Claim:
1. A neutron detector module, comprising: a container; a distribution of proportional counters positioned in a defined array in said container, each of the proportional counters including a supply of a neutron sensitive gas for reacting with neutrons, said reacting generating ionizing reaction products, and wherein the proportional counters include a multitude of tubes, each of the tubes having a diameter between 0.50 inch and 1.00 inch; and a multitude of electrical conductors, each of the conductors extending into one of the proportional counters, wherein said ionizing reaction products generate electric current pulses in the electrical conductors; and wherein: in said defined array, the proportional counters are positioned in a plurality of parallel rows; centers of the parallel rows are spaced apart between about 0.834 and 1.0 inch; and within each of the rows, centers of the proportional counters are spaced apart between about 0.896 and 1.063 inches.
