Abstract :
A novel, simpler, competing technology was developed to detect X-ray quanta by a "direct conversion" process from X-ray to electrical charge. Although there are several photoconductor materials with promising characteristics, amorphous selenium has proven so far to have the most appealing combination of characteristics suitable for high resolution X-ray detection. The paper will introduce the basic operating principles of an innovative, amorphous selenium based, X-ray detector developed and manufactured by ANRAD Corporation, a Canadian wholly owned subsidiary of Analogic Corporation, Peabody, MA
