    • The analysis coordinator (Alexander Austregesilo) oversees the off-line diagnostic of the different systems and analysis of the data.
    • Shifts: 2 person shifts: 1 local leader and 1 (optionally remote) worker scheduled through the GlueX shift scheduler.
  • Coordination Activities:
    • The RC will attend the MCC meetings at 7:45am and 8:00am and the weekly MCC meeting (Wednesday, 1:30pm). The PDL will attend the weekly MCC meeting.
    • Run meetings: broadcasted on Bluejeans. 8:45am in the counting house conference room. The Run Coordinator will be responsible for organizing and chairing the meeting.
      • Start of run: Daily meetings
      • Production: Alternate nominal length meetings (Monday/Thursday) with short meetings (Tuesday, Wednesday, Friday)

Readiness for Summer 2021 Run

  • Solenoid (Eugene/Beni)
    • Test ramp to 300 A the magnet.
    • Start the run without magnetic field
  • Surveys (Tim/Mark)
    • FCAL survey
    • TOF syrvey
    • Survey beamline component (secondary collimator, etc.)
    • Survey CCAL after it's installed in the Hall
  • DAQ (Sergei).
    • Start testing DAQ
    • Power the detector, start taking cosmic data (start in the beginning of August) Needed to power the detectors.
  • Trigger (Alex S.)
    • Start checking LED (random) triggers for sub-detectors
    • Run CCAL trigger when the detector is installed in the Hall
  • Beam line
    • Install He beam pipe between FCAL and CCAL (Tim)
    • Install led shielding wall in front downstream the PS (Tim)
    • Radiator status (Tim/Hovanes).
    • Tagger hodoscope (A. Somov)
      • Repair several counters (re-glue scintillators,check electronics)
      • Calibrate baseline, run scalers
    • Tagger microscope (Richard Jones/Beni)
      • Calibrate baselines, take dark rate data
    • Goniometer (Hovanes).
    • Collimator Motion (Hovanes).
    • Active collimator detectors(Richard Jones/Alexandre Deur)
    • Profiler (Hovanes)
    • luminosity monitor (Hovanes).
    • Halo monitors
      • They have not been touched. They should be ready. To be checked.
    • luminosity monitor
    • PS system (Alex Somov)
      • Check detectors
    • Beam line magnets (PS magnet sweeping magnet and tagger quads).
    • Polarimeter (Sebastian Cole/M. Dugger).
      • Optional, not used in PrimEx
    • Targets (Chris/Tim/Alexandre D.)
      • LH4
      • Be
    • TAC (Hovanes/Alex Somov)
      • Use CCAL as TAC, use as a backup
    • Slow control (Hovanes).
      • Implement new software (features) for FCAL
    • RF (Sergei)
      • Check with cosmic trigger. Looks fine
    • Radiation monitors (Alexandre D.)
      • Operational
  • Detector systems
    • ST (Mark Ito)
      • Ready and tested (Beni)
      • Will be used for DIRC commissioning. Will remain in place for PrimEx-Eta run and used for the 4He run, but will be turned off for the Be part of the run.
      • Random trigger has been implemented (for Beni to monitor neutron radiation damage).
    • FDC (Lubomir)
      • Got cosmic trigger to get data. Things look fine.
      • Gas chromatograph installed near the gas panel. Connected to the FDC and CDD output line.
      • Chiller kept tripping. The problem was fixed by disabling an interlock. The other problem (communication. Maybe due to a IOC) went away. Reason unknown. In all, the chiller is operational.
      • Lights for the camera near the bubbler/rotameter have been set-up (Hall's lights are dimmed because of DIRC).
    • CDC (Beni)
      • Up and running.

      • Fixed a few issues in the box (01/20th).
      • Since 01/24th, everything is connected and readout with low rate trigger looks good.
      • Took high rate (LED) triggers. Looking at it. Need to keep taking LED data to set-up threshold for each channel. LED data will be taken until beam comes.
  • RSAD and ESAD Safety documents (Lubomir):
    • Documents approved and ready for shift takers to sign.
    • DIRC replied ro readiness review recommendations on 01/25th.
    • New ComCal OSP submitted and signed (the previous version expired March 2nd.)

  • Other topics?

Live Camera Feeds from the Four Counting Houses

  1. These feeds SHOULD be open and visible at all times from one of the monitors in each of the counting houses.
  2. Management cautions AGAINST opening them from other locations or offsite, out of concern for available bandwidth.
