TJ and I turned up the CO2s from 1.7W to 2.0W today before we lost lock for Tuesday Maintenance at 2024/09/10 15:10 UTC. We then lost lock at 2024/09/10 15:18 UTC. We did this after mention that PRCL to CHARD coupling could be reduced by CO2 power changed in 79989, but we didn't have time to think about if we should make an injection.
Checked when we turned the CO2s up for 7 minutes, that this had no noticeable effect on squeezing level or sqz alignment, plot attached. But maybe 7 minutes isn't long enough to see any changes, we could try again with more time or try turning the CO2s off before Tuesday Maintenance
Checking as LLO sees the Squeezing and SQZ alignment/mode matching may be related to changes in CO2 power (or alignment), see 72244.
