Geometrically optimized fast neutron detector

Abstract From the Canadian patent

An improved fast neutron detector fabricated with alternating layers of hydrogenous, optically transparent, non scintillating material and scintillating material. Fast neutrons interact with the hydrogenous material generating recoil protons. The, recoil protons enter the scintillating material resulting in scintillations. The detector is, optically coupled to a photomultiplier tube which generates electrical pulses proportional, in amplitude to the intensity of the scintillations and therefore are an , indication of the energy of the fast neutrons impinging upon the detector. Alternating layers of materials, are dimensioned to optimize total efficiency of the detector or to optimize , …
