  3. Issues
    • Once, the goniometer got stuck moving, and Hovanes had to fix it [15]
    • May be, related to the above - "unknown" diamond orientation [16]
    • Puzzling CSS problem with TOF FADC scalers: [17]
    • RootSpy issues:
      • "Reset" did not reset all histograms [18] [19] - Fixed by David
      • No reset of normalization for pi0 plot at "reset" [20] - Fixed by David
      • Run number on the HDMONITOR elog plots [21] is getting stuck sometimes [22]
        • Run number is now printed on the plots
    • DAQ issues:
      • Zero counting rate for some ROCs [23] while occupancy plots are normal
      • Sergey did ~30 min of DAQ testing during on Saturday
  4. Monitoring
  5. Run Plan
    • Production, production, production...
    • Do we need an empty target run on Tuesday?

      • RootSpy twice went down in an unusual mode:
        • first, for 40 minutes at 11 AM [39]
        • and from about 1 AM to 6 AM due to stalled gluon118
        • plus a few restarts in accordance with standard prescriptions
        • In 3 runs in a row, reconstruction efficiency was 20%, 30%, 50% of the template [40]
      • 3 latest shift summary reports mention DAQ reboots only 2 times! Unbelievable!!!
  3. Monitoring
  4. Run Plan
    • Production, production, production...

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)

    • A usual assortment of DAQ crashes
    • RootSpy tips:
    • New BCAL gain constants in ccdb [46]
  3. Monitoring
    • A new instance of 32ns ADC-TDC offset: [47]
  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
