for cosmic ray tests • Sandwich calorimeter: • Design complete, prototype under construction
Spectrometer and instrumentation: continued • First full tracker being manufactured: • Final step in QA chain (station acceptance rig) now in full production mode • Space frame being built • Support frame in manufacture • Electronics: • Being prepared for shipping in FNAL • Will be shipped this week or next week
Cosmic-ray integration test: • Will start 12Nov07: • Will include: • CKov, Tracker, ToF, and KL (pre-sampler)
Other Issues • Xmas shutdown • Well 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 hall • False floor should be completed in time for decay solenoid to move for cool-down tests • Other news • Water 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 12Nov07 • Craig MacWaters coordinating test • Will use R8: • 3-phase, water, etc. being planned • Unforeseen expense (likely small, but being estimated) • Components: • Tracker: • Station acceptance QA rig now running at Imperial • Station ‘5’ (first final station) has been QAed:results OK; • Decide today 15:30(?): proceed with QA or more studies required on station 5 • Space frame in manufacture • Cosmic stand signed off for manufacture (?) • TOF: • Expected to arrive 15Nov07 • KL: • Expected to arrive 15Nov07 • CKova • Already at RAL, needs to be assembled • DAQ • Already 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, China • conductor ready to order • RF cavities will be similar to existing MuCool prototype • fabrication to get under way shortly • MuCool 201 MHz cavity R&D: • Without field now have 19 MV/M
Cooling channel components: • AFC module: • Focus coil module presently out for tender • anticipate contract award in September 2007 • two coils that can run with same or opposite polarity • 20-L LH2 absorber (plus safety windows) fits inside Oxford, RAL, KEK
Current concerns • Preparation of • The PSI solenoid • MICE target • Upstream beamline • Is the misalignment critical? • Can it be solved in time? • Connection of upstream & downstream beamline components • Radiation surveys • Many areas where these matter; • Target removal • Connection of magnets in synchrotron vault • Work inside DSA – removal of North wall • Excavation of earth for H2 vents and pumps
