Integrated Trigger Count

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= ?? h 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).
• 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: %
  • PERP 0/90: %
  • PARA 45/135: %
  • PERP 45/135: %
  • AMO : %

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

• CDC & FDC response studies at high luminosities.
• 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)
