TITLE: 10/31 Eve Shift: 23:00-07:00 UTC (16:00-00:00 PST), all times posted in UTC
STATE of H1: Wind
INCOMING OPERATOR: Nutsinee
SHIFT SUMMARY:
Had some trouble with the MC. Sometimes Clearing History (ASC WFS) would help. Another time FSS was oscillating, so the Fast Gain was ramped down to it's lowest value and returned to 9.0. (Sheila mentioned both of these to me.)
For first attempts at locking, simply tried to lock (no initial alignment), and would lock DRMI, but it would drop out shortly after. Jenne mentioned going to LOCK_DRMI_1F and then looking at ASC ERROR signals on striptool & tweak optics for signals which have big ERROR signals.
LOG:
-
Robert continues PSL work on PZT Mirror (trying to damp & stiffen the mount we have).
-
23:10 CP3 Overfill Complete (Gerardo)
-
23:13 IMC not locking (no light on Refl PD)--investigating
-
23:26 PCal team back from EX
-
23:50 Need to steer PSL beam back onto the IMC Refl spot on the wall (Kiwamu, Robert)
-
0:05 Monthly alert siren testing 5-6pm PST
-
0:10 IMC back (Kiwamu, Daniel,
-
0:49 PI Mode10 took a step up & was at the threshold to get Verbal Alarms...probably not real, but not sure what to do about it.
-
1:04 Transitioned SEI_CONFIG from VERY_WINDY_NOBRSXY -> WINDY (nominal)
-
4:45 Left LVEA after aligning PSL input beam into HAM1 (via spot on PSL Enclosure Wall). We did this after Robert's PSL work which was damping & stiffening pzt mirror.
-
After this had a few issues with the Mode Cleaner locking (as noted above).
-
Then the ALS Glitching arose for keeping H1 one down.
-
I've passed on what I got from Sheila to Nutsinee, but if it looks like a tough night, this shift should be cut short so the ALS issue can be addressed by the morning crew.
