MYR9R03 Looking Good

Log Number: 4527612Logbook(s): Entry Makers: moserBody: 

Conductor monitored by T21 was the one of concern, rising ~5C last week. It has not risen further after a full weekend of operation. It, along with T11, are the only two of 24 >50C, but are holding at <55C. No concerns with MYR9R03 over-heating at this juncture.

Weird issue with xC FFB BPMs

1 day ago
Log Number: 4527560Logbook(s): Entry Makers: victorcBody: 

Had trouble reengaging Hall C's FFB after a target change. Could not get a "Gain OK" after performing a gain search after Hall C made it to their requested current. After another gain search attempt, the 4 FFB BPMs shown in figure 1 went in to alarm. Didn't catch the actual fault on the live display before they cleared. It wasn't until the final gain search attempt (there were several - see plot) did the BPM wiresums look nominal (all around 10) and gain was found to finally be OK.
