3. Experiment Parameters

Experiment information requires 4 fields to uniquely identify a detector image:

  • Experiment Name: Experiment name, (e.g. cxi06216)
  • Run Number: Run number, (e.g. 22)
  • Detector ID: The full name (e.g. CxiDs1.0:Cspad.0) or DAQ alias (e.g. DscCsPad) for the detector. Available area detector names are printed to Terminal when Experiment Name and Run Number are entered.
  • Event Number: Event number starting from 0. Seconds, nanoseconds, fiducials and total number of events are read-only.

Display 

  • Logscale: Display detector image in logn scale.
  • Image Properties: There are many image properties besides pixel readout values that can be displayed.
    • gain corrected ADU: Pixel values after pedestal, common mode, and gain correction. (Default display)
    • common mode corrected ADU: Pixel values after pedestal and common mode correction.
    • pedestal corrected ADU: Pixel values after pedestal correction.
    • raw ADU: Pixel values without any correction.
    • photon counts: This feature isn't implemented yet.
    • gain: Gain correction values. Pixel values are calibrated by multiplying by the gain.
    • common mode: Common mode correction values. Pixel values are calibrated by subtracting the common mode.
    • pedestal: Pedestal correction values. Pixel values are calibrated by subtracting the pedestal.
    • pixel_status: Status of each pixel determined from a dark run. Good pixel status is zero. Calibrated pixels that have bad pixel status are set to zero.
    • pixel_rms: Root mean square of pixel values from a dark run.
    • quad number: Corresponding detector quadrant of the pixel (Quad,Seg,Row,Col)
    • seg number: Corresponding detector segment of the pixel (Quad,Seg,Row,Col)
    • row number: Corresponding detector row of the pixel (Quad,Seg,Row,Col)
    • col number: Corresponding detector column of the pixel (Quad,Seg,Row,Col)
    • coord_x: Pixel x-coordinates
    • coord_y: Pixel y-coordinates
  • ADU threshold: Threshold used for display purposes only (Default: -100 ADUs)
  • Common mode (override):
    • Apply common mode (override): Turn on/off common mode ignoring the values deployed in /reg/d/psdm/<instrument>/<experiment>/calib directory.
    • parameter 0, 1, 2, 3: Parameters are described here --> Common mode correction algorithms. Optimized common mode parameters can be deployed using Calibman, e.g. (3, 1000, 1000, 128) or (5, 50, 0, 0)
