  1. MICE All Hands MeetingPM report • Brief overview • Organisation and project management • A personal view on the top-level schedule • Update on liquid hydrogen and RF Infrastructure • Coupling Coil update • Substation upgrade • The next few years Andy Nichols, STFC

  2. Overview • Muon beamline reliable, decay solenoid now working • Target development is going very well, working ISIS target continues to give reliable service, offline programme making good progress, stator re-engineering made good start • FC #1 manufacture is progressing, but significant delay due to coil-winding problems • RF cavity production well on schedule, both sets of 4+1 made – major success • Spectrometer solenoids – in depth review complete, repair plan submitted to MAP, feedback expected end Feb • 2MVA substation upgrade – about to place contract, more later • Diffuser – design change to IRIS type, much simpler to make • PPS - is commissioned, DSA component ready for when ISIS resumes • First EMR planes delivered by July, MICE running programme planned for that date

  3. Organisation and Project Management • Some changes to the project management are in process: • UK project re-modelled: • UK Project Manager - Vacancy (AN, helped by KL till filled) • System Engineer RAL – Tim Hayler • System engineer DL – Alan Grant • Project Associate – Andy Lintern • MICE Project: • Project Manager – Andy Nichols • Integration Engineer – Jason Tarrant • MICE Magnet co-ordination team • Engineering – Roy Preece • Magnetic – Mike Courthold • MICE Admin Office • Mary-Elizabeth Shewry • Rose Hayes • Major shortfall in design effort partly addressed by welcome help from DL staff Will be proposing this plan to UKNF/MICE OsC next Monday

  4. A personal view on the top-level MICE schedule...... • Still dominated by only a few big dates: • MICE collectively decided that there is no scientific reason not to move straight to Step IV • Minimally, we need: • Hall infrastructure general and MICE Phase One – done • PPS system – Feb 2011 • Liquid hydrogen delivery system – Q4, 2011 • AFC #1 – LH2absorber ready, FC module delivery mid 2011 • Diffuser – Q2, 2011 • Solid absorbers (various) – MICE has to define specifications, not difficult to make absorbers, hope to do at CM29 • Spectrometer solenoids - #1 January 2012, #2, April 2012, MAP hopefully converges at end Feb this year • Substation upgrade – Q3 2011 • We then have a few months of necessarily series operation to integrate Step IV – session reserved at CM29 to work it out • If we don’t like the date that falls out, it’s up to us to find a way to accelerate

  5. Update on liquid hydrogen and RF infrastructure • Given late delivery of spectrometer solenoid, UK effort was redirected for FY10/11 to LH2 & RF, both high technical risks • Much liquid hydrogen hardware delivered • SIL rating exercise completed • A serious start made on RF infrastructure layout • Priority is identifying hardware to buy • Refurbishment of second LBNL amplifier well underway

  6. R&D cryostat, valve panel, enclosure and transfer line • Tested and delivered in November • Installation making good progress • Vent system design is designed • Electrical installation for controls and safety going well • Parallel exercise with safety documentation – plenty of niggles

  7. Liquid Hydrogen system • Milestone commentary: • Electrical work complete – end February 2011 • Mechanical installation complete - April 2011 • Start ventilation ductwork – end January, 2011 • Start Helium testing (a pre-requisite to hydrogen operation) - April 2011 • Complete Helium tests – June, 2011 • Pre hydrogen operation safety case prepared – July, 2011 • Then start hydrogen tests – Q3, 2011

  8. RF Infrastructure Have only very recently been able to start the real CAD work, due to shortage of staff. but, good start made, beginning to understand waveguides, water loads, services, etc Good news is that on first look things seem to fit with floor

  9. RFCC Module Update - Introduction • The Radio Frequency Coupling Coil (RFCC) modules are a significant part of MICE Steps V & VI • The are managed by LBNL for MICE, with a large input from four Chinese organisations • Until CM28 in October, they were more or less a closed book (to me anyway) • But I got invited by Derun Li to the following: • Cryostat final design review in Shanghai • Tour of Harbin Institute of Technology • Tour of Qi Huan in Beijing • Quite useful – at least I’ve been allowed to form my own idea of the ‘problems’ for the first time

  10. Magnet/cold mass Cryostat/vac-vessel RF cavities RF vac-vessel

  11. 冷质量机械中心转移 冷质量靶标点 共8点 真空室上靶标座 16点 焊接在真空室外的靶标座

  12. Organisation and responsibilities • MICE RFCC WP Manager – Derun Li, LBNL • MICE RF Cavity Manager - Allan DeMello, LBNL • Chinese funding agency – Guo Bin, Harbin Institute of Technology (HIT) • Testing of cold masses, welding of cooling tubes and cover plates – Liyi Li, Institute of Cryogenic and superconducting Technology (ICST) • All manufacturing and fabrication – Qi Huan, a private company, nominated by HIT without meaningful MICE involvement • Project management in China, including engineering drawings – Wang Li, Shanghai Institute of applied Physics (SINAP) • Day to day engineering management at ICST – Feng Yu • Ditto at SINAP – Lixin Yin

