This cavity gave us a few trips so we figured a POFF optmization was in order. I decided to try Cold RF ON and see if that was able to quickly fix our problem. It only made a minor adjustment to POFF but we'll keep an eye on it and see if the cavity is looking better.
Figure 1: Initial beam into SL not quite making it to 2L10 BPM.
2L05 was recovered since last beam through SL, so starting with it's zone gang phase first. Figure 2. Then, moving on to SLGP.
Moved about 100deg of SLGP, slowly gaining more and more BPMs, all the way to 2L13. But then tripped 2L13 BLVF. Typing this up as we wait for vacuum to recover.
All adjustments done in Figure 2 were w/VL-mode from C-laser.
Figure 3: Getting towards the end of the linac. Figure 4: At the end of the SL, now trying to maximize 2S BPM wiresums by adjust SLGP. Figure 5: Current orbit through 2L.
