Issues
- MSTB5C (Hall D dipole) Tripped off , MTSB5C Status - Accelerator needs to fix the magnet .
Pending:
- Issues with the TAGH HV module (Sasha) - Need to replace the board in this slot again, probably Tuesday.
- Start Counter (Beni) - We do not understand why there is a mismatch in the software between start counter and tracking.
- BCM calibration. Accelerator instrumentation group informed us that last BLA calibration was done in 2021 (beside that done Thursday, 01/19/2023? To be confirmed) and recommend Ops to do one at each start of the run period. PD will keep in contact with us on how to proceed.
Plans
- Wait for the magnet fix. Go to beam permit today.
- High intensity running ???.
- RF recovery on Tuesday. Try to raise Hall A & C currents on Wednesday and possibly Thursday.
- Production (300 nA, 2h runs) with cycle:
- 2 runs para(0/90)
- 2 runs perp(0/90)
- 2 runs para(45/135)
