OPS Tuesday Day shift summary

TITLE: 05/30 Day Shift: 15:00-23:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Observing at 124Mpc
SHIFT SUMMARY:

• EY Vacuum pressure red alarm in the morning for PT-424 & PT-410, I told Travis about it, the alarms continued into the afternooon
• VAC PREP lab red 0.3 dust alarm at 17:10UTC, PSL 102 (Anteroom) red 0.5 dust alarm at 17:25TUTC & 17:35UTC. The CS wind is starting to pick up over the past hour, could be the cause?
• Ground motion is higher at both arms plus 20mph wind gusts while relocking
• DARM on NUC30 is back up and running

Lock#1:

Started off with an initial alignment after seeing some drifting on the OPLEVS, & OSEMS (esp. SR3 pitch, which seem to drift a large amount for only 4 hours). There doesn't appear to be a clear temperature correlation?

Both arms went through increase flashes, Yarm went smoothly and locked at a high 90%, Xarm struggled a bit and took more than twice as long, I tapped ETMX in pitch 0.3 microrads and it was enough for it to catch after it finished increase flashes and was still struggling on ENABLE_WFS. Good beatnotes, -4.5 (X) & -6 (Y).

SRM was badly aligned, after lots of SRM saturations and the ASC-AS_A signal was low (~2 instead of 4/5) I paused INIT_ALIGN and brought ALIGN_IFO to offload SR2 then I went to PREP_FOR_SRY and adjusted SRM mostly in pitch to make AS_AIR more symmetrical and to get higher highs, and lower lows on the H1:ASC-AS_A_DC_NSUM_OUT16 trace. I then unpaused INIT_ALIGN and rerequested SRC_ALIGN which went smoothly the 2nd try.

Lost it at FIND_IR, Yarm looked a little glitchy then it lost it

Lock#2:

Lost it at FIND_IR again, it seems like Yarm is killing it?

Lock#3:

Lost it at LOCKING_ALS, Yarm again I think

Lock#4:

COMM IR was found pretty easily, DIFF took a while, went through PRMI got it, took a little while for it to get DRMI despite good looking flashes.

Lockloss at MOVE_SPOTS 20:57, DCPD saturation right beforehand

Lock#5:

Couldn't get DRMI went through PRMI again, I had to tap PRM in pitch to catch, then in DRMI_1F I adjusted the BS in pitch

Had to stop at OMC_WHITENING for the violins to damp, IX12 & IY8 have changed phase, a negative gain damped IX12 down (-2, max of -4) instead of the +2 its set to in lscparams. IY8 also was rising, I changed its gain sign from 0.08 to -0.08 and it started to fall - Tagging SUS

Aquired NLN at 22:25UTC, we had to wait for ADS to converge for the CAMERA_SERVO as usual and some SEI SDF diffs to be checked

In Observing at 22:39UTC

DARM was glitching out a bit around 22:55 on the FOM
