FIELD-SHAPING MULTI-WELL AVALANCHE DETECTOR FOR DIRECT CONVERSION AMORPHOUS SELENIUM

摘要

A field shaping multi-well avalanche detector and method for fabrication thereof are disclosed. The field shaping multi-well avalanche detector provides stable avalanche multiplication gain in direct conversion amorphous selenium radiation detectors. The detector provides stable avalanche multiplication gain by eliminating field hot-spots using high- density avalanche wells with insulated wells and field-shaping within each well.
