Hall D counting room white board
Contents
Friday February 17
Past 24 hours
- Mark D. replaced the bad BCAL HV board with a new one at 9:40am.
- No beam from 13:00 to 17:30 (0L40 cryo issue). Several people worked in the hall during this downtime.
- Production runs resumed after beam came back.
Shift Reports
Reports
- Please don't prestart very early (Naomi)
- TAGM scaler issue resolved (Hovanes)
- BCAL HV board changed [1] [2] (Mark)
- hydra
- Higher occupancy in FDC -> No efficiency decrease is seen. (Lubomir)
- Statistics balance
- PARA 0/90: 20.9%
- PERP 0/90: 19.9%
- PARA 45/135: 20.8%
- PERP 45/135: 20.4%
- AMO : 18.1%
Issues
- A bad voltage board in the BCAL. Needs to be changed. (Mark)
- HallD Run #120726: LED ADC reference SiPM time anomaly
- Discrepancy in FDC wire occupancies, run 120737
Pending:
- Start Counter (Beni) - We do not understand why there is a mismatch in the software between start counter and tracking.
- BCM calibration. Alexandre recommends that we request a recalibration of AD00C BCM. (~30 mins?)
Plans
- Install CCAL whenever there is an extended accelerator downtime
- Restricted Access is needed to be able to use the ramp <-done
- Cabling
- Survey is needed
- 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 February 16
Past 24 hours
- Production runs with a stable beam.
- 2 BCAL HVs have been off since midnight due to a bad voltage board.
Shift Reports
Reports
- Rebooting NMR meter and its IOC (Hovanes)
- target LCW temperature alarm (Alexandre)
- Noise on some TPOL channels (Data should be good enough). (Michael Dugger, Beni)
- Statistics balance
- PARA 0/90: 20.9%
- PERP 0/90: 19.9%
- PARA 45/135: 20.8%
- PERP 45/135: 20.4%
- AMO : 18.1%
Issues
- A bad voltage board in the BCAL. Needs to be changed. (Mark)
- HallD Run #120726: LED ADC reference SiPM time anomaly
Pending:
- TAGM discriminator TRG scaler gone wild
- Start Counter (Beni) - We do not understand why there is a mismatch in the software between start counter and tracking.
- BCM calibration. Alexandre recommends that we request a recalibration of AD00C BCM.
Plans
- A bad BCAL HV board should be changed. Chris Stanislav is out today, and Mark D. is trying to find someone to change the BCAL board.
- Install CCAL whenever there is an extended accelerator downtime
- Restricted Access is needed to be able to use the ramp <-done
- Cabling
- Survey is needed
- 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)
