Happy Halloween!
Past 72 hours
- Friday afternoon TOF HV module failed, replaced (Beni/Sasha)
- Beam returned early Saturday morning and was smooth most of the weekend

Plan
- Production running on full target until Monday afternoon or Tuesday morning
- Request for raw mode running with beam (none for PrimEx yet) -- Monday after Sasha confirms configuration file
- Calibration of CompCal modules with adjusted HV, 1 hr at low intensity -- postponed to Thursday (after maintenance)
- Accelerator: Hall A pass change and maintenance day (access) on Wednesday this week
Friday, October 28
Past 24 hours
- Returned from RF recovery around 6 pm, postponed CompCal calibration run to Friday
- Harp scans performed when beam restored
- Production running until midnight: "smoking gun" for burnt RF power supply
- FDC chiller interlock
Shift Summary
Issues/Reports
Plan
- Recover from accelerator power supply issue by "early afternoon"
- Calibration of CompCal modules with adjusted HV, 1 hr at low intensity (Sasha)
- Production data with full target

- Harp scan after beam is restored, more than a week since the last one (Alexandre)
- Calibration of CompCal modules with adjusted HV, 1 hr at low intensity (Sasha)
- Production data with full target
