Image plate characterization and absolute calibration to low kilo-electron-volt electrons.

Area of Science:

• Physics
• Materials Science
• Instrumentation

Background:

• Image plates are widely used for detecting charged particles in various scientific fields.
• Accurate calibration of image plates to electrons is crucial for quantitative measurements.
• Existing calibration data for electron detection can be inconsistent across different studies.

Purpose of the Study:

• To perform an absolute calibration of an Agfa MD4.0 image plate to electrons.
• To determine the sensitivity of the image plate in the low keV energy range (1-30 keV).
• To compare the obtained calibration data with previously published results.

Main Methods:

• Utilized an Agfa MD4.0 image plate without a protective layer.
• Employed a Fuji FLA7000 scanner for image plate readout.
• Performed absolute calibration using a well-defined electron beam in the 1-30 keV range.

Main Results:

• Established absolute calibration data for the Agfa MD4.0 image plate to electrons.
• The sensitivity of the image plate was characterized in the 1-30 keV electron energy range.
• Calibration data showed consistency with other published findings.

Conclusions:

• The characterization provides reliable absolute calibration data for image plate detectors.
• The obtained calibration is suggested to be valid for electron energies up to 100 keV.
• This work contributes to accurate electron detection and quantification using image plates.
