X-Ray Energy Resolution Calculator

There are many parameters to consider to ensure that the theoretical energy resolution is realized with a direct detection CCD camera. A few of the most important parameters that deliver the highest energy resolution are, type of CCD used, best Charge Transfer Efficiency (CTE), lowest thermal noise, and linear response for the full dynamic range.

  • First select the X-ray detector
  • Move cursor over plot area or Enter the X-ray Energy
  • Select CCD readout speed
