Abstract
A high-efficiency apparatus for detecting fast neutrons includes an assembly of disks of solid state charged particle detector material, or other appropriate charged particle detecting devices, disposed between adjacent thick (on the order of 1 mm) disks of fissionable material. The fissionable material must be an isotope that has a sharp increase in the neutron-induced fission cross section at a neutron energy of about 100 keV or greater, i.e., a fast neutron. An array of such assemblies housed in a thermal neutron shielding structure provides a threshold detector for fast neutrons resulting from neutron-induced fission of the fissionable material.
