keyword=MUST READ FOR SHIFT TAKERS: CALO block #105 HV off for ~16 hours
During the last 16 hours (since thursday's beam studies+ beam recovery which took till midnight or so), block 105's HV seemed to be off. This is a channel which was swapped very early from Mainframe 8 Slot 8 channel 9 to same Mainframe, Slot 15 channel 11.
This was possible since the alarm handler was not updated to take this channel off as an error. It will be updated ASAP. In the meantime, shift takers should take snapshots of the calorimeter HV every shift (along with the proton array HV) and CHECK that channel 105 plugged in "Cal-15 Ch11" in the GUI is non-zero !!!!
