TITLE: 05/04 Day Shift: 15:00-23:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Commissioning
SHIFT SUMMARY:
Main Notes:
- IFO is locked at NLN for ~2:45 hrs and measurements are currently ongoing
- Still some SDF diffs in the observe snaps preventing us from going to OBSERVING (though most are due to ongoing work)
- GRD was able to do most of the locking automation with the exception of DRMI, where I had to intervene in ACQUIRE_PRMI
- LOCKLOSS @ 14:35 UTC, DCPD saturation, then again trying to relock at LOCKING_ALS, not sure why
- Held at LOCKING_ALS to allow TJ for automation work on IR locking
- Lock #1:
- Acquired NLN @ 16:51 UTC
- IN OBSERVING: 17:17 UTC
- OUT OF OBSERVING: 17:26 UTC
- PI24/31 ringups
- LOCKLOSS @ 18:28 UTC - PI ringups
- Lock #2:
- Had to intervene at DRMI (after GRD failed a few times) to catch PRMI by moving PRM in Yaw (~20 microradians)
- Stopped at ENGAGE_ASC for measurements
- Jeff ran a broadband PCAL measurement on EX
- Acquired NLN @ 20:12 UTC
- Ryan S did some ISS second loop off for testing
- EX saturation @ 21:34 UTC - Probably CAL related - and again at 22:13 UTC
- Other Notes:
- Unmonitored ALS POL step size channel - Screenshot attached
- PSL DM counts - room 101 300 nm alert - trended at was ~320 counts and has been slowly creeping up over the past 4 hrs, Screenshot attached
- Vicky reverted the PI damping guardian to old working settings (success)
