Run Planning Meeting Notes, Mar 29-Apr 4, 2018

<- 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

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) - abandoned, will try again later
   • 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: Sunday 10am
6. Thanks and best wishes to Tom Carstens who retires today

1. Notes from the previous 48 hours:
   • Friday morning Hovanes identified a new beam spot; Sasha took converter thickness data
   • Friday pm started CDC high threshold runs but lost beam due to Hall C's boiling study & recovery was slow
   • Friday eve weather event probably caused CDC gas pressure alarms
   • Gas shed key is absent
   • MCC whiteboard
2. Issues:
3. Reports:
4. Run Plan
   • Schematic
   • Production running through weekend, with possible 0.5h trigger work from Alex S.
