TITLE: 08/27 Day Shift: 1430-2330 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Planned Engineering
INCOMING OPERATOR: Corey
SHIFT SUMMARY:
Elenna's current Manual Initial Alignment steps:
Get ALS Gaurdians for Y arm to ETMS WFS OFFLOADED [13], (except X arm is messed up so only for Y arm currently). ETMX was left in Locking [-23] and ETMX and TMSX were touched up to maximixe the ALS-C_TRX.
Then once they are locked and stable. unlock them.
COMM Beatnote was 6.5
DIFF was -9 ish
Then use ALIGN_IFO to start a manual Initial alignment. But we cannot use ASC at all because the diodes need to be "rephased" something about the sidebands are all different now.
This means we take ALign IFO to AQUIRE_XARM_IR[11]. Once that is done.
We go to Aquire PRX. Moved PRM to to maximize ASC-AS_A_DC_NSUM.
Then went to Prep_for_mitch[41] > mitch dark locked and moved the beam splitter while watching the AS Air cam for maximum darkness and a ring around a center dot.
SR2 Align[58] was ran and automatically worked. Which uses a QPD and does not need sidebands.
Moving SRM while in SRY_LOCKED[62] to maximize ASC_AS_A_DC_NSUM.
AS_CENTERING[77] also ran with out intervention.
Then take the power back down to 2 watts.
We are ready to try locking!!!
The Verbal Alrams did a weird thing today. The VAC Alarms sounded off for PT-134 , PT152, and PT-180...
I called Travis over to come check it out and he said everything looks fine.
PT-134 is tripped due to someone's phone tripped it a while ago.
PT-152 is correctly telling us the pressure because that sensor is indeed at atmospheric pressure between HAM 5 and 7.
And PT-180 was replaced on tuesday but it's new channel name is PT-180_MOD2 now instead of MOD1.
Which brings up the great point that the Verbal's VAC alarm channels need to be updated.
PEM note:
A garbage truck slammed a garbage dumpster on the ground around 22:49 UTC today. It was felt in the ground by multiple staff's highly calibrated foot seismometer.
Craning over X arm never happened because they ran out of time. Even if it is mentioned in the Reservation system table below.
