The issue in the SL has calmed down again. I'm still monitoring it and communicating w/ ops as appropriate. I started noticing this issue earlier this month, installed measurement hardware, and took baseline readings while the system was healthy. To investigate further, I'm putting together a plan to look at things in more depth at the next opportunity.

Fast feedback on in position mode, intend to LEM NL & SL at next HC target change to see if we can apply RF control as well

Dropped the zone out of High voltage on ModAnode current high fault. HV and RF recovered without issue

Decarads in place on 1L24 and 1L25; would like to start pulse processing on those zones on next available maintenance day.

Please check drive levels when convenient. I believe there is either a bad rfcm or weak amplifier in this location. Cavity history lists as quench limited at 9.4, but has been derated from 9 all the way down to 7 for regulation/SOSing. Klystron should have more than sufficient power at those gradients to not encounter beam loading.

Running smooth. Seeing some GLDER warnings in the South Linac.
Pushed 1L11-5 up to 11.4 MV/m

Not sure what's the cause. Started tripping BLMs. Ran tune beam to dumplet. PLDERs cleared some. Resumed beam to Hall C.

RF recommended trying to push this cavity again while monitoring vacuum. As long as it stays below 1e-7 it's ok. Didn't even come close to that so we'll update the ODVH.
