Pulse Train Analysis Applied to the Re-Evaluation of Deadtime Correction Factors for Correlated Neutron Counting
… used at nuclear fuel cycle facilities for the non-destructive assay (NDA) of plutonium (Pu). Correlated event rates are used to quantify mass values of spontaneously fissile nuclides and derive total Pu mass. These methods are limited in accuracy by uncertainty in the deadtime correction. A …

Neutron Resonance Transmission Analysis of Nuclear Material Using a Portable D-T Neutron Generator
… material is important for nuclear security, nonproliferation, and safeguards missions. Existing techniques have limitations in terms of their isotopic specificity, isotopic range, and their capacity to analyze thick or shielded targets. Neutron Resonance Transmission Analysis (NRTA) is an …
