TMS Alignment Work

Our first alignment check by Doug showed that we were low ~1cm & to the right ~1cm (when looking from the front).  Since vertical adjustment is fairly easy, we went about correcting some of this vertical by re-hanging the TMS. 

The wires coming down from the Upper Structure have three vertical position holes to connect to; they are 6mm apart from each other vertically.  When we hung the Lower Structure last week, we could not recall which set of holes we used when we were in BSC6 so we screwed our clamps into the "middle" set of holes.  So, with us being low by 1cm we needed to attach the wires to the lowest set of holes and get everything to move up 6mm.  This requires using the Genie lift to come in and take the load of the TMS Lower Structure so we can disconnect the wires & re-connect to lower holes to raise the entire assembly.  This vertical move did the trick and we were right on the scribe = VERTICAL is GOOD.

Took another look at horizontal after the vertical change and for horizontal, we need to move the entire assembly 6.5mm to the "left".  Since this is a major endeavor, we're going to tackle this tomrrow with Doug.  We'll need to get Pushers & teflon-tipped dog clamps on deck.

Mirror Mount Dump Clips Installed

After a second iteration of modifying in the machine shop, these clips were finally able to slip on to the mirror mounts (these are so much more easier to install before optics are installed!).  We now have (8) of these Dump Clips installed on mirror mounts.

BOSEMs working & TMS Damped

We were not able to look at our TMS SUS signals last week.  Turns out the cable was not connected at the sattelite box/rack.  Once we were connected, we adjusted BOSEM positions to get their outputs zeroed.  Once the BOSEMs were positioned, the TMS was also damped (but the IOP Watchdog tripped quite a bit).
