HAM3 Dial Indicators & In-Vac Cabling (a first start)

(corey, jim)

Dial Indicator Install (this work was on Tues)

Dial Indicators used to monitor the HAM3 ISI/HEPI system are roughly in place.  This hardware should not be touched/bumped as it will be used to monitor and ultimately help position the HAM3 ISI. 

Cabling (this work started Wed)

In-Vac Cabling for HAM3ISI is mapped out according to D1002874.  Since Septum work finished up this afternoon, I started running Corner-1 cables to their feed through.  I was able to get all cables to the feedthrough (but opting NOT to screw down to feed-thru), EXCEPT for the H1 Actuator (it's 70" long cable was a foot or so too short!).  At any rate, I only ran cables for Corner-1.  I went to the other side of the chamber and separated Corner-3 cables from Corner-2 (since they're going to opposite sides of the Chamber).  Corner-3 looks like it will be the tough one to work on (due to feed-thru in middle of Chamber).

I labeled the dirty side of feedthroughs.
