    • 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.
    • 一种中子探测器阵列,包括一个围绕轴线并限制一个体积的空心构件。 分隔件在中空构件内平行于轴线延伸,以将体积分成多个体积部分。 多个阳极平行于轴延伸; 每个体积部分内的至少一个阳极。 多个阴极,其中中空构件具有内表面,并且分隔件具有涂覆有中子敏感材料的表面。 而且,中子探测器包括具有至少部分楔形横截面的体积部分的空心阴极和考虑到体积部分延伸的阳极。 在体积部分内的中子检测器的操作期间存在电场,电场横截面变化,并且阳极位于场内的最大场强的区域。 检测器可以用在阵列中。
