- The EX GV20 AIP was not functional since Sunday (for details, see aLog https://alog.ligo-wa.caltech.edu/aLOG/index.php?callRep=78339). The controller was replaced, and since the pump lost functionality, the pressure in the Annulus system built up, so it was pumped out with a Pfeiffer aux cart. After reaching ~2E-5 Torr, the pump came alive again. The pumping cart was switched off, disconnected, and the AIP was able to hold and decrease the pressure further. - The HAM2 AIP seemingly was not functional since last Wednesday (06/05). It was found that the issue was with the communication cable. The cable was disconnected, then reconnected, and the signal came back.
