TITLE: 03/13 Day Shift: 1430-2330 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Planned Engineering
INCOMING OPERATOR: Ryan C
SHIFT SUMMARY:
The Commissioning crew today were focused on trying to get PRMI locked and stable for most of the day. Thye touched up the REFL A alignment which helped.
But there seems to be some power lost somewhere.
This spreadsheet was created to document the difference in the ratio of IMC Trans power/IMC input power back in the O4 run and now. Specifically when the PSL is set to 2 Watts. Feel free to update this in the future.
The Gain for H1:ALS-C_TRX_A_LF_GAIN has been bumped from 1.5 to 3 to get past FIND IR without issue.
This may not be the only gain that has been turnt to 11 to get DRMI to almost lock today, Sheila will be posting an alog later with some laser power acounting that may shed more light on that situation. Yes the Pun was intended.
