RF on call has been paged. We attempted to bring the zone down to filaments and back up. When that didn't work the guidance suggested restoring the IOC which did the trick. Had to do a POFF optimization and lower the GLOS on cavity 8

1L13-1 OLT Odd Detune Angle Behavior

21 hours 22 minutes ago
Log Number: 4535669Logbook(s): Entry Makers: bjacobBody: 

When bringing back 1L13, cavity 1 was struggling. A quick OLT did the trick.

I did see a weird drop in gradient /jump in detune angle. Specifically, it went from 7 MV/m to 2 MV/m and detune angle jumped from -5.3 to 52.2 with a step change of only 250. Just some odd behavior. It didn't prevent me from bringing the cavity back on but I figured somebody might want to look at this.
