This paper reports on a recently developed neutron diagnostic probe system that has the potential to satisfy a significant number of van-mobile and fixed-portal requirements for nondestructive verification of sealed munitions. The probe is based on a unique associated-particle sealed-tube neutron generator (APSTNG) that interrogates a TLI (treaty-limited item) with a low intensity beam of 14-MeV neutrons generated form the deuterium-tritium reaction and that detects the alpha-particle associated with each neutron. Gamma-ray spectra of resulting neutron inelastic scattering and fission reactions identify nuclides associated with all major chemicals in chemical warfare agents, explosives, and drugs, as well as many pollutants and fissile and fertile special nuclear material. Flight times determined form detection times of the gamma-rays and alpha-particles yield a separate tomographic image of each.
