The capability to rapidly and accurately detect and attribute nuclear materials is essential for any national strategy to combat and deter the use of nuclear or radiological weapons. Unfortunately, nondestructive detection and quantification of fissionable materials in challenging national security settings is difficult. This difficulty stems in part from the large phase space of potential xCfissionable material signatures and the lack of a single signature that will be effective in all scenarios. Hence the research team executed a basic research program to increase the basic knowledge of how to utilize fission signals from bremsstrahlung induced fission for the detection of fissionable materials. The research began by examining the time and energy spectra of delayed neutron and y-ray spectra in order to develop unique fission signatures.
