Restarted the Hall C FFB controls as a step to help troubleshoot the DAC Saturation Alarms from last night.
-IOCSE14's VME crate was power cycled.
-OPS Put the FFB BPM's into FeedBack mode
-OPS stopped the FF/Slow Lock server and it restarted automatically (as designed)

OPS can execute the "Fast Feedback (FFB) Restoration Procedure" when they would like to attempt
turn on Hall C FFB.

0800 got a call about 2L03 dropping HV with a DC current overload fault. Locked it up after finding it not going to HV to check CPS for any visible damage and didn't find anything visually. Replaced Mod Anode board and ModAnode resistor for cav.8 which was problem dropping HV yesterday. After locking it up after repairs, it still failed going to HV and had DC Overload still. Pulled jumper for klystron 8 and again, failed HV with DC over current fault. Did un-bypass cavities 1 and 2 to try HV and again cavities 3 and 4 with same problems.

ITV1S01 was the last viewer inserted in the accelerator before I took a screen shot. When you insert IYG3H07, the name does not change in the blue box in the top left of the adviewer screen like the others do.
Attached is an old picture of 3H07 from December, 2024. In the top left of the adviewer screen it displays the generic "MCC Axis 1-1"

While excavating a trench for installation of the ground wire for lightning protection for the Hall B vent fence, a 1" conduit and internal conductors were dug up and severed. The circuit was a 120V AC line feeding monitoring CARMs on Halls A (RM48) & C (RM47). Work was immediately paused and the event was reported. The circuit was checked and made safe by FM&L electricians. Hall C Operations were re-authorized -- impacted CARMs not PSS interlocked so not considered defense in depth. Boundary monitors and other CARMs around Hall C (truck ramp, tunnel) remain operational.

If this is for IYG3H07, why does the image say ITV1S01?

Given the trouble starting up the FFB system in Hall C, please follow these steps:

1. Balance the 2A energy locks with the Hall C dipole string.
2. Reboot the relevant VME (I believe IOCSE14 for Hall C).
3. Put the BPMs in feedback mode.
4. Restart UNIX server.
5. (Re)start the restore/startup procedure.
