Beamtest03 DAQ Control

This page will focus on the description of "user level" instructions in the Beamtest DAQ, although there are a number of expert-level controls that will not be described here.

The Beamtest DAQ is based on the CFEB_Control program.  This system uses X-Window menus with GUI controls for easy operation.  The following functions are to be performed by the users:

  • Configure the system
  • Under menu "Config---> Testbeam Config"  select  "Setup normal scint L1"

    {this operation takes about 1 minute to complete}

    A lot of configure information scrolls off the screen....this is normal.

  •  Initialize a run
  • Under Menu Config---> Testbeam Setup  select "New Run, same setup"

    {a green "Start" button will appear on the panel; this operation completes in a few seconds}

    A lot of configure information scrolls off the screen....this is normal.

  • Start a run
  • Press the green "Start" button ~5 seconds before the start of a spill

    {the green "Start" button changes to a red "Stop" button}

    A brief summary will be printed every 500th event.  Occasionally a condition will occur within an event that prints a lot of text on the screen...these indicate a problem with an event, but it is usually not critical, and normal operation will continue....this is normal.

  • Stop a run
  • Press the red "Stop" button when the desired goal is achieved, preferably between spills when the DAQ routine says

    "waiting for data."

    {the red "Stop" button disappears; this operation may take ~5 seconds}

    A brief "Run Summary" will appear on the screen at the end of the run.  Please note the Run Number, Number of Events, last L1A number and any non-zero status summary in the logbook.  Check that the data file is present:  look for the Run Number when you go into an Xterm and type

    ls -al /data/csc_data

  • to Start a New Run
  • See the "Initialize a run" section above and follow the instructions from there.
