Wednesday Day ops shift End
TITLE: 05/28 Day Shift: 1430-2330 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Planned Engineering
INCOMING OPERATOR: Ryan S
SHIFT SUMMARY:
Epochs of locking:
When I first got in to the control room I ran a full Auto initial alignment.
This lead us to no flashes on DRMI & PRMI.
We then manual initial alignment through a few PRX steps.
Which gave us flashes, but after that we had some noise on the beam splitter oplevs.
Then a REFLAIR phase issue was overcame.
Mean while the SQZrs are turning on the laser and did some aligning on the SQZ tables.
Then unknown 70hz feature was later found out to be ISI in HAM1.
The VAC team checked HAM1 for leeks, and didn't find any.
