Neutron detection is an integral part of the global effort to prevent the proliferation of special
nuclear material (SNM). Applications relying on neutron-detection technology range from …

Active interrogation is a vigorous area of research and development due to its promise of
offering detection and characterization capabilities of special nuclear material in …

High-temperature gas reactors rely on TRIstructural-ISOtropic (TRISO) fuel for enhanced
fission product retention. Accurate fuel characterization would improve monitoring of efficient …

The detection and characterization of highly enriched uranium (HEU) presents a large
challenge in the non-proliferation field. HEU has a low neutron emission rate and most …

Detection of several targets (U, Be, D 2 O) of interest to national security has been achieved
at Purdue University's 6 MV X-ray clinical linear accelerator (CLINAC), from …

Advances in neutron science have gone hand in hand with the development of particle
accelerators from the beginning of both fields. Early accelerator systems were developed …

Detection of unique signatures of special nuclear materials is critical for their interdiction in a
variety of nuclear security and nonproliferation scenarios. We report on the observation of …

Delayed neutron counting is often used to verify the characteristics of nuclear material. Use
of portable neutron generators in high frequency pulsing mode enables effective analysis …

The interaction of radiation with matter can cause activation or fission reactions producing
unstable residuals that decay with the emission of delayed-neutron and/or delayed-gamma …

The paper reports the development of a RF ion source-based transportable compact neutron
generator and its application in detecting special nuclear material using the differential die …
