  • Three-axis asymmetric radiation detector system
    Patent number: 6100533
    Abstract: A three-axis radiation detection system whose inner and outer electrodes are shaped and positioned so that the shortest path between any point on the inner electrode and the outer electrode is a different length whereby the rise time of a pulse derived from a detected radiation event can uniquely define the azimuthal and radial position of that event, and the outer electrode is divided into a plurality of segments in the longitudinal axial direction for locating the axial location of a radiation detection event occurring in the diode.
    Type: Grant

  • Segmented electrode radiation detector
    Patent number: 5757007
    Abstract: The segmented electrode radiation detector includes a semiconductor diode; an internal recess having a decreasing cross-sectional area extending at least partially axially into the diode. The plurality of inner electrode segments disposed axially spaced from each other on the surface of the recess and electrically isolated from each other for defining a plurality of axially discrete detection zones.
