Abstract

La présente invention se rapporte à un dispositif cryostatique permettant le refroidissement d'un élément photodétecteur 4 au moyen du doigt froid 1 d'une machine cryogénique 2. L'enceinte à vide primaire 12 formée par le doigt froid 1 et le vase Dewar renfermant l'élément photodétecteur 4 est fermée par un soufflet métallique 13 en extension assurant simultanément l'étanchéité de cette enceinte et le contact thermique dudit doigt froid. La surface extérieure du dispositif est rectifiée et maintient la position angulaire du photodétecteur 4 de façon précise au moyen d'un joint torique 18 souple relié par trois colonnes 20 à la machine cryostatique. Application aux ensembles cryostatiques photodétecteurs.
