Attempting to recover 2L21-6, cavity tripped on KMAI. Turned on again and noted that KMAI > 3mA and increasing. KMAS=2 kV. Turned cavity off until AES-RF can evaluate.

2L13-4 gradient recovered after allowing RF to soak for a bit at 2.3 MV/m. Walked the cavity up to 4 MV/m and vacuum continues to recover.

2L13-1 Bypassed
2L13-2 ARC faults. Good after OLT
2L13-3 ARC faults. In addition, increasing gradient causes a spike in vacuum, but falls off quickly. Holding steady at 4 MV/m though
2L13-4 CWVF faults. Vacuum degrades above 2.8 MV/m, but holds steady below that
2L13-5 Bypassed
2L13-6 Good after OLT

2L09-1 Recovered nicely. GMES ~ .05 > GSET
2L09-2 FPWR fault. Had to Open Loop tune, only got a GMES of about 1.9 before it became unstable but that seemed enough to set back to auto and walk up to GSET of 3. Currently at GSET of 4 and GMES of 3.83. Will let it sit and try open loop tuning again.
2L09-3 GMES sitting at 3.80. Open loop tuning didn't make an improvement.
2L09-4 GMES stable at 3.76.
2L09-5 Separate log entry, could not achieve any gradient
2L09-6 CWWT fault
2L09-7 Successful
2L09-8 Successful

Open loop tuning is not working for 2L09-5. Stepping the motor has no noticeable effect on the GMES or detune angle. When attempting to turn on normally FPWR spikes and faults
