TITLE: 11/25 Eve Shift: 00:00-08:00 UTC (16:00-00:00 PST), all times posted in UTC
STATE of H1: Lock Acquisition
OUTGOING OPERATOR: Ed
CURRENT ENVIRONMENT:
Wind: 22mph Gusts, 15mph 5min avg---> Hoping it doesn't get windier!
Primary useism: 0.06 μm/s
Secondary useism: 0.66 μm/s---> this is pretty high. Hope it stays flat or (obviously drops)
QUICK SUMMARY:
-
Arrived to see Kiwamu & Ed taking H1 to NLN eventually.
-
PRC Gain at 29, so no PR3_REFL_WFS step in Guardian (must be 30 or more to attempt it. This trace is the cyan trace on front Strip Tool))
-
Appear to still have issues with SRC1 Loop in that POP90 tends to be driven higher. (when this happens, zero the gain in SRC1 P&Y & tweak SRM to minimize POP90 (bright green trace on front StripTool).
-
Had a lockloss and back up now. Robert is out trying more Injections.
-
Took two attempts to make it to NLN
-
First attempt required BS tweak at Check Fringes & BS/PRM tweaks at LOCK PRMI.
-
Kyle also tiptoed out around BSC8 while attempting lock.
-
Jim was here addressing SEI system. Because we are in a bit of a noisy seismic state (fairly high useism & winds over 15mph), we are almost at a state where the current ISI_CONFIG will be pushed beyond its control. Currently running at: WINDY_NO_BRSX_V2 (a new state).
-
Continue to NOT have BRSx (this is due to ring up from yesterday). Jim may address tomorrow....or Tues.
-
So we want to run in states which DO NO use BRSx
-
Had PSL 0.3um MAJOR alarm in the 100s (but this is probably tied to windy day).
