Spreadsheet with list of runs

Thursday January 26

Past 24 hours

• Production on diamond. ABU= 10 h for the day.

Shift Reports

• Day shift summary
• Swing shift summary
• Owl shift summary
• Early Riser shift summary

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

• Day shift summary
• Swing shift summary
• Owl shift summary
• Early Riser shift summary

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.

The left Ar gas supply bank is empty

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

• 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)
