Thursday January 26

Past 24 hours

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

Shift Reports

Reports

Issues

Pending:

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

Issues


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)

Past 72 hours

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

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) -> at least 1 extra run to catch up (~.6B triggers down) [corrected]
    • 2 runs perp(45/135)
    • 1 run amo (use it to rejuvenate amo reference in CBREM GUI)

Wednesday February 1

Past 24 hours

  • Production on diamond. ABU= 13.5 h for the day.

Shift Reports

Reports

  • Maintenance day Requested Controlled Access for Tagger Hall and Restricted Access for the main Hall. Tour starts at 13:00
  • During the Day and Swing shifts the beam was unstable going 300 nA +/- 20 nA
  • Preparations for task 9 of Run Plan. Email with a detail explanation of the plan was sent to the PD, we are waiting to hear back from them.
  • BCM calibration. Accelerator instrumentation group informed us that last BLA calibration was done in 2021 (beside that done Thursday, 01/19/2023? To be confirmed) and recommend Ops to do one at each start of the run period. PDF of BLA Calibration Procedure From Shawn Frierson reply "[Given what the procedures suggest,]we would need to go back to how it was done back in ’21 (according to Alexandre) to see what was done differently. Another option could be to perform it when the request for “high” current (>450nA) is fulfilled." To first order, The BLA calibration could be done during the high intensity scans (since we may go up to 1μA).
  • Trigger rates in 2020 and 2023 (A. Somov)
  • Since Beni saw yesterday the TPOL channel 23, we do not need to check it out today
