SEMICONDUCTOR TYPE RADIATION DETECTOR

摘要

An apparatus for detecting radiation emanating from a source movable along a path has an elongated radiation-sensitive electronic semiconductor of a first crystalline phase. The semiconductor is positionable substantially parallel to the path. Inclusions of a second crystalline phase are contained in the semiconductor and have an electrical conductivity higher than the first phase. The inclusions are orientated substantially perpendicular to the current flow in the semiconductor response to the radiation. Two magnetic structures are disposed one behind the other laterally of the semiconductor along its longitudinal dimension and have respective magnetic fields which penetrate the semiconductor in mutually opposite directions.
