[dsg-svt] SVT work request: temperature/humidity sensor boards

[Yuri Gotra]

Hello Brian,

Yes, BOPS. If you are planning to modify the board, it would be helpful 
to make it smaller, if possible. We would need to stick the ambient 
sensors in the MVT. The length of the cables should be equal to the 
length of the SVT with all the support/mounting tubes plus the length to 
reach the patch panel. My estimate would be 5 meters. Since the patch 
panel screw-type connections will be replaced with boards with 
connectors, please account for these extra sensors and mount appropriate 
connectors on them.

We will have a very tight schedule this summer. MVT crew will do some 
studies when run is done (planned end date is May 7), then CVT will be 
moved to EEL and MVT will be set aside while we will work on modifying 
the SVT cooling system. All work should be complete by August (the next 
run will start on August 23rd).

Thank you
