Abstract

La présente invention a pour objet des dispositifs de grande sensibilité pour détecter les particules atomiques et les rayonnements ionisants. Un dispositif selon l'invention comporte un détecteur principal 1, fait de Ge (Li), placé à l'intérieur d'un enceinte étanche composée d'un capot qui enveloppe le détecteur et qui est connecté sur une enceinte 2b en dépression. Le capot 2a a la particularité d'être formé d'un matériau lui-même détecteur de particules et de radiations, par exemple d'un matériau scintillateur (plastique), et d'être recouvert sur sa face interne d'un film métallique très mince. Une application est l'équipement des spectromètres à coïncidence ou à anti-coïncidence, et notamment des spectromètres anti-Compton ou des spectmmètres à paires; dans ce cas ce dispositif, qui permet de supprimer l'effet absorbant des enveloppes protectrices usuelles, et de recueillir et détecter la totalité du rayonnement diffusé par le détecteur central, constitue un ensemble de détection idéal du rayonnement gamma nucléaire.
