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).

- Friday Morning: Optic optimization
- TAC run (Alexander S.)
- Empty target run+ raw mode run
- Standard production running
- 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)
- 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:

- No meetings this week end.
Thursday, Nov 15 at 08:45
- Last 24h:
- Standard production running
- 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]
- Reports
- Monitoring (Thomas)
- 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.
- Discussion ComCal commissioning
- Notes
