Hall D counting room white board
Contents
Friday March 10
Past 24 hours
- DAQ issue with live time drop to 0%, Surgey reset gluon01 crate to resolve the issue.
- Production continues
- Four hall operation, beam was trippy during the day but got better over the swing shift
- ABU=4.22 hr(day shift)
Shift Reports
- Day Shift Summary
- Swing Shift Summary
- Owl Shift Summary
- [Early Riser Shift Summary]
Reports
- Main Trigger Scalar frozen restarted (Alexandre D.)
- FCAL Base (22,55) lock up and reset Day shift
- FCAL Base Lock up alarms:swing shiftFCAL Base lock up (42,7) and (45,13)
Issues
- TPOL alarms
- DAQ live time 0%, restart did not solve, Surgey had to reset gluon01 crate: solved(shift crew will be watchful if it reappears)
- Active collimator: alarms to EPICS (Lubomir and Hovanes to communicate for TPOL card(1/2))
Plans
- Opportunistic Access by Zisis/Karthik for mini BCAL prototype
- TAC run (next week?): 1) Energy measurement at HallC 2) Bleedthrough measurement at HallD and if HallC run low current or down 2 hours at least, Sasha will do TAC run, Hall C run co-ordinator will look and communicate if that is the case.
Regular Production Cycle
- Production (300 nA, 2h runs) with cycle:
- 2 runs PARA (0/90)
- 2 runs PERP (0/90)
- 2 runs PARA (45/135)
- 2 runs PERP (45/135)
- 1 run AMO (use it to rejuvenate AMO reference in CBREM EPICS GUI)
Thursday March 9
Past 24 hours
- Work on Injector(early day shift): completed, beam restored.
- HI test(900nA) Pb and Mo foils, HI study completed at the end of day shift and nominal production conditions restored including AC gain 10^-8
- Production resumed at swing shift with AMO radiator configuration
- Rate Scan study by Sasha: Swing shift, raw and production mode at different currents:300nA, 350nA and 400nA
- Production resumed with 0/90 PARA after Sasha's rate scan completion
- Beam off due to 1L09 tripping high voltage(~1.5hr)
- Beam (trippy) early owl shift, then better beam, then beam current was fluctuating and was under 300 nA
- ABU=11.28 hr(till 8 am 3/9), ~2 bn production triggers till 5 am 3/9, smooth running over the night
Shift Reports
Reports
- High intensity test with Pb and Mo foils(Justin)
- [1] [2] Pb and Molybdenum foil inserted](Lubomir)
- Doubled the thickness of the Molybdenum (Lubomir)
- [3] [4] CDC currents with W and W+Pb foils (Naomi)
- CDC currents with W and Mo foils (Naomi)
- CDC AI on 16:25 3/8 swing (Naomi)
- Beam halo alarms
- Missing data on channel 23 TPOL(Roman)
- FCAL Base Lockup
- Beam Current over the night (Jesse)
- [5][6]TPOL occupancies not flat before reset of rootspy](Yannik)
Issues
- TPOL alarms
- DAQ issue this morning: live time dropped to 0%, restarting solved the issue
Plans
- TAC run whenever opportunity comes( HallC run at small current or down)
Regular Production Cycle
- Production (300 nA, 2h runs) with cycle:
- 2 runs PARA (0/90)
- 2 runs PERP (0/90)
- 2 runs PARA (45/135)
- 2 runs PERP (45/135)
- 1 run AMO (use it to rejuvenate AMO reference in CBREM EPICS GUI)
