(Chris, Corey, Jim, Rodney, & Zach)

In preparation for this week's BSC7 iLIGO BSC SEI extraction, the Dome & Door bolts were pulled out of BSC7 (except for four for each connection).

John asked to check the orientation of the BSC Dome once we have bolts out (there were issues with the O-ring when this Dome was last installed).  From the top and referencing bolt holes, the Dome is roughly rotated counter-clockwise.  A side note is that the outer diameters of both flanges on this connection must have not had high tolerances, because these diameters aren't very circular---i.e. sections of Dome flange overhung the Chamber flange in non-circular ways.

As with BSC8, the Scissors Tables for the chamber were set to their midpoints and Scissors Table Stop Links were installed to keep them there.

Jim's pair of fall-arrest plates were installed on the Clean Room.
