Abstract :
The rising and falling edges of detected signal pulses have been measured utilizing X-ray ionization of a planar Cd1-xZnx Te system under different irradiation geometries, at different detector thicknesses, and applied electric fields. The experimental results of this study indicate that the time response of the CdZnTe based X-ray system is suitable for digital pulsed radiographic applications
