<- Back to Run Coordination Meetings: Spring 2017 Run

Friday, February 10

  1. Accelerator Status
    • Difficulties on Day Shift and into Swing. Owl smooth
  2. Hall-D/GlueX items
    • Running last 24 hours
      • ABUs 9 hours
      • Triggers
    • Coherent Peak Position
    • Harp scans
      • If the beam returns from a down or if it's beam 2 days since the last scan.
  3. Run Plan
    • Production
  4. Offline Analysis?
  5. Any Other Business?

Thursday, February 9

  1. Accelerator Status
    • Slew of difficulties over Owl shift, pathlength drift, electronics problems, BPM problems
  2. Hall-D/GlueX items
    • Running last day
      • ABUs
      • Triggers
    • Coherent Peak Position difference
    • 50 kHz running
      • Smooth running, hodoscope up to 5.7 GeV turned off. Occasional glitches in the DAQ rate due to Java garbage collection (adding a few percent to deadtime.) 900 MB/s
      • What is the data quality? (Normalized to trigger) Physics signals, (omega, rho: # per trigger, widths, backgrounds)
    • Monitoring
      • Low level monitoring coordinator (Thomas): Report every morning.
      • High level monitoring coordinator (Alex): Report every morning.
      • Cut on triggers for monitoring
      • Run DAQ when beam is gone
      • Threshold for alerting experts?
        • Run coordinator should be called for problems that limit data taking
    • Target IOC problem overnight
      • Reboot should be done by shift crew if they know how, otherwise call Deur, then cal Ito.
    • End run script and RCDB entries
  3. Run Plan
    • Align coherent peaks?
    • Production
  4. Offline Analysis?
  5. Any Other Business?
