MidX Passive In Vacuum Seismic Isolation Extraction from BSC5
On Wednesday the BSC Dome was removed from BSC5 at the MidX station.  On Thursday the In-vacuum seismic isolation platform was removed and the Dome was replaced.
Elements of the passive stack still need to be separated and some elements preserved.  Further, one more in-vacuum operation is needed.  The Support Tubes need to be chocked in place and strapped down for transport.  This will require a few hours for a few people--let's say 3 & 3.  At that time the door can be replaced.
Currently the Dome bolts are all installed but not torqued.

Of Note:

*** The SUS feed thru on the Chamber now has a broken 4-40 screw body in one of the four threads. ***

As I'll likely be instrumental in installing the 25 additional feed thrus required for advanced LIGI on each chamber, I'm sure I'll remember this one.  And likely, the flange will have to be removed anyway as something other than the d-sub will be required in that location.
