1. Last 24h:
   • FCal HV scan (A. Somov)
   • 2pm-6pm: optic optimization (T. Satogata)
   • Standard production running
2. Issues
   • Optic tuning unsuccessful: background on our Harp scan 100 times larger and some of the tagger radiation monitors have twice larger signals. Scrapping is likely the cause. MCC backed-out of the new optics. Harp background and radiation monitor signals back to normal. Transmission back to the same as Monday morning (still 15% lower than at the start of the month).
   • Coherent peak shape (Beni)
3. Reports
   • Monitoring report (Thomas)
4. Plans
   • Time chart for this week
   • Luminosity study. Plan J. Stevens
   • Standard production running

1. Last 72h:
   • Friday Morning: Optic optimization
   • TAC run (Alexander S.)
   • Empty target run+ raw mode run
   • Standard production running
2. Issues
   • Rate are significantly lower after beam optimization. Diamond orientation dependence (Alexandre D.). This is due to bad beam profile: The optimization done on Friday by Todd S. did not last:
     • Harp result for Friday after the optimization
     • Harps result for Saturday 1, 2
     • Harps results for Sunday
   • GONI camera is not communicating (Hovanes)
   • FCAL pulser (Elton)
3. Reports
   • Richard made is tool to compute the beam profile available for general use.
   • Monitoring report (Thomas)
4. Plans
   • Time chart for this week
   • 30 min FCal scan (A. Somov)
   • 2pm: optic optimization (T. Satogata)
   • Standard production running
5. Discussion ComCal commissioning

1. Last 24h:

   • Check issue with CBrem gui. It appears to be gone (Hovanes)
   • Maintenance: 1pm-4/5pm.
     • Access: flux monitor (Tim); FCal (Colin)
   • Standard production running
2. Issues
   • Beam energy monitoring (Alexandre D.)
   • Shift checklist rejuvenation (Elton)
3. Reports
   • Energy dependent rho polarization for low-energy running (Alexander A.)
   • Monitoring report (Thomas)
4. Plans
   • Time chart for this week
   • Optics adjustment (Todd/Jay) 30 min.
   • TAC run this morning/afternoon.
   • Standard production running over the week end.
5. Discussion ComCal commissioning

Thursday, Nov 15 at 08:45

1. Last 24h:
   • Standard production running
2. Issues
   • CBrem gui not fitting and the coherent edge has been drifting. Decided (6am) to stop run on diamond, do Harp scan and continue with amorphous run, then TAC until the problem is fixed.
   • Convergence optimization failed because optics has drifted compared to yesterday, the basis for how to carry the optimization. Rates after optimization did not show improvement.
   • Beam current has been unusually unstable yesterday [Some fluctuations of current correlates with beam position drift https://logbooks.jlab.org/entry/3626367]
3. Reports
   • Monitoring (Thomas)
4. Plans
   • Monday maintenance is moved to today, 1pm-4/5pm.
   • Check V-wire position wrt beam (Sacha).
   • Investigate issue with CBrem gui. Meanwhile, fill the target.
   • Production running, starting with amorphous (for CBrem ref.)
   • Optics adjustment (Todd/Jay) 30 min.
     • Access to move back the flux monitor
     • Other access?
   • TAC run this morning/afternoon is postponed.
   • Optics adjustment (Todd/Jay) 30 min.
5. Discussion ComCal commissioning
   • Runplan (V.3) [2] [3] [4]
   • Week 11, Week 12, Week 13
