WidePIX (L) MPX3 with 55 um pixel pitch

Available OPERATION MODES of the WidePIX (L) MPX3 devices with 55 um pixel pitch and their functionality:

  • SPM 1 CH (Single Pixel Mode – one channel)
    One counter is in use. One energy threshold (energy channel) is available. Measurement output: one 12-bit or 24-bit image representing the number of events per pixel.

  • SPM 2 CH (Single Pixel Mode – two channels)
    Two counters are in use. Two energy thresholds (energy channels) are available. Measurement output: two 12-bit images representing the number of events per pixel.

  • CSM (Charge Summing Mode)
    Two energy thresholds are in use. Measurement output: one 12-bit or 24-bit image representing the number of events per pixel.

Note: After changing the operation mode, values of the energy thresholds may change according to the respective energy calibration.

All modes can be moreover operated in several RANGES (Gain modes):

  • Broad – the largest threshold range.
  • Narrow – better energy resolution at lower energies.
  • Super Narrow – very limited threshold range, the best energy resolution at lower energies, better signal-to-noise ratio.
    Note: Super Narrow range is not available with silicon detectors.
