[Dsg-hallc_nps] Can you consult on a HV control problem ?

[Robert Michaels]

Ralph Marinaro and a small team fixed this in hall A.  Here is their log entry
https://logbooks.jlab.org/entry/4113839

Largely what's happened here is that the CAEN HV units are fairly new to hall A
(we had LeCroy before), and Steve Wood implemented an EPICS controls, but then
retired.  Steve did leave a legacy of Wiki instructions.  And I asked Ralph to review
possible improvements to that Wiki.  I know that the DSG group has experience
with these HV crates -- I believe its the same kind as NPS has -- so that's why
I reached out.  But then Ralph and his team were quick to fix things.

I'd be interested to know how they fixed the problem.
And what kind of HV crates they're trying to communicate with.

It looks like the experimenters fixed their problems.   So, there's no urgency now.
I've asked them to document the experience in the HALOG logbook.

Sincerely, Bob

We're using the CAEN mainframes in Hall A.  Steve Wood set up a lot of the
EPICS, I think they use CS Studio.  Now, some hall A workers are having trouble.
See the logbook below.  Are you able to consult on this ?  It might be something
simple, but sadly we are ignorant, or at least I am.

Contact me (757 782 7042) and I'll put you in contact with someone on
the experiment if you can help.
