Thursday February 3

Past 24 hours

• Recovery from maintenance day. A couple of production runs. PSPEC troubleshooting. Test runs.
• ABU ~11.2h based on Beni's text messages.

Shift Reports

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

Reports

• Power supply trip (Tim, Scot).
• PS magnet at 800A (Eugene).
• ALERT to shift leader: two TAGM columns still at operating Vbias (Richard).
• Current scan to 950nA (Lubomir)
• PSPEC current scan (Sasha)

• GlueX Statistics
  • PARA 0/90: 16%
  • PERP 0/90: 19%
  • PARA 45/135: 20%
  • PERP 45/135: 19%
  • AMO : 25%

Issues

• Pair Spec Magnet Power Supply Flush in morning (Tim) We need to get PSPEC working at 1200Amps.
• Issues with the TAGH HV module (Sasha) Need to check this board again.
• Start Counter (Beni) We want to confirm that the cables are in the right location.

Pending:

• 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. PD will keep in contact with us on how to proceed.

Plans

• Citra flush PSPEC power supply. Go to beam permit today.
• Run production over weekend.
• High current test with RADCON on Monday
• RF recovery on Tuesday. Try to raise Hall A & C currents on Wednesday and possibly Thursday.
• 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)

Thursday February 2

Past 24 hours

• Maintenance day, tour of Hall D by EIC review people. Beam is back at midnight.
• Harp scans look OK [1]
• Production on diamond. ABU= 2.9h for the day.

Shift Reports

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

Reports

• HVB current during HV scans (Naomi).
• CDC HVB current vs beam current using this morning's scan (Naomi).
• Current limits and rough estimates of safe HV (Naomi).
• Translation table updated for TAGM (Justin) .
• Swapped HV module for TAGH ch 145 to 168 (Boris).
• Attenuation in different materials (Lubomir).
• Transmission has dropped over the night (Alexandre).
• Trigger rates in 2020 and 2023 (Sasha).
• High Intensity Foil Absorbers (Scot).
• Remote reset for CAEN chassis (Tim and Bobby).

• GlueX Statistics
  • PARA 0/90: 16%
  • PERP 0/90: 19%
  • PARA 45/135: 20%
  • PERP 45/135: 18%
  • AMO : 25%

Issues

• Start Counter (Beni) We want to confirm that the cables are in the right location.
• Reconstructed Photon Beam Energy Spectrum Deep between 10-11 GeV (Churamani) May be a an issue with timing offset calibrations.

Pending:

• 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. PD will keep in contact with us on how to proceed.

Plans

• Wait for stable beam delivery for 4 halls. No timelime can be given.
• CDC & FDC response studies at high luminosities. May not happen today, depends on 1uA beam delivery to Hall D.
• 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)
