We demonstrate the ability to obtain the direction of the gamma rays using a standard coaxial high purity germanium (HPGe) detector using the direction-sensitive information embedded in the shape of the pre-amplified HPGe signals. We deduced the complex relationship between the shape of the signal and the direction from which the gamma-ray enters t...

Neutron scatter cameras are a type of directional neutron detectors that rely on multiple neutron scatters to generate images that can reveal the direction and distribution of neutron sources. Fast neutron cameras which have recently been developed rely on multiple detector volumes and make use of neutron time-of-flight measurements. These designs,...

Neutron scatter cameras (NSCs) are a type of directionally sensitive neutron detector that rely on two consecutive neutron scattering events to localize a source of neutrons. NSCs can be used to locate, image, and identify unknown neutron sources or verify the geometry and identity of known sources. Much technical progress has been made in improvin...

A fast neutron scatter camera is sought for the purposes of localizing neutron emitting sources for nuclear safeguards and security purposes. Localization of a neutron source entails determining the general direction of a source in 3-D space rather than imaging or identifying the type of source. Fast neutron cameras which have been developed rely o...

A tin-loaded liquid scintillator has been developed for gamma spectroscopy and neutron detection. The scintillator was characterized in regard to energy resolution, pulse shape discrimination, neutron light output function, and timing resolution. The loading of tin into scintillators with low effective atomic number was demonstrated to provide phot...

A tin doped viscous gel scintillation material is being developed to increase the peak to total ratio for gamma ray detection. Detectors with such material would excel at many applications, including characterizing nuclear material for safeguards and nonproliferation. The current iteration of the material has been characterized for its detection pr...
