State of H1: locking well, OAF issues
Activities:
-
all locking attempts made it to NLN
-
all NLN attempts included waiting in Noise Tunings for at least 15 minutes
-
OAF has died multiple time
-
One lock was saved when OAF came back and I was able to damp PI mode (no modes were ringing up when OAF died)
-
I suggested we might save more locks if the PI mode damping was down as short a time as possible
-
Jim reorganized the OAF restart script to kill the PI process last, and restart the PI process first, to minimize the down time
-
I've taken H1 out of lock twice today to accomodate invasive OAF work
-
one lock loss was during the earthquake at approx. 22:00UTC
Currently:
-
fire department is at MX to look at their fire pannel - it didn't respond to the daily query
-
Fil and Jim are here and trying another change on OAF
-
OAF is currently down
Cheryl's idea was very clever; we now have ~1 min PI damping downtime which is no problem and have made it through several restarts without PI being a problem.
