This morning after Fil switched ON the ESD HV on EX (EY was already ON), I took the OPLEV charge measurements on ETMX and ETMY. I will post the results after processing the data.
Both the suspensions were restored after the measurements were complete.
Also, I noticed that on ETMX the amplitude of L3 calibration lines was set to zero since Jan 16, 2024 (when last measurements were taken), I have set it to the nominal value of 0.12 after trending it.
I ran the analysis this morning for the OPLEV charge measurements that Rahul took on Tuesday.
For ETMX, the charge is trending down towards zero on all DOF & Quads!
For ETMY, the charge appears to be mostly stable around zero with some small uptrends on LL & UL and only on LL (P&Y) the charge is just above 50[V].
