  1. Accelerator Status over the last 24 hrs
    • Beam was mostly
      • Stable until midnight
    • Harp scans:
      • Beam was re-focused around noon ELOG
      • final MCC scans : IHA5C11, IHA5C11B
      • Radiator HARP scans: Radiator Harp
        • (Sigma_X, Sigma_Y) is (0.85,0.55), (0.65, 0.49), and (0.73, 0.43).
      • new Harp scans as part of beam steering problem: MCC, Radiator Harp
  1. Hall-D/GlueX items
      • Downtime incidents of more than 30 minutes:
        • DAQ 10:45 for about 40 min. , Sergey helped
        • Beam position lock on active collimator steered the beam away: 00:15
        • Traced problem to pre-amp problem in inner AC (dead or needs to be reset, power cycled ?)
        • Total triggers collected: 1400 M
  2. Issues
    • Active collimator
    • DAQ issues:
      • difficult restart at 10:45pm
  3. Monitoring
  4. Run Plan
    • Repair active collimator.
    • HIgh luminosity ?
  5. Offline Analysis?
  6. Any Other Business?
