Hall D counting room white board
Thursday January 26
Past 24 hours
- Production on diamond. ABU= 10 h for the day.
Shift Reports
Reports
- Alternative to barometric pressure measurement (Naomi). Whiteboard instructions have been updated.
- Online calibrations started (Sean)
- MCC is scheduling maintenance for Feb 1st
Issues
- Follow up on HallD dp variation
- Start counter 96 degree rotation in cabling or software space (Simon).
- Tentative plan of action: To turn off the low voltage to the SiPM bias for a few specific start counter paddles and take a 1-hour run where we can identify the physical location of these paddles using the tracking detectors.
- DIRC LED TDC missing (David Lawrence, Justin) DIRC SiPM reference signal (Justin)
- Tentative plan of action: Chris Stanislav will have a spare this afternoon and Justin will install during an opportunistic access
- Fixing FCAL Bases Lockup (Jon)
- Beam Downtime Re-steering Arcs This might need a while to be fixed. They are hoping this fixes some issues they have been seeing in the past few days.
- TPOL GAP (Beni): this is a translation table issue (Justin)
Pending:
- BCM calibration. Accelerator instrumentation group informed us that last BLA calibration was done in 2021 (beside that done last Thursday, 01/19/2023? To be confirmed) and recommend Ops to do one at each start of the run period.Talked to the PD, he will keep in contact with us on how to proceed.
- A request for the kitchen lights to be fixed should be submitted next time there is beam downtime.
Plans
- 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 GUI)
- Trigger fine tuning Thursday? (A. Somov)
Friday January 27
Past 24 hours
- Production on diamond. ABU= 1.3 h for the day.
Shift Reports
Reports
- MCC is scheduling maintenance for Feb 1st
- Barometric pressure alarm (Hovanes).
- DIRC SiPM Update (Justin) The inverter box was installed and it is working
- Harp Scan Results Could we add procedures on how to judge the results for the extrapolation?
- The left Ar gas supply bank is empty The new supply will be swapped out today
- Trigger fine tuning Sunday (A. Somov)
- GlueX Statistics
- PARA 0/90: 11%
- PERP 0/90: 14.1%
- PARA 45/135: 15.2%
- PERP 45/135: 15.5%
- AMO : 44.2%
Issues
- Start Counter HV match test (Beni) There is a physical rotation on the counter.
Pending:
- BCM calibration. Accelerator instrumentation group informed us that last BLA calibration was done in 2021 (beside that done last Thursday, 01/19/2023? To be confirmed) and recommend Ops to do one at each start of the run period. PD will keep in contact with us on how to proceed.
Plans
- Harp scan once beam returns. Then continue 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 GUI)
Monday January 30
Past 72 hours
- Production on diamond. ABU= xx h for the day.
Shift Reports Friday
Shift Reports Saturday
Shift Reports Sunday
Reports
- MCC is scheduling maintenance for Feb 1st
- Monday the beam will be off for ~3 hrs. They will power up RF for 5th pass (~2hrs) and then 4th pass (~1hr). These tasks are related to the Moller polarimetry measurement of Hall A
- Start counter resolutions look reasonable again (Sean)
- tagger energy calibration updated in ccdb (Richard)
- Follow-up: TAGM mapping after installation (Richard)
- FCAL voltage scan
- GlueX Statistics
- PARA 0/90: x%
- PERP 0/90: x%
- PARA 45/135: x%
- PERP 45/135: x%
- AMO : x%
Issues
- TPOL channel 23 missing (Justin) TPOL occupancy hole (Hovanes)TPOL Presentation (Michael Dugger) We can check it on Wednesday during maintenance
- TAGH HV crate problem again (Hovanes)
- FCAL has new hot channels (Hovanes)
- Missing TAGH FADC channels (Hovanes) (Probably on purpose)
- We might need to add a few extra runs for -45 trigs to catch up to the others
Pending:
- BCM calibration. Accelerator instrumentation group informed us that last BLA calibration was done in 2021 (beside that done last Thursday, 01/19/2023? To be confirmed) and recommend Ops to do one at each start of the run period. PD will keep in contact with us on how to proceed.
Plans
- Opportunistic access to reset tagger (To be confirmed after morning meetings)
- Harp scan after beam is restored
- Sasha will perform trigger studies in the 10pm - 4am shift.
- 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 GUI)
