Current Status
- Waiting for a sweep so we can go to controlled access
Current Run Plan
- Configuration change to kinematic x60_2 when the network issues are resolved. Continue to run plan.
- Possible Moller measurement tomorrow afternoon once the magnet is cooled.
- Completed energy measurement at the start of owl last night https://logbooks.jlab.org/entry/4229124
- BCM calibration completed at the end of swing shift last night up to 40uA https://logbooks.jlab.org/entry/4229041
- HMS dipole wouldn't turn on last night (initially) so we made an access. Joe found that the multi-phase switch was broken and was able to jumper around the switch https://logbooks.jlab.org/entry/4228976
Notices in Effect for Shift Crew
- Ln2 levels are fluctuating since yesterday. Not a problem, it just takes time to stabilize. Heidi is monitoring: https://logbooks.jlab.org/entry/4229205
Current Issues
- Everything on hallgw not working in the counting house https://logbooks.jlab.org/entry/4229248
- LV problem in Cal and FADC swap needed. Ben Raydo is notified and will come when we are ready for the access https://logbooks.jlab.org/entry/4229163
- Serious degradation of the photocathode probably contributed to the low polarization Hall B measured. Plans are being discussed about how to proceed with the gun in its current state.
- We powercycled the HMS camera on the angle to clear it https://logbooks.jlab.org/entry/4229299
- There's some ongoing issue with cryo and PLCs https://logbooks.jlab.org/entry/4229298
Planned Accesses to the Hall
- Will access the Hall this morning to fix the LV problem and swap an FADC.
Planned Accelerator Configuration Changes
- None
