[Dsg-hallc_nps] [EXTERNAL] Re: NPS/DSG update

[Brad Sawatzky]

Hi folks,

Aaron and I had a brief email exchange earlier in the week, but I also
had some more general follow-up questions to the DSG group.  The NPS
Collaboration is getting to the point where the controls noted below
will be required, even after all of the delays associated with the PMT
noise issue.

We will need working software within a few weeks to continue the
program.  I understand that things are being worked on, but I'd like
a rough, but meaningful, timetable for the development work noted below
to help us plan on our end.

o Phoebus HV GUI isn't quite ready to go.
  - The Instructions here aren't enough to run the GUI
      https://wiki.jlab.org/cuawiki/index.php/NPS_Controls#Phoebus_HV_controls
  - I presume that works from the cdsg account, but that is not the
    account that we will use.
    - Can you add instructions on how to install a copy of that software
      in a different account (provide a tarball, etc.)

o Chiller controls: Please add documentation to the wiki on how to
    configure and run the relevant software
    https://wiki.jlab.org/cuawiki/index.php/NPS_Controls#Chiller

o Thermal Readbacks: Please add documentation to the wiki on how to
    configure and run the relevant software
    https://wiki.jlab.org/cuawiki/index.php/NPS_Controls#Thermal_Readbacks_.28Keysight.29

o Can you provide an ETA on the LV controls software?
  - I had understood there was a GUI for the same Weiner MPOD system
    running in Hall A associated with the GEMs.  Can that be adapated?

o Can you provide a status update on the LED controls
  - Do you have a testbed established using the boards and drivers you
    in your possession?
  - Have you been able to take to the boards with the low level code
    Bryan Moffit, William Gu, et al have provided?

All the best,
-- Brad
