HAM5 Closeout Status COB

Betsy, Travis, Hugh

So, turns out we couldn't get the doors on HAM5 by COB because everything took longer than expected today (cable entry below) and everyone has already put in ~6 days of work this week.  However, we completed the entire list up to actualy putting the doors back on.

 

Things we did to enable doors going on first thing Monday morning were:

SR3

Pulled F.C. from HR surface, blew N2 for ~ a full min.

Unlocked optic.

Recenter some M1 flags - after 20 mins of knocking the optic around we decided they were good enough because we didn't want to risk breaking a magnet off or compromising cables again this late in the game.

Recentered M3 stage AOSEMs.

Fought with DTT and the suspension to eventually get quick TFs in all 6 DOFs at top stage - L has low coherence after 0.7 which doesn't look great, but below that where all of the peaks are, things line up nicely - PASS

SRM

Pulled F.C. from HR and AR surface, blew for ~30 sec on each.

Unlocked optic.

Took quick TFs of 6 DOFs - all look good - PASS

OSEM centerings are good.

 

Executed Exit Chamber procedure for tool sweeps, cleaning, 3" horizontal wafer placement, 1" witness optic FC removal, subsystem signoffs, etc.

Hugh unlocked ISI.

Jim will take the opportunity to run measurements on HAM5 ISI tonight.

BUBBA - YOU ARE A GO FOR DOOR INSTALL ASAP MONDAY MORNING.  I will follow up on text, and let you know if any status changes.
