Abstract

To study the risks associated with neutron fields from various sources, direct measurements using advanced detection technologies are essential. This study explores the Thermal Neutron Imaging System (TENIS) for characterizing the energy spectrum of an (α, n) neutron beam generated in the collimated channel of the Prizm-AN facility utilizing an IBN-10 source. We present the performance characteristics of the neutron beam, the permissible operational duration near the installation, a comprehensive map of thermal neutron flux parameters, and the results of spectrum unfolding achieved using artificial neural networks (ANNs). Our analysis confirms that TENIS can effectively measure the energy spectrum of slowed-down (α, n) neutrons produced under horizontal collimation. Additionally, we highlight the similarities between ^2,3H fusion and (α, n) reactions, integrating the Prizm-AN complex with TENIS as a powerful tool for the real-time monitoring and control of plasma parameters within the paired plasma source neutrons (PSN) and variable-geometry beam-shaping assembly (vBSA) system.

期刊介绍： Radiation Physics and Chemistry is a multidisciplinary journal that provides a medium for publication of substantial and original papers, reviews, and short communications which focus on research and developments involving ionizing radiation in radiation physics, radiation chemistry and radiation processing. The journal aims to publish papers with significance to an international audience, containing substantial novelty and scientific impact. The Editors reserve the rights to reject, with or without external review, papers that do not meet these criteria. This could include papers that are very similar to previous publications, only with changed target substrates, employed materials, analyzed sites and experimental methods, report results without presenting new insights and/or hypothesis testing, or do not focus on the radiation effects.
