1. Notes

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) [1] [2] [3]
   • Week 11, Week 12, Week 13
