Pilot full-scale demonstration of a prototype table-top neutron resonance transmission analysis system for nuclear material detection.

ABSTRACT: Neutron Resonance Transmission Analysis (NRTA) is a highly sensitive, non-destructive technique for nuclear material characterisation, but its application has been limited by its reliance on large, fixed, and costly installations. Here, we present a compact mobile NRTA system utilising a small ²⁵²Cf spontaneous neutron source, designated as a prototype "table-top NRTA system", to analyse nuclear materials, offering a mobile and cost-effective alternative to accelerators or deuterium-tritium generators. The pilot system, measuring 130 cm × 50 cm × 50 cm with a 42 cm flight path, enables time-of-flight measurements on nuclear material samples. The system's performance was demonstrated through NRTA measurements of simulated samples, including indium, hafnium, and cadmium metal plat
