      • 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:

• Last meeting : Tuesday Jan 24 2017
• Next meeting : Tuesday Feb 6 2017

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:
  Note that with the LH2 install going ahead there will be no running during second half of 2016/05 and thus no available shift allocation

• AOB:
  Linde Gas Analyser webcam - where has it gone? It is being PAT tested.

Actions¶
