2L24 cavities 5,6 and 7 are pulling soft faults on PLDE and difficult to operate these cavities. After looking at the waveforms all the cavities have a 45 Hz component in detuning. I also noticed this on all cavities, but to a lesser extent. Cavities 5,6 and 7 have harmonics of 45 Hz too
This sounds possibly like a pump, but not sure which one. There was some girder work done between 2L24 and 2L25 during SAM? It might be work checking downstairs physically.

Once the PTW is on-issue this task is approved. Please coordinate with Ops before testing repairs / powering on. Ops can deliver beam to FC2 in parallel with powering on supply, and many FC2-limited beam studies are on the schedule.
