  • Schedule for the run:
  1. August 18 - August 26 (change detector configuration from CPP to PrimEx)
  2. August 27: beam restoration
  3. November 29: end of the run
  • Accelerator overall plan and priorities:
  • Hall D plan
    • Experiment:
    • PrimEx
    • 2 TAC Runs
    • Empty Target Runs
  • Expected Staffing and responsibilities:
    • The Run Coordinator oversees the run:
      • August 18 - August 23: 14 days: Liping Gan (detector configuration change)
      • August 24 - August 30: 14 days: Igal Jaegle (detector configuration, accelerator restoration)
      • August 31 - September 6: Stuart Fegan

        • (Last day of Primex running November 29 16)
    • The Physics Division Liaison (PDL) and Hall D Work Coordinator/Safety Warden (M. Stevens) verify that the proper safety rules are followed. PDL is:
      • PDL: Lubomir Penchev
    • 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)

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.
