[gautam, ericq]

Tonight's progress on ETMX:

  • All pickle pickers removed successfully, face magnet positions look symmetric (all on border of AR coating), side magnet same location as in yesterday's photo
  • Flipped around clamp blocks on winches and top blocks, refinished main clamp block not on tower yet
  • Trimmed viton tips of EQ stops, I had left them too long before, leading to bending and unwanted translation when in contact with optic
  • Inserted optic into bottom EQ stops, turned bolts to position optic at correct height and sort of pitch leveled
  • Threaded new length of wire up through both sides, clamped at winch. Made an effort to avoid any wire twisting. 
  • Winched until enough tension to sit in standoff groove, inserted second ruby standoff
  • Winched to just come up off of bottom EQ stops, observed neccesary correction of second standoff for rough pitch balance
  • Roughly pitch balanced by iterating standoff location
  • Partially inserted OSEMS, all four face magnets looked low. We figure it's more likely that our microscope was set to the wrong height, than all four OSEMS being too high by the same amount. (Given how the face magnets are all located on the concentric circle of the AR coating, we know there wasn't much translation error in the magnet gluing)
  • Did some common mode winching of both wire ends to get magnets to correct height, all OSEM alignments look good
  • Inserted OSEMs to half of open voltage
  • Having trouble engaging stable damping of all DoFs, this will be followed up in the daytime.

Since the air bake oven we had been using is out of commision, we're not sure where to do our EP30 test runs. If we are fortunate, we can get the fine pitch balance done tomorrow while Bob is still around, so he can help us quickly bake the test dots, so we can do the standoff gluing.
