Scintillator based coded-aperture imaging has proven to be effective when applied for X-and
gamma-ray detection. Adaptation of the same method for neutron imaging has resulted in a …

We introduce a neutron-gamma emission tomography (NGET) technique for rapid detection,
three-dimensional imaging, and characterization of special nuclear materials like weapons …

A compact radiation imaging system capable of detecting, localizing, and characterizing
special nuclear material (eg highly-enriched uranium, plutonium…) would be useful for …

We describe a very compact (0.9 m high, 0.4 m diameter, 40 kg) battery operable neutron
scatter camera designed for field deployment. Unlike most other systems, the configuration …

A dual-particle imager (DPI) is configured in a hand-held form factor, then one can efficiently
and conveniently deploy the DPI to detect the presence of special nuclear materials (SNM) …

The gamma-ray response of thick pixelated CdZnTe detectors varies spatially but is
relatively constant as a function of time. Detector irregularities arise from flaws in the …

This brief report describes commissioning measurements performed using a newly
constructed fastneutron coded-aperture imager intended for performing quantitative …

The development of compact and portable neutron imagers could be transformative for
nuclear nonproliferation and security. Of the currently feasible neutron imaging concepts, the …

Time-encoded imaging is useful for identifying potential special nuclear materials and other
radioactive sources at a distance. In this study, a large field-of-view time-encoded imager …

We report on the characterization efforts on a largescale, coded-aperture imager for fast
neutrons at the US Naval Research Laboratory. The fast neutron imager discussed in this …
