TITLE: 03/05 Day Shift: 16:00-00:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Commissioning
INCOMING OPERATOR: None
SHIFT SUMMARY:
Maintenance roughly ended just after noon. There was single bounce work for Squeezer in the afternoon.
Initial Alignment Notes: Then an Initial Alignment was run---ALS X-arm was pretty misaligned, but Patrick was able to restore it after some aggressive slider moves (and had to wait quite a bit for ASC signals to converge before offloading). SRC was fairly misaligned and this required tweaking SR2 pointing on the AS_C PD. Once this was centered, Patrick was able to lock the SRC.
Locking Note: IR was not found. Diff Offset slider was moved to maximize TR-X_NORM (blue on StripTool), but it only made it to about 0.45. Georgia suggested we get this value to 1.0 by taking the TRX_QPD_B_SUM's offset from -1.2 to 1.0. This did the trick. The offset was returned to -1.2.
