- Notes from the previous 24 hours:
- Beam convergence adjustment by Todd
- Beam issues off and on through Swing and Owl shifts
- fADC125 module failure in FDC. Rapid access used by Sascha and Cody to replace.
- Other DAQ issues ~1hr for swing + owl
- Issues:
- Shift-takers should at least log any acknowledged alarms so that they are not forgotten
- TAGH had few tripped channels with no alarm sounding
- High Level monitoring plots look bad (calibrations)
- Bubblers
- Shift-takers should at least log any acknowledged alarms so that they are not forgotten
- Reports:
- Run Plan
- TAC run using V-wire today (pending good AC lock)
- Production Running
- AOB

- Production running overnight
- Running until May 6 official.
- 3 month down time likely
- Issues:

- Hot channel in TAGH
- Reports:
- Rates with the 75 um and 750 um Be converters (Alexandre)
- Calibration Updates (Sean)
- Low Level Monitoring Report (Thomas)
