After several lock losses of DRMI that were obviously caused by DRMI WFS running away with the optics, we've begun the arduous journey of going through each step of the DRMI WFS turn on process. We're trying the usual -- identify which step is problematic, slow things down, try turning on with low gains and no boosts, etc. We've run through tuning dark offsets suspecting we might have problems there and our earlier experience with the TransMon QPDs, but they didn't change too much. We've checked whitening filters and gains, all looks OK.

Jenne's gunna stick it out with Bartlett for a few more attempts of finagling the WFS loops in hopes of working through them enough that they offload goodness to the SUS, but TJ and I are going to call it a night.
