Recently started to frequently mismatch. Always retakes setpoint fine when asked.

This is an Arc 9 lock corrector for whomever cares.

When we tried to send back to the Hall after they finished setting up, we were tripping BLA immediately. Sent tune beam to the 1R and found energy was way off and the beam spot looked squished. We had to adjust the NL GP almost +6 degrees to get back most of the energy. Checked SL GP too, and that was adjusted -2 degrees. Checked Pathlength to C dumplet, but that looked good.

We were able to send back to the Hall after pulling the dumplets.

Phase seems to have slipped in the North

Summary:
After Hall C finished their target/config change, we were unable to get beam out of the injector. Checked GP (adjusted and fixed) and path length.

Cavity kept tripping out of SELAP. POFF optimiation seemed to have helped.

Contacted RF on-call for guidance. We were advised to ensure the RFCM is fully seated in the rack, then clear the limit fault on the quick check. Gave it a good push, cleared the limit fault, and it looks clear now! We'll keep an eye on it nonetheless.

Edit: Unfortunately the no xrate alarms came back for this channel. Not sure we can do any further troubleshooting on it tonight, but it doesn't appear to be causing immediate issues.
