1 Technical Board and Safety Summary Michael S. Zisman Center for Beam Physics Accelerator & Fusion Research Division Lawrence Berkeley National Laboratory MICE Collaboration Meeting-Harbin January 17, 2009

2 Tech Board & Safety Summary: Zisman2 Safety (1) High-level MICE-ISIS Safety Committee meets regularly —a policy forum, not for detailed safety issues Two recent accidents, one causing lost time, have put us “on the radar” with the RAL safety group —this is not a good place to be MICE was asked to appoint a Safety Committee —AN, with EB concurrence, chose to use Technical Board for this purpose o augmented by a few key people –John Alexander (DL; PPS) –Willie Spensley (MERIT; CDM Principal Contractor) –Mike Courthold (RAL; cryogenics) –Matt Dickson (STFC Health & Safety) Initial task is to review PPS functionality

3 January 17, 2009Tech Board & Safety Summary: Zisman3 Safety (2) Information on safety-related aspects of all MICE equipment must be conveyed to Andy Nichols for Safety Committee discussion —need early indication of risks, hazards, and planned operating procedures to permit risk assessments o most proposals can be made acceptable with proper planning CDM regime will continue throughout most of MICE duration —Phase 2 equipment may need specialist review o TB will coordinate this

4 January 17, 2009Tech Board & Safety Summary: Zisman4 Technical Board Met on Wednesday afternoon —discussion topics o Spectrometer Solenoid status o Summary of Coupling Coil review o EMR electronics purchase o Integration task o Review status o Phase 2 schedule and cost-to-complete

5 January 17, 2009Tech Board & Safety Summary: Zisman5 Spectrometer Solenoid Plans are acceptable —expect first device to ship at end of February o second one 2-3 months later Magnet 2 cold mass assembly Magnet 1 being disassembled

6 January 17, 2009Tech Board & Safety Summary: Zisman6 Coupling Coil Review team included outside reviewers —Alan Bross (FNAL, Chair) —Mike Green (LBNL) —Vladimir Kashikhin (Fermilab) —Wing Lau (U. Oxford) —Derun Li (LBNL) —Steve Virostek (LBNL) —Zian Zhu (IHEP) —Mike Zisman (LBNL) Review went well —technical issues are in excellent shape —manpower situation is still not comfortable —some “cash flow” problems at HIT that were slowing down ordering o schedule shown deemed likely optimistic (11/09) –and has already slipped a bit

7 January 17, 2009Tech Board & Safety Summary: Zisman7 EMR Electronics U. Geneva asked permission to order some electronics in advance of commitment from INFN to build the device —conclusion was to approve purchase o EMR design is deemed as correct one, and we will proceed with it one way or another…even if INFN cannot fund it

8 January 17, 2009Tech Board & Safety Summary: Zisman8 Integration Task Scheme developed (Lau) for cooling channel seems to be effective —at present, there is no corresponding integration effort for the detectors —recommend that Lau continue identifying and monitoring integration issues for detector area o in effect, manage integration at Level 1, not Level 2

9 January 17, 2009Tech Board & Safety Summary: Zisman9 Review Status Two reviews identified as being ready to organize —software and DAQ Both have been slow to happen —will ask Rose Hayes to contact reviewers to try to set up dates for these reviews ASAP Tech Board needs to be more proactive in reviewing key aspects of the project —what level of review should depend on the system being considered and its technical and cost risks to MICE o one size does not fit all!

10 January 17, 2009Tech Board & Safety Summary: Zisman10 Phase 2 Update Agreed with need to update cost-to-complete and schedule —need to create mechanism for doing this and updating it periodically o process was initiated more than a year ago, but went idle due to other pressing issues —may also need to prioritize tasks in view of limited time, funding and intellectual resources

11 January 17, 2009Tech Board & Safety Summary: Zisman11 Final Remarks Focus on safety aspects is necessary and important —using Tech Board for this process will be an efficient way to proceed It is important that the Tech Board be involved in discussing and approving technical decisions of MICE —we must not let urgency serve as an excuse to bypass this mechanism o for example, target issues and decay solenoid repair plans need to be discussed and approved in this forum
