Table/Telescope Not Installed (Ready To Go)...Continued Cabling Work

The Continued Story of CB3

On Wed, there were unresolved issues with cabling for the TMS.  The main issue was a cable bracket (CB3) which, on a drawing, is supposed to be on the east side of the table (i.e. -Y side of TMS), but having it here has limited access, and it would be even worse after we box it in when the Table/Telescope was installed.  

Now the cables (TMS OSEMs) which use CB3 eventually run to a feedthru which is quite on the other side of the TMS (i.e. the +Y side of it); on this side of the TMS there is lots of open space & getting to the feedthru is trivial.  So, after consulting with Cheryl/Mike/Calum, Jeff & I decided to move CB3 from it's "called out" location on the "edge" of the table to roughly the center of the table.  So, the "quadrapuss" OSEM cable D1000234 was run to this feedthru (and excess bundled near bracket), then D1000225 was run straight "north" on the table and out to a spot where Jim W suggested---then he'd be able to dress it on the ISI and on to the feedthru.  The beauty of this cable run is that we have elegant access to the cables & cable bracket.

This leaves us ready at the Cartridge to bring in the Table/Telescope.  

Table/Telescope Installed On Test Stand:  Promise!

Throughout the day, I also prepped the Table/Telescope for the trip form the TMS Lab to the Test Stand.  I blew off the Telescope Mirrors, installed the TMS Cover (to protect Table optics), and arranged the Genie and Table/Telescope for the move first thing tomorrow morning.

Attached are photos of how Jeff B. ran the cabling and where he positioned CB3 (the D1000225 has about 14' of cable and it is coiled on the table ready to be grabbed by SEI for final dressing to feedthru).
