STATE of H1: Lock Acquisition
OUTGOING OPERATOR: Ryan S
CURRENT ENVIRONMENT:
SEI_ENV state: CALM
Wind: 5mph Gusts, 3mph 3min avg
Primary useism: 0.02 μm/s
Secondary useism: 0.37 μm/s
QUICK SUMMARY:
I got a call to help H1 get relocked. When I logged in to start helping we were in POWER_10W.
Once we reached NOMINAL_LOW_NOISE ... we lost lock before Observing can be reached.
Once H1 Got past DRMI_1F I tried to get some Z's.
Allowing the H1 some time to relock, once it got back to Nominal_low_noise again the SQZ manager was stuck on beam diverter step, and hence H1 Called me back.
After poking around and trying to recreate my steps last time this happened: alog 82192
I started reading the troubleshhoting guide for SQZ: https://cdswiki.ligo-wa.caltech.edu/wiki/Troubleshooting%20SQZ
I tried to request FDS_READY_IFO[50] and miss clicked [52] Which changed the alignment of the FC2 mirrors and ZM4. [Not any other ZM mirrors!]
Since then: I was able to narrow down the problem to the SQZ_FC not locking anymore. Likely because the ZM3 mirrors have now been moved.
OK, after returning FC2 and ZM4 back to their prior positions. I am now getting the Beam diverter error message again, which is where I started when the IFO called me the second time.
