GSET-0 2L09-1
Cavity tripped and was struggling to recover so I tried an OLT. I found that the detune angle had a very large change but I got it to where I think it looked happy.
When I put the tuner back into auto and tried to walk it up, for some reason the tuner wasn't making any steps. The tuner thought it was moving as the "tuner moving" pop up would appear on the OLT screen but it wasn't actually making any changes.
We'd been struggling with this cavity for long enough and we have the head room so I GSET-0 the cavity, re-LEMed and moved on.

Corner Steering at 4R to Fix Loss
See linked Elog for noted 4R10 scraping.
We were losing the beam here when we were trying to run FOpt so it needed a touch up. Found that a combination of 4R vertical correctors and roll over shunt (MXV4R04) adjustments got a cleaner launch into the linac. It isn't perfect but hopefully it helps with the loss.