  13. Sequence of events (I think!) • Design work for the CC is overseen by Wang Li and Lixin Yin • The coils are wound by Qi Huan and then shipped to ICST for: • Welding on of cooling jacket/pipes (the magnet is indirectly cooled by conduction) • Testing of the complete cold mass in a simple cryostat using a Linde plant (which has not been used for some time) that is similar to ours • Qi Huan manufacture the vac-vessel • Cold mass is shipped back to Qi Huan, who do the final assembly • Magnet is presumably cooled and tested with CCRs at Qi Huan • Then it’s shipped to LBNL for RF cavities and vac vessel to be fitted

  14. Status • Technical baseline has been approved by MICE • A detailed project plan (but mostly in Chinese) exists • A ¼ scale test coil (final diameter, but with fewer coils has been made • Some detail manufacturing drawings of the cryostat are complete • The first real coil (called #1) is wound and is just having the banding applied - it will go to either MICE or MuCool • Some work has been done to get the cooling test set up done, transfer lines, control electronics, etc • Test cryostat is made

  15. Risks & worries • In no particular order: • Fabrication of the cryostats and post machining is a huge job – were unable to see Qi Huan’s facilities as they are moving • Not clear that indirect cooling will work – apparently this was raised by a Review Committee – mitigation is >100% cooling margin, but track record is appalling! • Despite assurances about reorganisation, skilled manpower at ICST is lacking • No work done yet on tooling or fixtures for welding cooling jackets • The cryostat is now very large, static weight must have increased by 50% and will definitely interfere with South mezzanine • QA and general discipline is very weak, eg – important features like lead support and heat sinking are being designed on the hoof • Simply getting about and communicating, even with native speaker in tow, is a real challenge

  16. What we might do about them.... • Offer material help, eg: • Take responsibility for discrete items, cryostat, tooling, weld fixtures and so on • Offer technical help, get Linde plant running • Assist with controls engineering – in fact this could be part of our ‘common approach’ to this topic • Help Derun with schedule construction – this is a priority • All the above will need non-Chinese resources • And we need to make sure our help is welcome – not clear at the moment • KL and AN, with support from Alan Bross, both believe that there is an opportunity to formally widen the collaboration and share the risk with a properly thought out proposal to STFC

  17. Schedule and rest of MICE • From discussions mainly, it looks like this: • Cooldown test rig to 4.2K – end Jan 2011 • Complete cooling and testing of test coil – May 2011 • Install coil #1 in cryostat & test – June/July 2011 • Ship coil #1 to ICST – August 2011 • This is the limit of understandable information..... • My own interpretation takes over: • Weld cooling jacket to cold mass –December 2011 • Ship cold mass back to Qi Huan – Q1 2012 • Assembly of magnet #1 in cryostat – Q3 2012 • Ship to LBNL – Q4 2012 • Assemble RF cavities, vac vessels & test – early 2013, who knows!

  18. Schedule and MICE • At some point MICE has to decide if magnet #1 goes to MICE or MuCool • If it goes to MICE, it’s conceivable that it comes to RAL around mid-late 2013 (my view only of course) • That would point to doing Step V in early 2014 • But as with the spectrometer solenoid, AN will not endorse or believe any delivery dates until the detail schedule and risks have been understood • Hot off the press: • M.Zisman is proposing to MAP (Muon Accelerator Programme) five options for proceeding • Ranging from staying as we are(!) to a complete start again with new vendors and organisation • Guidance from MAP awaited.......

  19. Substation upgrade • Reminder: MICE needs 2MVA electrical supply to run at Step IV • Good news: permission given by STFC last year to go ahead • Option with all new equipment has been approved • Specification written and design work complete • Trouble-free tender exercise • Two realistic, almost in budget, offers from TES and JV Morris, from three approaches • Hope to place contract next week, meeting next Tuesday to finalise vendor • Detailed schedule at discretion of vendor • But installation will be late Spring – need to watch for EMR run in July • Project led by Building Project Group, but with technical input by DL Electrical and Controls Group

  20. The Next Few Years • MICE Project Board has asked us to explicitly define an end date for the project • Not as easy as it sounds – see previous slides! • Because of the good work done on the spectrometer solenoid, we can certainly plan up to Step IV with some confidence • Will start to re-define the famous schedule cartoon at CM29 in February with Step IV as a new starting point • Individual schedule information will be assimilated in the technical Board and schedule agreed by EB at end of meeting
