Abstract

L'invention concerne un système et un procédé de détection et de localisation rapides et efficaces de substances explosives. L'appareil de détection comprend un faisceau pulsé de neutrons thermiques et un système de détection de rayons gamma. Le faisceau pulsé de neutrons thermiques est produit en modérant des neutrons à des énergies thermiques en un temps réduit, avec une extraction rapide des neutrons thermiques dans la direction de la substance à interroger, avec un temps d'extinction des neutrons thermiques plus court que le temps de vol entre la source et la substance interrogée. Des rayons gamma rayonnés de façon isotrope sont détectés par le système de détection de rayons gamma, qui est placé à l'écart de la source de neutrons. La distribution temporelle du taux de comptage obtenu dans les différentes régions d'intérêt (ROI) discriminées par l'énergie se produit lorsqu'il n'existe aucun effet pratique de l'arrière-plan synchrone du fait de l'interaction directe entre la source de neutrons et le système de détection de rayons gamma.
