Advice from Dan Damiani on running the Newton Camera:

  • TMO: run Dan's IOC panels on tmo-console using this command: /cds/group/pcds/epics/ioc/common/andorCam/R0.4.0/children/build/iocBoot/ioc-tmo-andor1/edm-ioc-tmo-andor1.cmd
  • RIX: run Dan's IOC panels using this command: /cds/group/pcds/epics/ioc/common/andorCam/R0.4.0/children/build/iocBoot/ioc-rix-dir-andor/edm-ioc-rix-dir-andor.cmd
  • Camera "Software Development Kit" (SDK) manual can be found here: Andor CCD
  • Do not set the exposure time to 5 ms: 2ms is the max exposure time for 120 hz, it takes 5+ ms for the readout so you are dropping every other event (with autocorrect at 120Hz).  A too-large setting will be seen in the main IOC panel with the "sync status" oscillating between locked/unlocked.
  • Also they have the evr delay set to zero, but with a large enough window that might be okay
    • Looks like the last time they ran the VLS at SXR the evr delay was 0.00085 s and the width was 1e-5 seconds
  • The IOC shutter settings do not matter: they are only to control an external shutter (which we don't have in TMO)
  • you can also try to experiment with toggling TMO:VLS:CAM:01:AndorKeepClean to see what effect that has (use Stop-Acquire before changing this setting).  use the pvget/pvput commands to modify the value.
  • use the "python viewer" at the top of the IOC screen to view images.  the edm viewer is broken.
  • we recommend tuning the full-frame image without running the DAQ using the python-viewer, then putting the camera into Full Vertical Binning (FVB) mode using the IOC window for 120Hz line-out running
  • the event code set in the IOC window should match the event code used in the DAQ readout group (in the "timing" system configuration).
  • ioc "autosave" files can be found here: /cds/data/iocData/ioc-tmo-andor1/autosave/. (you can look at the various autoSettings.sav* files)

  • As far as I can tell there are only a few PVs that actually matter for the temp:
    TMO:VLS:CAM:01:Temperature_RBV # readback of the actual setpoint temp. I am not sure this one works
    TMO:VLS:CAM:01:Temperature # get/put the temperature setpoint (edited) 

    # turn on/off the cooling
    TMO:VLS:CAM:01:AndorCooler
    # readback the on/off state
    TMO:VLS:CAM:01:AndorCooler_RBV
    # string "status" message about the cooling state
    TMO:VLS:CAM:01:AndorTempStatus_RBV
  • TMO:VLS:CAM:01:TemperatureActual is supposedly the temperature readback
