SQZ Team. Last night we left the ADF on at 1300Hz while the IFO thermalized. See attached plot for how ADF calculated phase changes 25degrees over the first 5 hours of the IFO lock. We plan to repeat this tonight with the ADF nearer 100Hz (where H1 range is effected by SQZ changes more) and expect less change. See alog 69055 for optimizing SQZ angle during first ~1hour of lock. SQZ angle H1:SQZ-CLF_REFL_RF6_PHASE_PHASEDEG = 140.33 throughout.
Nutsinee left the ADF at 90Hz last night (alog69127) and I've attached the 90Hz thermalization plot. At 90Hz SQZ changes <5 degrees within the first hour so is much more stable than the high frequency squeezing.
I'm unsure what is happening in the first ~10 minutes of NLN when both frequencies change +/-10degrees.
