<- Back to Run Coordination Meetings:Fall2018 Run
- Trigger Spreadsheet Started Filling out on 9/28/18
- Run Plan Google Calendar
- Accel. Plan Google Calendar
Friday, Nov 1 at 08:45
- Last 24h
- active collimator scan done. The intention was to make sure that the beam was centered on the collimator and then decide whether to ask for beam convergence adjustment but the results were confusing and we decided to continue running without changes for now.
- Mark filled both alcohol bubblers
- Sasha looked at BCAL LED trigger timing - hopefully this is fixed
- Production - beam trips quite frequent
- Cleared up some mysteries from yesterday - a network issue was the cause of the beamline counters switching off. It should have triggered an alarm but didn't. And the TagM mess was indeed when the DAQ config was set to cosmics.
- Issues
- Target water temp alarm every 1.5h through the night
- One FDC channel tripped, was reset
- Reports
- Plans
- Production
- Tentative plan for V-wire TAC run on Wed next week at 2 PS settings, nominal & lower Eg. Then follow with low Eg test runs. Maybe a 3rd TAC run after the low E data-taking.
- Q on whether to go ahead w second set of 7GeV test runs - need collaboration agreement
- Remember to make a plan for the clocks changing on Sunday
- Schedule for week 7
- Acc whiteboard
- Counting house whiteboard
- AOB
Thursday, Nov 1 at 08:45
- Last 24h
- 7GeV coherent peak test run completed
- Raw mode run completed
- BCAL LED run for Elton when beam went off
- Rest of time - mostly production
- Approx 9pm the tagger chain dipole (not the Hall D tagger) power supply failed. Fixed after midnight. Some problems restarting as many beamline counters had tripped apparently without alarms
- Issues
- Beam focus5C11 harp5C11BHall DJay
- Fixed: beam fiducial times now in ccdb again
- Shift checklist Qs, from Mark
- Elton re BCAL LEDs
- Is the cosmic production trigger config out of date?
- Reports
- Plans
- AOB
- Notes from today's meeting: Hovanes to scan AC early pm.
- Shifters to call Sasha if beam goes off for >= 1h during weekend daytime, to check BCAL LED trigger diffs between up & down and long & short modes
- Sasha said shift crew should not use the cosmic trigger at all. Use production trigger even if only to collect cosmics during a long down-time.
- Tentative plan for V-wire TAC run on Wed next week at 2 PS settings, nominal & lower Eg. Then follow with low Eg test runs. Maybe a 3rd TAC run after the low E data-taking.
- Q on whether to go ahead w second set of 7GeV test runs - need collaboration agreement
- Remember to make a plan for the clocks changing on Sunday
