Hall D counting room white board
Contents
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= xx h for the day.
Shift Reports
Reports
- Barometric pressure alarm (Hovanes).
- MCC is scheduling maintenance for Feb 1st
- Trigger fine tuning Sunday (A. Somov)
Issues
Start Counter HV match test (Beni) Given the results of this test, the next step is to figure out if there is a physical rotation on the counter. DIRC SiPM Update (Justin) The inverter box was installed. However the TDC scaler still shows zero occupancy in channel 30 of slot 8.
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.
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)
