<- Back to Run Coordination Meetings:Fall2017 Spring2018 Run
Thursday, March 28 at 08:45
- 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
- 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)
- Reports:
- 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
- AOB
Friday, March 29 at 08:45
- 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
- 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
- Reports:
- 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.
- Next meeting: MONDAY 0845
- Thanks and best wishes to Tom Carstens who retires today
Monday, April 2 at 08:45
- 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
- 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.
- Gas shed key is absent
- Easter egg hunt (find the popup) - Hovanes will look at this after the run period ends
- Reports:
- 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
- AOB
