Characterization of fissile material using low energy neutron interrogation
… in the exploration of various methods for active neutron interrogation, specifically for the presence of special nuclear material (SNM) in cargo containers. The proposed system aims to defeat the ability of terrorists to import SNM into the United States via maritime shipping, thus greatly …

Non-destructive inspection of spent fuel casks through 14.1 MeV neutron interrogation
Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2025-05-01

Monte Carlo model of a low-energy neutron interrogation system for detecting fissile material
(cont.) Further MCNP simulations of the neutron source impinging on cargo containers suggest that this technique can respond, as expected, qualitatively differently to containers containing SNM from containers that do not. Containers that contain small amounts of fissile isotopes as in the case of …

Neutron Resonance Transmission Analysis of Nuclear Material Using a Portable D-T Neutron Generator
… capacity to analyze thick or shielded targets. Neutron Resonance Transmission Analysis (NRTA) is an active neutron interrogation technique that addresses these challenges by offer- ing isotope-specificity, applicability to a wide range of mid- and high-Z isotopes, and the ability to assay …

Compact Capabilities: Developing and Evaluating a Field-Portable Neutron Resonance Capture Analysis System
… an experimental evaluation of a portable Neutron Resonance Capture Analysis (NRCA) system sensitive to isotopes with neutron capture resonances in the epithermal range (1-100 eV). NRCA is a technique traditionally used for nuclear data collection and nondestructive assay of archaeological …

Doppler-Broadening of Light Nuclei Gamma-Ray Spectra
<p>Non-destructive methods of material interrogation are used to locate hidden explosives and thwart terrorism attempts. In one such method materials are bombarded with neutrons which react with the nuclei of the atoms within causing a de-excitation process emitting a gamma-ray. The spectrum …
