-
No beam for the entire shift
-
Dump of pilots from power converter fault of RQ7.R4B1 (again - free wheel diode water flow). Access to fix water flow meters
-
As part of the intervention, the UPS (EOK103/47) got disconnected and caused problems in S45 (loss of communication with ~20PCs) and in P4 (loss of cryo cards and the 2 BLM crates). The root cause of the issue is not clear
-
Cryo needs another access to P4 to replace a broken card (following the power cut) on the DFB.
-
Intervention in P4 was not successful, putting the machine in power-save mode
-
RF and cryo issues are resolved
