Shift Summary

Title: 10/2 OWL Shift 7:00-15:00 UTC

State of H1: Low noise, finally

Shift Summary: Locking problems continue, packing it in

Activity log:

Ed and Jeff both had problems locking today, so I came in to poke around at a few things.

Sheila  called and suggested I try fiddling with a couple things in Guardian, so I did, but I think other things (that I never touched!) are broken, still.

7:41 loaded new gain in SWITCH TO QPDS -41111 to -80000, sat at DRMI for 5 mins then -> ENGAGE ASC
8:14 Third Try
8:30 #4, also fails
9:02 increased  Switch to QPDS Tramp, lost lock before I could try it
9:15 Trying longer TR CARM TRAMP
10:00 30 sec Tramp, gain -120000
10:20 Reduce gain to -20000, no good, AS port looked like a split mode
10:35 Packing up, revert all changes, leaving ISC_Lock in down
