BSC10 - ETMY Headed towards closeout, again

This morning, Travis and I checked the ETMY suspension health and then made the pitch adjustments needed to compensate for the addition of the AMD devices to the front of the mass last week.  Like what was reported at LLO, roughly 200 uRad (up) of realignment was needed to recenter on the optical lever.  A few rounds of TFs showed that the suspension was still free of mechanical interferences, and OSEM speed dials looked good.

We then locked the test mass, swung the ACB back, attached the First Contact spray cone, and sprayed an application of the solution to the ETMY HR.  Per procedure, we removed the cone and reinforced the edge of the applied sheet with brush-on First Contact.  It now dries until tomorrow morning.  So, no oplev or pcal beams will be of use over night.

VE intends to work on the IP port near this chamber this afternoon.
