  1. Accelerator Status
    • Hall was in controlled access from 7:00 till 16:30 for RF separator studies
      • Work on TRD GEM by Kondo during this time
      • Alexandre has retrieved supplemental dosimetry from the tagger
      • Production restarted from 17:30

    • Radiation levels are about the same as earlier [1]
    • Harp scans: MCC and ours.
      • In terms of (Sigma_X, Sigma_Y) at 5C11, 5C11B and radiator:

Thursday, February 16

  1. Accelerator Status
    • Stable accelerator running over the last 24 hours
    • Harp scans:
      • MCC scans before and after Todd's script
        "Good enough -- horizontal convergence is nearly spot on, and vertical convergence is a little shallow but ok."
      • Our scan: before and after Todd's script
      • In terms of (Sigma_X, Sigma_Y) at 5C11, 5C11B and radiator:
        • Before: (1.31, 0.63), (1.08, 0.73), (1.03, 0.41)
        • After  : (1.07, 0.51), (0.79, 0.50), (0.78, 0.32)
    • Convergence studies from Hovanes: Feb 15 vs Feb 9
      • Beam sigma at the radiator: 0.6cm (Feb 15) vs 0.5cm (Feb 9)
        "... uncertainties ... a lot larger compared to Feb 9. It is hard to make any conclusions about the improvement of the spot."
    • Work on RF separation will start at 7:30 AM today and last for 2-3 hours
  2. Hall-D/GlueX items
    • In the last 24 hours:
      • ABU 17.66 hrs (4.97 + 6.37 + 6.32), BANU 2.21 hrs (1.27 + 0.40 + 0.54)
      • Total triggers collected: 1856 M
    • A usual assortment of DAQ crashes
    • RootSpy tips:
    • New BCAL gain constants in ccdb [5]
  3. Monitoring
    • A new instance of 32ns ADC-TDC offset: [6]
  4. Run Plan
    • 7:00 AM - 7:30 AM ==> Hall safety walk-through (After RADCON does it job)
    • 7:30 AM - about 10 AM ==> MCC works on RF separation
    • A new harp scan after RF separation work is done
    • Production data
  5. Offline Analysis?
  6. Any Other Business?
