Technique and apparatus for Pulsed OSL Readout of YAP:Mn Dosimetric Detectors with Enhanced Dynamic Range

The experimental technique to study the dosimetric response of Mn
²⁺
-doped yttrium-aluminum perovskite (YAP:Mn) by means of optically stimulated luminescence (OSL) readout in pulse mode has been developed. A method of synchronous background subtraction has been adopted to extend the lower end of the dynamic range of light flux. A dedicated apparatus has been designed implementing this technique with application specific optical layout, photometric subsystem and the measurement procedure. Some experimental results are presented to demonstrate its features and capabilities for ionizing radiation dosimetry applications.
