After tuner issues and 2.5w robbed and re-installed, unbypassed to check and found no KCCU on cavity. This will need opened and klystron jumper re-installed. Re-bypassing it on State Page only, still stepped off. Also documenting iir2 vacuum interrupt/P1 FSD faults turning on RF (RFCM most likely since I don't see vacuum problem without RF when turned on at 0 Mv/m. ).

CRFP fluctuacting above 3 Mv/m with very little drive and 0.5 db RATN. Replaced the RFCM even though it had a -7dbm output (great) thinking it might be a phase regulation problem but it still had same issue with bad regulation above 3 Mv/m. Leaving the cavity set at 4 Mv/m until 2.5w amp and drive cables can be checked/replaced since it is stable at 4 Mv/m now. If it beam loads, might need to turn it down to 3 Mv/m again.

In addition to the injector quads that were deliberately changed after Yan's injector setup, five in AS/AT were. Those five are now on design. I haven't checked the time they were taken off design.

Body: COMMENTS: RFCM replaced due to CFQE problem but drive upconv. was good at -7 dbm. Low drive in cavity means 2.5w needs checked/replaced. 3 Mv/m max with 0.0 db RATN.

Following up from the HPA cooling fault on owl shift, RF investigated reports of ~1 in of standing water in the 1L06 HPA cabinet. The source of the cooling fault was attributed to an LCW flow rate set a little too close to the trip point, and increased up to a healthy 55 GPM. The water was determined to be from standing water found outside the back of the service building leaking inside and pooling in the cableway and HPA. Facilities has been informed about the standing water outside.

Trying to reproduce the 6/6/26 setup, log #4509021.
Note: VWien calibration has changed, setpoints are going to be several percent lower than before for the same spin angle.
Also, we can't restore blindly because of spot move, phase changes, etc. To avoid repeating the setup from scratch, I'll import only the INJ-I magnets from save #27283 (VWien at 23.25 degrees per the calibration saved at the time, HWien off) but exclude MBH2I00H/V and MBH2I00AH/V.

No problems found at MQNAT08 power supply output cable. Further investigation will be needed similar to MQK5R09. This work will happen on a maintenance day and will be covered in another Atlis.
