Yes as Patrick logged, the PISI was removed yesterday from BSC7--CoreyG JimW Zack Rodney Chris & HughR

We pulled the dome before lunch.  There was quite a bit a stuck O-Ring during the separation but we got it back in place without any unusual effort requiring maybe 20-30 minutes.  No issues after that--remember to PULL the draw string when installing a flat cover!

After lunch we went for the PISI pull.  The bolts below on the inside of the Support Tubes were generally bound and did not un-thread readily as they did in MidY.  The top bolts were fine.  Relief came with a little lift from the crane but we didn't fine tune that too much.  There are only 18 bolts below and James powered through.  Again, as at MidY, no trouble pulling the Support Table from between the Tubes.  We pulled the Work Platforms before we exited.

Except for flange/o-ring cleaning/inspection and Dome balancing, the Chamber is ready to be buttoned back up.

The Stack is now by the LEA roll-up door and we be de-stacked today.  Good location for a look-see of the simpler times of iLIGO.

I don't have any photos but Dale video'd and photo'd the entirety; I'm sure we'll see something good from him.
