Device for explosive detection

Creators

Description

The object is irradiated by 7-14 MeV neutrons from a generator, prompt gamma radiations emitted by the object are analysed with a germanium detector and associated electronic circuits for determination of the ratio nitrogen/oxygen which characterizes most of the explosives. Application is made to suspect parcels testing

Abstract (French)

Il comprend par exemple un generateur de neutrons de 14 MeV pour envoyer ces neutrons sur un objet susceptible de contenir un explosif, un detecteur au germanium et des moyens d'analyse couples au detecteur et aptes a analyser les photons γ prompts emis par l'objet et captes par le detecteur, et a determiner le rapport azote/oxygene dans l'objet, afin que l'on puisse comparer ce rapport a celui de l'explosif et savoir si l'objet en contient. Application a l'examen de colis suspects
