BSC6 EndY Support Tubes Jigged & Set
Dome is back on--Jimw GregG Scott Slim MarkD Hugh

We dropped the iLIGO Support Table into the chamber and it landed (in a very controlled way) onto the Support Tubes.  We bolted the Table to the Tubes to fix the Support Tubes' relative position.  We balanced the position of the Support Tubes wrt the Chamber and then secured them to the Crossbeam via the V-Blocks.  We then disconnected the Table from the Tubes and pulled it from the Chamber.  It was a little trapped between the Support Tubes suggesting we hadn't been as iterative in the torquing of the V-Blocks to the Crossbeam as we should have been.  We tweaked the a V-Block outward and the Table slipped out.

We wrapped up the day by replacing the Dome and the East Door Cover after we emptied the chamber of our detritus.

Some photo of the day: 1) The Jib Cranes holding the Support Tubes-there is one of these at each of the four corners.  2) The Support Table flying toward the Chamber.  3) The Support Table bolted to the Support Tubes.  4) GG hoping to not be forgotten!

Thanks Crew, good job!

The Support Tubes were set horizontally wrt the Chamber D nozzles to < +- 1/16", maybe closer to +-1/32.
