Cryo reports that they are still investigating why the cold compressors keep tripping off. They are swapping some control cards and will attempt again in 30 minutes or so.

Since we're down for (presumably) hours anyway, we are going to enter the linac to take opportunistic thermal images of the arc 5 & 9 dipole strings.

The Alarm Handler monitors some of the SRF VIPs in the Injector, but the point at which it goes into alarm seems to differ from the Injector SRF vacuum screen. Originally this log entry was supposed to be about VIP0L05B, but while I was writing it, the same thing happened for VIP0L06A and VIP0L05A. All three valves were in alarm in the Alarm Handler, but were showing no alarms/faults on the vacuum screen.
Also while writing this entry, VIP0L01 went into alarm in the Alarm Handler AND showed up on the vacuum screen. All valves have the same HIHI limit of 1e-7.
