[Dsg-hallc_controls] SHV Adapter for CAEN A7030TN HV Module

[Brad Sawatzky]

Hi Marc,

I know I'm a week late on this -- sorry.  Last couple weeks have been
super busy and this got lost in my inbox...

Thanks very much for following up on hardware for the testing, and the
good catch on the potential fabrication issue with the pins.

Let's have a brief chat about the HV plans on during/after the Hall A
gas distribution meeting on Monday.  I can give you a more information
about what our plans are for the A7030TN cards/crate(s).  Any support
DSG can provide to pull the needed parts/cabling together would
definitely be appreciated -- we do have some time for that (1+ years),
so it's not a rush job.

I found the req for the test chassis parts and signed them just now.

All the best,
-- Brad
