Many experiments tune the position of the beam on the camera with a slow full-frame image then, after tuning is complete, run fast 120Hz data acquisition in "full vertical binning" (FVB) mode.  To do this, we recommend that users use the IOC's "python viewer" for the full-frame viewing/tuning (without running the DAQ) then switch to FVB for 120Hz DAQ operation.

The steps below refer to two IOC panels.  Here are two screen shots of a working Andor.  The first image is the main panel, and the second image is a "detail" subpanel.  It is accessed from the lower box labelled "NewtonD0940P" on the middle-left of the main panel:

...

  • start the appropriate IOC panels (see below for command) on tmo-daq or rix-daq
  • end the DAQ run if one is in progress
  • click stop click "Stop" in the IOC window to stop the Andor (acquiring.  This is done in the "Image Collection" area in the middle-right of the main panel)
  • switch to full-frame (a.k.a. mode by setting "Readout Mode" to "Image" ) mode ( in the middle of the "detail" sub panel)
  • click start in the IOC window to start the Andor in full-frame (a.k.a. "image") mode.  ensure the triggering event-code and trigger width is mode.  ensure "Cam Trig Event Code" (middle right of main panel) and "Exposure Time" (top right of main panel) are set appropriately (typically event code 120 when beam is going to the soft X-ray line).  Setting exposure time too long will interfere with 120Hz operation.
  • open the "python viewer" at the top of the main panel
  • tune beam position on camera
  • when done tuning click "stopStop" in the "Image Collection" area in the middle-right of the main panel
  • in the middle of the "detail" subpanel set "Readout Mode" to "FVB" (full-vertical binning)
  • click start "Start" in the IOC window main panel middle-right to start the Andor acquiring in FVB mode
  • start a DAQ run
  • check for damage from the Andor in the DAQ-monitoring grafana window: psdaq#DAQMonitoring
