Monday, February 20

  1. Accelerator Status over the last 48 hrs
    • Beam was mostly stable but with some increase in trip frequency [1] [2]
      • Apparently, to turn on/off Hall A beam, our beam has to be taken down as well for a few minutes
      • 2 downtime incidents of more than 30 minutes on Saturday:
        • Continuation of 1L23 issue Sat morning (1.5 hrs) [3]
        • Work on 5th pass separator on Sat (42min) [4]
      • No significant accelerator downtime on Sunday
    • Beam studies tomorrow: either 9:00-14:00, or 14:00-17:00
    • Harp scan on Saturday:
      • MCC scans at 5C11 and 5C11B and our scan at radiator
        • (Sigma_X, Sigma_Y) is (0.88, 0.37), (0.71, 0.28), and (0.60, 0.18). This is consistent with the previous scan 2 days ago.
  2. Hall-D/GlueX items
    • In the last 48 hours:
      • Feb 18: ABU 14.60 hrs (2.74 + 6.11 + 5.76), BANU 3.24 hrs (2.05 + 0.74 + 0.45)
      • Feb 19: ABU 18.22 hrs (5.92 + 6.06 + 6.24), BANU 2.42 hrs (0.70 + 0.83 + 0.89)
      • Feb 18: Total triggers collected: 1648 M
      • Feb 19: Total triggers collected: 1720 M
    • 2 parasitic TRD runs have been taken with different radiators.
    • Trigger studies were performed by Sascha both on Saturday and Sunday
  3. Issues
    • Once, the goniometer got stuck moving, and Hovanes had to fix it [5]
    • May be, related to the above - "unknown" diamond orientation [6]
    • Puzzling CSS problem with TOF FADC scalers: [7]
    • RootSpy issues:
      • "Reset" did not reset all histograms [8] [9] - Fixed by David
      • No reset of normalization for pi0 plot at "reset" [10] - Fixed by David
      • Run number on the HDMONITOR elog plots [11] is getting stuck sometimes [12]
        • Run number is now printed on the plots
    • DAQ issues:
      • Zero counting rate for some ROCs [13] 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?
  6. Offline Analysis?
  7. Any Other Business?


Saturday, February 18

  1. Accelerator Status
    • Beam was mostly stable in the last 24 hrs [18]
      • 4 downtime incidents of more than 30 minutes (and a few <10 minutes):
        • Hall A setup (30min at 4PM)
        • Hall D Orbit Drifted (37min at 6PM) [19]
        • Optics check to clear 1S00 trips (32min at 4AM) [20]
        • 1L23 (ongoing since 6:35 AM) [21]
    • BPM calibration
      • All 6 BPMs are now in sync with each other! [22] [23]
  2. Hall-D/GlueX items
    • In the last 24 hours:
      • ABU 16.73 hrs (5.80 + 5.32 + 5.61), BANU 1.73 hrs (0.28 + 0.72 + 0.73)
      • Total triggers collected: 1813 M
    • Better settings for JTV 7 Nitrogen supply valve
    • Oscillating target pressure? [24]
    • Progress on fixing random 32ns shift of TDC times [25]
    • Software issues:
      • Trouble starting Event Viewer [26]
      • CSS was unavailable for about 1 hour (network problem?) [27] [28]
      • RootSpy twice went down in an unusual mode:
        • first, for 40 minutes at 11 AM [29]
        • 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 [30]
      • 3 latest shift summary reports mention DAQ reboots only 2 times! Unbelievable!!!
  3. Monitoring
  4. Run Plan
    • Production, production, production...
    • Harp scan
    • Sascha's trigger studies?
  5. Offline Analysis?
  6. Any Other Business?


Friday, February 17

  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 at 17:30
    • Stable beam since then (max 10 minutes off on 2 occasions) [31]
    • Radiation levels are about the same as earlier [32]
    • Harp scans: MCC and ours.
      • In terms of (Sigma_X, Sigma_Y) at 5C11, 5C11B and radiator:
        • (0.83, 0.32), (0.63, 0.24), (0.68, ??? - the fit has failed)
        • Beam is ~20% tighter in X and twice narrower in Y comparing with a day ago
        • Photon transmission is about the same as a day ago
    • BPM calibration?
      • AD00 BPM is no longer the same as AD00C BCM but only 40% of it [33]
  2. Hall-D/GlueX items
    • In the last 24 hours:
      • ABU 10.32 hrs (0 + 4.54 + 5.78), BANU 2.13 hrs (0 + 1.17 + 0.96)
      • Total triggers collected: 1046 M
    • The usual DAQ and RootSpy issues make shifts entertaining
  3. Monitoring
  4. Run Plan
    • Production, production, production...
    • Sascha's trigger studies?
  5. Offline Analysis?
  6. Any Other Business?


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 [36]
  3. Monitoring
    • A new instance of 32ns ADC-TDC offset: [37]
  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?
