1L23-1 FE Onset

Log Number: 4470886Logbook(s): Entry Makers: kpriceBody: 

Delayed start on this one because I initialized Decarad prefixes for 2L23 at first. Then only got through measurements on one cavity before losing HV in the zone twice since bringing it up. Progress is progress!

Cavity 1 - Over 5000 counts on Decarad 09 at 13.4 MV/m.

Decarad HV has been turned off and GLOS for cavity 1 has been restored to initial value.

Follow-up Re: Hall C ODH alarm

Investigated OM03 monitor region with the help of OPS in Hall C and the area looked clear and event free. The adjacent OM02 monitor is reading fine, so we bypassed OM03 and will investigate it further on monday.

1L23 drops HV on high cathode current in bypassed cavity

1 day 21 hours ago
Log Number: 4470883Logbook(s): Entry Makers: kpriceBody: 

Cavity 8 is bypassed for want of a filament board, but still somehow tripped the zone out of HV twice on high cathode current. All bypass bits are set correctly and I don't see where the KCCU spikes could have come from since it was bypassed just before 02:00 with the script. Related to cavity history entry on 15 Jan (fig 2)/is this what the replacement filament board is meant to correct?
