STATE of H1: Observing at 161Mpc
OUTGOING OPERATOR: Oli
CURRENT ENVIRONMENT:
SEI_ENV state: CALM
Wind: 4mph Gusts, 1mph 3min avg
Primary useism: 0.03 μm/s
Secondary useism: 0.43 μm/s
QUICK SUMMARY:
H1 has been locked for 1 hour.
All systems running well.
Lockloss potentially Caused by PSL issues
The first Channels that show motion is the H1:PSL-FSS_FAST_MON_OUT_DQ
Relocking now, Currently @ Engage soft loops.
Trends on this lockloss are coincident with PSL FSS / ISS / TPD glitches - so I think the PSL tag is appropriate here.
We added MC2_TRANS to the scope (top right subplot), and it shows power changes earlier than IMC_TRANS_{IN1_OUT}_DQ channels.
I think this means that IMC power changes do happen within 1 ms of FSS glitches starting, which wasn't clear from the IMC_TRANS channel we've been using (where the 16k IN1_DQ and 2k OUT_DQ channels both showed >ms delays of IMC power changing).
