  • SS Magnet status
  • Hydrogen status
  • Issues arising from previous running
  • Operations :
    • C&M System Check report (Ajit/Ed)
    • Establishing a timetable for the runup : when should systems (including magnets) be ready for running?
      • Beam schedule
        • Run up on Jan 30 - Feb 12.
        • Start of user cycle : Feb 14
        • Start of data-taking : Feb 15
      • Reserve shifter support from Feb 10 - Feb 14
      • MOM formally starts on Feb 9 (but should be present for the runup activities but will not be on 24-hour call)
      • Possible runup plan (framework for discussion)
        • Monday 6th : Preparation meeting with Ed/Ajit/Colin/Josef/Others to go over readiness for running
        • Tuesday 7th (subject to meeting on Monday) : Bring up magnets to running configuration, take some pulser data and take magnets down
        • Saturday 11th : Expert led run without solenoids + Beam tune
        • Monday 13th : Triage actions arising from expert led run
        • Tuesday 14th : Bring up magnets in the evening and monitor overnight by reserve shift.
        • Wednesday 15th : Data-taking start at 08:00
  • Shift signup for first half of Feb is viable now (but not full)
Shift Block ID # signed up # shifters still needed
1 6 0
2 4 2 Need one overnight shift per night (5 nights) for monitoring
3 4 2 Need one overnight shift per night (5 nights) for monitoring
4 4 1

Magnet monitors do not need to be trained shifters

  • BLOCs are needed : Feb 20 - 24 and Feb 27 - Mar 1
  • AOB:

Minutes

  • CC Magnet status (J Boehm)
    All 3 CC magnets are now in flip mode; cold and full of helium. Everything is presently being run into shorts for the CC IOC testing.
    Handover from Pierrick is in progress. A few GUIs have been changed.
    Are seeing instability in SSU power supply (into shorts): last week suddenly ramped from 150 to 215 A; lost control of GUI; ramped down manually.
    Similar last night, with control cables disconnected from the AMI controller - again unstable and major changes in current on its own, implies a hardware issue.
    Now running with a different controller - seeing issues still. May possibly be associated with a purely resistive load.
  • Hydrogen status (M Tucker)
    Cooled down in R9 with Neon, made 2 to 2.5 litres of liquid, less than 1 K difference between condenser and absorber.
    Expect about 1 l every 6 hours, so over 5 days to fill with LH2 needing a 24hour rota.
  • Issues arising from previous running (DC)
    Need a comprehensive list of encountered issues, else can't assume they will be addressed before running resumes. We are now well past halfway through the shutdown.
  • Shutdown work in Jan and Feb ( official version )
    Issues/Progress on workplan items (using a stale list):
    • PT100s - done
    • ODH sensor service - done
    • POMPOMs sensor test - done
    • Neutron Monitor: ISIS can't do it; will return to MICE for us to make arrangements. Continue with temporary monitor this cycle.
    • Proton Absorbers - remedial work done
    • "New" chiller plumbing - done
    • #1878 Trench heat exchanger to counter-flow - done, possibly some small leaks
    • Diffuser iris 4: needs next SSU run: Tuesday 7th
      Compressed air: Activair coming to check the outside compressor to see why it didn't come on.
    • #1399 MICEnet lockout - tomorrow morning
    • #1888 Diffuser air - reported done
    • Airflow monitoring changes - done
    • PPS Functional Test - done
    • Earth leakage tests - done
    • New target1ctl - issues with O/S and libraries...
    • R78 - replacement flanges in progress
  • C&M System Check report (Ajit/Ed)
    CC Magnet UIs/IOCs tested last week - changes have been made on various machines, need to be aggregated.
    Target SM tested today.
    Need to test Run Control: Thursday?
    Need to review the tags listed in the CDB
    The NIKHEF Hall probes have been separated out into a different IOC.
    Most of the hardware stuff is done.
  • Run-up plan
    • Roof water/chiller needs a load test with the air-blast active - tomorrow or Thursday subject to Hall work and state of pipes
    • Monday 6th: Preparation meeting with Ed/Ajit/Colin/Josef/Others to go over readiness for running; remove shorts from link boxes, ATW and other prep.
    • Tuesday 7th: Bring up CC magnets to running configuration, take some pulser data and take magnets down; check Diffuser operation
    • Saturday 11th - Half-day of ISIS beamtime: expert led run without CC Magnets + Beambump tune (Hayley, NB Ed has to leave mid-afternoon)
    • Monday 13th: Triage actions arising from expert led run; BLOC training on everything that isn't target
    • Tuesday 14th: Bring up magnets in the evening and soak-test overnight (reserve shifters).
    • Wednesday 15th: Data-taking start at 08:00
  • Shift signup:
    With the LH2 install going ahead there will be no running during second half of 2016/05 and thus no available shift allocation - MICE that have not yet made shift quota take note.
  • AOB:
    Linde Gas Analyser webcam - where has it gone? It is being PAT tested.

Actions

  • JBoehm to get SS operating info from PHanlet (ongoing)
  • JBoehm to get/impose consensus from SC Magnets group on running of "Central CC GUI"
  • DC to collate list of issues arising from previous running
  • Status of miceraid5 disk cleanup (stands)
  • AKurup to make and circulate plan for NIKHEF probe IOC
  • SBoyd - ISIS machine-physics beam time
  • DC to ensure Health Physics have checked temporary neutron monitor (stands)
  • SBoyd - ensure MICE-wide discussion of MOM C&M panel
  • Henry to get gaps in BLOC rota plugged
