Zoom Connect Meeting ID: 160 199 0060 / Passcode 8394
Hall D counting room white board
Past 72 hours
Saturday March 11
- Production
- Opportunistic Access(Friday): Karthik, Zisis, Stejphan: (EIC) mini BCAL prototype test
- Hovanes:TPOL crate powercycled
Shift Reports
- Day shift March 10[ Day shift March 11][ Day shift March 12]
- [ Swing Shift March 10][March 11][March12]
- [ Owl Shift March 11] [March 12][March 13]
- [ Early Riser Shift March 11] [March 12][ March 13]
Reports
Issues
TPOL alarms after Powercycle of crate
Plans
- bleedthrough measurement sunday? or TAC run when the opportunity comes.
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)
Friday March 10
Past 24 hours
- Production continued
- Four hall operation until ~11 pm, then HallC down until the morning. A,B and D operational overnight.
- Beam was trippy during the day but got better over the swing shift through owl shift.
- ABU=10.37 hr(midnight), ~4bn triggers
Shift Reports
Reports
- Main Trigger Scalar frozen restarted (Alexandre D.)
- FCAL Base (22,55) lock up and reset Alan G.
- FCAL Base Lock up alarms:SashaFCAL Base lock up (42,7) and (45,13)(25,27), (-5,-3): Rebecca B.
- Off node in addition to base lock: required to reset [Jesse H.]
- Strip charts for DAQ status, current, PS/PSC rates etc..
Issues
- TPOL alarms continued
- DAQ live time 0%, restart did not solve, Surgey had to reset gluon01 crate: solved
- DAQ issue early riser this morning: ROCFCAL error,DAQ reset (solved)
- Active collimator bias voltage:[1] alarms to EPICS (Lubomir and Hovanes to communicate for TPOL card, one is in use. We should have one more somewhere)
Plans
- Opportunistic Access by Zisis/Karthik for mini BCAL prototype
- TAC run (next week? or 3/10: HallC down for the night and probably for entire morning)
- Energy measurement at HallC
- Bleedthrough measurement at HallD
- if HallC run low current or down for 2 hours at least, Sasha will do some work on TAC run.
- 3/10 HallC will have some down time at least some part of morning confirmed from HallC RC(Joerg), can we do some tests during HallC downtime?
- Sasha Positive for the morning(3/10) based on HallC condition till that time.
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)
- [2] [3] Pb and Molybdenum foil inserted](Lubomir)
- Doubled the thickness of the Molybdenum (Lubomir)
- [4] [5] 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)
- [6][7]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)
