HAM3 doors on

Jeff B, Andreas, Jeff K, Stuart A, Jeremy B, Matt H, Apollo).

Both doors on HAM3. Jeff B started by inserting optic Started on PR2 side as that is the "least" important of the two optics in tha chamber. There was a drop of FC under the optic (not from a run down the optic, obviously fell off during painting) so that was cleaned up easily. Once particle counts deemed good to go, first contact was peeled (there was a little bit of the outer crust left behind from say 2-3 o'clock position and 4-5 o'clock position.....I decided not to attack it with a swab and just leave it...Calu you need to practice your first contact outer layer painting skills :-) :-D). Its only a bit and well out of the beam path. Optic was unlocked and TF's taken. Once given the all clear door went on. Stuart has a log of particle countsduring process, timeline and also how many particles I deemed I saw on optic throughout the process.

Once HAM3 east door on, we checked particle counts on west side. These were low and so went to peel FC here. Found that top gun nitrogen tank low, so swapped out before blowing to peel FC. Once swapped, peeled FC, again unlocked suspension and then did TF's. Once these past door went back on. They had some troubles getting a good angle to put door on so took a little longer than wanted. Again Stuart has log of timeline, particle counts, particulates on optic, etc.

I talked to Travis about mobility wafer and if he wanted it replaced (by replace I mean swap out the the wafer already in it....it was put back in its original position before the ISI guys balanced the table by Travis and I) before we closed up. He suggested to leave it as looking for a delta if anything moves from time of closing/pumping down...so I left it as is.

Damn...I know one thing I forgot.....to peel the FC on the small optic...how did I forget that #facepalm.......hmm  I wonder if I took off a viewport I can reach in and get it. Its on the outer leg of the MC2 suspension. Will talk to Calum about.  Who has the longest reach at LHO ? We may just be able to get it from the viewport.....To all and sundry....dont let me forget for HAM2............

Attached below is a log and particle counts taken during the HAM3 work covering the period 1300 to 1515 (local).
