(Corey, Mark, Slim, Zach)

With the Payload extraction from last week, and starting first thing this morning, we were able to empty HAM4 & HAM5, and remove a few more items from BSC2. Today's work occurred roughly from 8:15-11:30 (with a 20min break at 10am after the SEI stack was removed).  All photos for this work is located in Resource Space, here.  This signifies the last removal of an iLIGO HAM SEI from a chamber.  A breakdown of today's activity is below:

HAM4

Removed SEI system (kept Support Table in Chamber).  The Optics Table and Leg Elements were wrapped & bagged.

Note:  Zach found a loose 1/4-20 bolt inside the Optics Table.  This either dropped down there during Payload extract on Fri, or it has been along for a ride for the last few years (and Science Runs).

HAM5

Removed HAM5 Baffle (this will be scrapped for recycling)

BSC2 (& BSC1, BSC3)

Removed (4) Cornucopia Beam Dumps (black glass should be removed off of these guys, and rest tossed for recycling)

Removed (18) Side bolts from the Support Tubes (this is to prevent the need to have someone go into the chamber for BSC SEI extract later).

Removed forgotten allen wrench

Put H1 ITMx & ITMy Suspensions on their stops.
