FAQ and common problems and solutions

  • If you want help installing CODA and the relevant environment software on a local machine, contact Bryan Moffit.
    • The CODA (2.6.2 - relevant to Prex DAQ) software is documented and has an installation guide on the CODA Website.
    • Chandan Ghosh will write a full installation process documentation guide for the Stony Brook group's ELOG which will also be available here.
  • Installing an NFS file server on a machine (for use in serving Centos OS and CODA files for installation and booting).
  • Hall A Counting House Helicity Control Board User's Guide.

Goals for PrexII running

  • Work on the Parity DAQ to bring the Trigger Supervisor (TS) into its proper overseer role
    • ✓ This requires shifting from COMPTON to ADAQ3 computer and verifying all connections and .crl files behave as expected (completed in 5-23-2018 meeting)
    • ✓ Set up Trigger Supervisor DAQ to communicate correctly with Injector DAQ from ADAQ3 computer
    • ✓ Set up Counting Room DAQ and add to TS (should be easy)
    • ✓ Set up RHRS DAQ and add to TS (completed in 5-24-2018 meeting)
    • ✓ Set up LHRS DAQ (completed in 5-25-2018 meeting) with new QWeak ADCs, connect it to RHRS, and add to TS (completed in 5-31-2018 meeting)
  • We want an automated system that will vastly simplify the life of WACs (Fall 2018) - see June 1 2018 afternoon meeting for more
    • It should read information from CODA, EPICS, and shift operator schedules as runs start and stop
    • It should make standard analysis plots
    • And it should display these diagnostic and physics results on a collaboration viewable webpage
    • This will likely involve mimicking the existing ELOG automated systems
  • We should rewrite the existing PAN (Parity ANalyzer) into JAPAN (Just Another Parity ANalyzer)
    • This is partly to update the codebase to incorporate the QWeak analysis updates
    • And also to build expertise and familiarity in the current collaboration
    • JAPAN is currently in development at www.github.com/JeffersonLab/Japan
