<- Back to Run Coordination Meetings:Fall2017 Spring2018 Run

Thursday, March 28 at 08:45

  1. Notes from the previous 24 hours:
    • RF separator tested out ok, aimed to restore beam for swing shift but delayed due to CHL issues
    • Beam arrived just before midnight, convergence not good, owl shift spent tuning
    • 0800 MCC meeting notes - Todd retuning; planning machine work 4h Mon, 8h Tues MCC whiteboard
  2. Issues:
    • Shift-takers should at least log any acknowledged alarms so that they are not forgotten
    • Is there a how-to page for the BTA sheet? (load from epics, edit etc & guidelines on ABU/BANU)
  3. Reports:
  4. Run Plan
    • Re-establish Photon beam
    • 1h production to check beam quality & detectors
    • Diamond spot adjustment (Hovanes, needs to start before noon or try again tomorrow)
    • CDC Background Studies (Lubomir et al.)
    • Converter thickness study (Alex S.)
    • SSP Study (Alex S., postpone to early next week)
    • Production running

Friday, March 29 at 08:45

  1. Notes from the previous 24 hours:
      • Todd retuned Hall D beamline Thursday morning, considerable improvement
      • Hovanes set diamond positions but didn't have time for spot adjustment, #1 for today
      • CDC background studies completed ?
      • Beam became less reliable throughout swing shift, improved after midnight
    • 0800 MCC meeting notes - beam studies 0830-1230 Monday
    • MCC whiteboard
  2. Issues:
    • Some rootspy hiccups, hopefully fixed
    • Beam steering locks on 5C11B were off, there should be locks on 5C11B and the active collimator
    • Tagger quadrupole current had loaded incorrect default value during tuning! MCC will correct the default and add alarms.
    • BTA guidelines
  3. Reports:
  4. Run Plan
    • Schematic
    • Diamond spot adjustment (Hovanes, 2h) - done
    • Converter thickness study (Alex S., 2h) - done, needs to check data quality
    • CDC high thresholds (Beni, 2h) - done
    • Production running through weekend, with possible 0.5h trigger work from Alex S.
    • Over the weekend Richard will do prep work for the TAC run on Wed.
  5. Next meeting: MONDAY 0845
  6. Thanks and best wishes to Tom Carstens who retires today

Monday, April 2 at 08:45

  1. Notes from the previous 72 hours:
    • Friday morning Hovanes found a new spot on the diamond; Sasha took converter thickness data
    • Friday pm started CDC high threshold runs but lost beam due to Hall C's boiling study
    • Friday eve Accelerator recovery from boiling study was slow. CDC threshold tests postponed. Beam position inconsistent, MCC having trouble with the locks
    • Saturday early morning (owl) beam position became more stable
    • Saturday morning RF trip, no beam all morning. Mentioned trouble w beam position/locks not working to PD during morning check-in.
    • Saturday pm CDC threshold runs done; down for 3h w LCW fault; resumed production ~ 8pm
    • Saturday late swing and owl beam position good, steady overnight production
    • Sunday morning good production running.
    • Sunday swing plagued by RF cavity problems
    • MCC meeting notes
    • MCC whiteboard
  2. Issues:
    • Ops logbook entry on locks
    • Underfocused - ask Todd for retune on Monday pm?
    • Is the TagM low end ok?
    • Occasional rootspy seg faults. Digihits occupancy for PSC looks strange in monitoring plots. Sasha says maybe rootspy issue?
    • Easter egg hunt (find the popup) - Hovanes will look at this after the run period ends
    • Gas shed key is absent
  3. Reports:
  4. Run Plan
    • Schematic
    • Through weekend: production running. (Possible trigger work from Alex S.)
    • CDC high threshold runs - done
    • Beam studies on Monday 0830+ could be longer than 4h. Duration of Tuesday's work is TBD. Hall C will need to finish boiling studies but not quite yet.
    • Access requests for Monday: Lubomir. Hovanes (remove tungsten, add Pb converter to beam profiler as prep for TAC run). Elton/Sasha (for BCAL fadc)?.
    • Will need Radcon to survey collimator cave
