TITLE: 01/02 Day Shift: 16:00-00:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Corrective Maintenance
INCOMING OPERATOR: Corey
SHIFT SUMMARY: H1 is locking well, but not making it to NLN
LOG:
- alignment handed off from Ed has locked all day, only one adjustment
- around 22:30UTC, I saw a pitch offset when locking DRMI
- I ran guardian through the PRMI_ASC, which corrected most of the pitch
- DRMI is locking well, some pitch is still visible, likely SRM
- I wrote a matlab script to check all SEI HEPI and ISI TRAMP setings
- I confirmed that SPM values have been in use 7 days ago, and 14 days ago
- all settings that I confirmed are accepted in SDF
- FSS has unlocked and been difficult to relock a couple times today
- the first time was 18:35 to 19:06
- Keita changed H1:PSL-FSS_TEMP_FIXEDRAMP_MIN from 0.3 to 0.35
- this worked, I saved it in SDF
- second time, 22:21 to 22:30, the traditional fix of toggling autolocker worked, eventually
NLN!!! Violin gains increased on the 4 modes in the attached plots, temporary, will revert next lock.
