State of H1: Low Noise, A2L measurements finished, now in Observe
JeffK and I talked to LLO, and they are working on a measurement, and expect to be back in Observe soon.
Help with Mantenance and Relocking: Kiwamu, JimW, Ed, JeffK, Jenne
Relocking Details/Issues:
-
MICH DARK did not lock. It WAS well aligned, but would not catch. MICH DARK is needed for end of O1 calibraitons, so some effort to lock and or diagnose the issue was made, and not successful.
-
H1 broke lock at ENGAGE_ASC twice, and JimW offered that sitting in each part, part 1, part 2, and part 3, and waiting for ASC signals to settle each time, has helped get H1 through those steps. This issue and the necessary work around are new in the last two weeks.
-
H1 then stalled at engaging the ISS 2nd Loop, which had to be engaged manually.
Currently: H1 in Observe at 23:24:36UTC, and as of this alog, range is 80Mpc.
Ops Day Summary: 16:00-23:59UTC, 08:00-16:00PT
State of H1: Observe for 44 minutes, range is 80Mpc
Current state of the site:
I just notinced that CP3 LT200 is again 0!
It seemed to be working again earlier today, but seems to have failed again, or something.
There's an earlier algo/alogs from VAC with more info.
