Abstract: In this study, the temporal response of a planar
Cd1-xZnxTe sample at each frequency of a scanning
square-wave test pattern, has been measured. The experimental setup offers
potential capabilities for feasibility studies, research, and evaluation of the
temporal response and noise characteristics of a
Cd1-xZnxTe X-ray sensor system, for fast digital
radiographic applications. The dependence of the temporal response of the
experimental X-ray detector system on physical and geometrical parameters has
been determined experimentally. The results of this study indicate that the
overall temporal response of the Cd1-xZnxTe detector
system improves with increasing applied electric field, and scanning speed, as
well as decreasing detector thickness, and object magnification. Further
improvements of the geometrical and signal collection parameters of the
detector will improve the speed of the X-ray system significantly.
