Abstract
Sodium iodide doped with thallium is the lowest cost crystalline scintillator material available in large sizes. A PC-based scanning system consisting of two independently programmable x-y translators is used to characterize the response of large area (60 cm X 90 cm) X-ray detector plates by measuring the response amplitude and energy resolution generated by X-ray energy excitation. A variety of energy sources and scanning of the source are employed in addition to scanning of the photomultiplier photon detector. Initial scan data and analysis from a 40 cm X 40 cm detector plate are presented.
