The current-monitor voltage used as a metric to adjust power was adjusted from 924mv to 914mv in a second attempt to quiet the glitching. OpLev damping is not being thus far on the ITMs and ETMs, however it is being considered for use in the not-so-distant future.
in other news...there is promise for the newest addition to the laser family being installed in the ITMX position by next Tuesday as it is passing stabilization testing in the LSB optics lab. Currently, the ITMX OpLev is a glitchy mess without a temperature stabilization enclosure (modified ice chest), the new standard of supply power, or armored fiber.
I checked spectrograms this morning after the power adjustment i made yesterday. Since the swap on 12/4/2018 there was a large improvement which was made better by the first adjustment on the 18th. Since then I made two adjustments. It seems that the glitchiness isn't any better than it was prior to the adjustment made on the 18th. I returned the power level back to what it was on the 18th and deduce that it "is what it is" until it can be replaced. ITMX is 1st priority and as it stands, ETMY is 2nd.
