WHAM4 ISI Damping Install Status

Did all the damping installs possible without making a chamber entry or moving SR2.

The north side Corner3 Broadband Blade and Flexure Dampers are installed.  The north side Corner1 horizontal and vertical GS13 can dampers are also installed.  On the south side, the Corner2 horizontal GS13 can damper is installed.  So 5 of 12 items complete.  The SR2 will have to be undogged and moved NW several mm to allow access to the top wall bolts. Chamber entry will be required on both the west and east sides for the remainder of damping installations.  With the final two blade spring access walls out and the broadband dampers in place, B&K hammering can be done to tune the TMDs.  Then all the walls can be remounted.  All remaining (and spare) damping material is wrapped up on the north side table in the cleanroom.
