Shift Summary - Owl
TITLE: 10/11 Owl Shift: 07:00-15:00 UTC (00:00-08:00 PST), all times posted in UTC
STATE of H1: Lock Aquisition
INCOMING OPERATOR: Cheryl/Corey
SHIFT SUMMARY:
Everything went relatively well. Had some pretty decent lock stretches. Would have maybe stayed locked the entire shift if PI commissioning wouldn't have broken the first one. I didn't experience any of the 45MHz issues that Patrick had on his shift. Aside from some basic re-aligning, I only had to deal with some small PIs and a litle bounce ansd Roll damping
LOG:
11:44 NLN ~50MPc
12:55 damped PI mode 17 by by adding another -60 degrees to the phase.
12:58 Had to damp ITMX Roll mode. Changed phase to -60 and set the gain to 20.4 (incrementing as directed in the Wiki)
13:00 restarted/reset all FOMs
13:38 added another -20 degrees to the PI mode 17 phase. (-130 degrees total)
