Abstract:
1. A method of making a neutron detector comprising the steps of: a) forming a first conductive cathode sheet; b) depositing a neutron-reactive coating onto a selected area of said first cathode sheet, said coating comprising an inorganic material containing an isotope selected from the group consisting of: boron-10 and lithium-6; c) attaching a first dielectric sheet to the coated surface of said first cathode sheet, said dielectric sheet having openings therein so that said dielectric sheet covers no more than about 80% of the area of said first cathode sheet; d) attaching a plurality of anode wires to said first dielectric sheet, said anode wires disposed generally parallel to the surface of said first cathode sheet and separated therefrom by said first dielectric sheet; e) attaching a second dielectric sheet of similar shape to said first dielectric sheet on top of said anode wires; f) forming a second cathode sheet; g) depositing a neutron-reactive coating onto a selected area of said second cathode sheet; h) attaching a second cathode sheet to said second dielectric sheet so that a cavity is formed, having said anode wires and said neutron-reactive coatings contained therein, and, i) placing an ionizable gas in the space adjacent to said cathode sheets and surrounding said anode wires.
