h2. 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":https://micewww.pp.rl.ac.uk/attachments/download/8158 )

  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.

h3. Actions
