Noticed this cavity struggling to regulate. Tuning constantly, very unstable CRFP/GASK. I thought an open-loop tune would help but there's something strange about the resonance. KRRP started to climb rapidly as soon as I closed the loops, so I've GSET this cavity 0 in order to protect the klystron.

I was able to get some of the cavities above their ODVH with ease. There may be more gradient available in this zone for someone to discover later.

Reloaded the design values since setup_345 got put back up, keeping the 0L match previously established. I'll attempt a match at the 0L10 harp backpropagating to the 0L06 quad in the setup_345 qsUtility workspace.

I was able to verify reproducibility in optics, collinearity, and transmission. The one possible issue is that the Bunch length seems to be too large at higher currents. Past 40 uA, I could not reduce ILM0R03 via steering, so I checked adjusting the prebuncher. Changing the prebuncher from 5 to 5.7 dropped the rates down to zero, reduced the current on the master slit and A4, but increased A3 and I was able to make it reliably to 60 uA. I put the setting back, and decided the set up was good as is from the all save (#26622). I will discuss with injector SMEs to see what setting would be best.
