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

- 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
