[Dsg-halla_gem] [EXTERNAL] SBS gas distribution rack moved to EEL/125; help setting up?

[George Jacobs]

There was a blue metal bin on rails with the rack when it was in rm125 previously that contained the hardware for the rack. Could this bin of rack parts be brought back to EEL rm 125?

Hi Marc, et al,

The SBS GEM gas distribution rack was recently moved to EEL/125.
That is where the SBS GEM layers are being stored and worked on.

Marc, can your group support the GEM group in completing the setup
of that gas system so they can start flowing gas to the layers in
EEL/125?  It will need to be reconnected to the network, some gas line
'jumpers' need to be run between the two sides of the rack, and lines
need to be run from the rack to the GEM modules themselves.  (I believe
Jack fixed the issue with i2c multiplexing in that rack.)

I also moved a large spool of 1/4" poly into EEL/125 so fresh gas lines
can be run.  General consensus is to position the rack in the most
convenient location in EEL/125 and run (relatively short) gas lines of
the needed length to the individual GEM modules.  We will cut a set of
new (longer) gas lines for the final setup in the Hall in a couple
months.

I'll be out of town for about a week, but I've discussed this with John
Boyd and Anuruddha, and they are generally in either EEL/125 or /126.
