SOLID STATE NEUTRON DETECTORS

Two methods of fabricating neutron detectors have "been developed utilizing the principles of the solid state ionized particle detector. The (n,a) reactions of Li and B are used for slow neutron detection. The Lithium and Boron are used as diffusants, for P and N type Silicon respectively, to create p-n junction diode detectors with efficiencies of the order of 1$>, 255 The fission of U is used for the detection of both slow and 255fast neutrons. The U is vacuum coated onto surface barrier detectors. Efficiencies of.O0h°jo have been obtained from thes
