Integrated Trigger Count

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)

  • 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= 44.5 h for the weekend. (15.7 h Friday , 17.1 h Saturday, 11.7 Sunday)

Shift Reports Friday

Shift Reports Sunday

• Day shift summary
• Swing shift summary

• Early Riser shift summary

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)

• TAGH alarming channels: bad board ? (Hovanes) We have a spare.
• 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:

• Sasha will perform trigger studies in the 10pm - 4am shift.
• Production (300 nA, 2h runs) with cycle:
  • 2 runs para(0/90)
