ABSTRACT:
A neutron detector array that includes a hollow member circumscribing an axis and bounding a volume. A divider extends parallel to the axis within the hollow member to divide the volume into a plurality of volume portions. A plurality of anodes extend parallel to the axis; at least one anode within each volume portion. A plurality of cathodes wherein the hollow member has an interior surface and the divider has surfaces that are coated with neutron sensitive material. Also, a neutron detector that includes a hollow cathode bounding a volume portion with at least a partial wedge cross-section, and an anode extending thought the volume portion. An electric field exists during operation of the neutron detector within the volume portion, the electric field varying across the cross-section, and the anode being located at an area of maximum field strength within the field. The detector may be used in the array.
