1. Accelerator Status
   • Beam was mostly stable in the last 24 hrs
     • 4 downtime incidents of more than 30 minutes:
       • Hall A setup (2hrs)
       • Hall D Orbit Drifted (37min) [1]
       • Optics check to clear 1S00 trips (32min) [2]
       • 1L23 (ongoing since 6:35 AM) [3]

1. • BPM calibration
     • All 6 BPMs are now in sync with each other! [4]

1. 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: M
   • Better settings for JTV 7 Nitrogen supply valve
   • Progress on fixing sadden 32ns shift of TDC times [5]
   • Software issues:
     • Trouble starting Event Viewer [6]
     • CSS unavailable for about 1 hour (network problem?) [7] [8]
     • RootSpy twice went down in an unusual mode:
     • first, for 40 minutes at 11 AM [9]
     • and from about midnight to 6 AM due to stalled gluon108
     • plus a few restarts in accordance with standard recipies

1. • The usual DAQ and RootSpy issues make shifts entertaining
2. Monitoring
3. Run Plan
   • Production, production, production...
   • Harp scan
   • Sascha's trigger studies?
4. Offline Analysis?
   • Preliminary flux estimate
     • From ~1.0*10⁷ to ~1.2*10⁷ for different diamond orientations at 100nA
5. Any Other Business?

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) [10]
   • Radiation levels are about the same as earlier [11]
   • 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 [12]
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
   • 32ns TDC-ADC offsets:
     • rocid39 slot 13 for run 30614 [13]
     • rocid33 slot 4 for run 30620 [14]
   • Low Level Monitoring Report (today)
   • Low Level Monitoring Report (Feb 16)
4. Run Plan
   • Production, production, production...
   • Sascha's trigger studies?
5. Offline Analysis?
6. Any Other Business?

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:
     • Restarting cMsg server
     • Multiple instances of RootSpy on gluon47
       "... no more than 1 or 2 instances running in the counting house at any point in time."
   • New BCAL gain constants in ccdb [15]
3. Monitoring
   • A new instance of 32ns ADC-TDC offset: [16]
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?
