After ~3 days of ground loop hunting, fixing, breaking, fixing as well as a relocking of the ISI, we finally are getting good results on the 18 DOF transfer functions for all 3 suspended chains in BSC10 (ETMY main, ETMY reaction, and TMS).
Attached are results of the TMS. Peaks from today overlap peaks from previous closeout sessions.
Kissel has cast an eye on these and calls them good.
Will post the ETM set shortly.
Next up: First contact and electrometer optic readings, chamber clean-out, then closeup!
Also, attached is the latest set of ETMY and TMSY spectra after all of the ground loop work. Combs are gone.
Attached are the ETMY M0 and R0 chain transfer functions taken yesterday. The 2.5Hz noise is showing itself again on the Transverse DOF TFs just a bit - maybe related to the ISI being locked again. No knobs to turn for it so we're going with it for now.
