Abstract

L'INVENTION A POUR OBJET UN ETAGE HERMETIQUE DE REFRIGERATION DE FAIBLE DIMENSION CONTENANT DE L'HELIUM 3 ET AISEMENT INCORPORE A UN CRYOSTAT METALLIQUE A HELIUM 4 CLASSIQUE. L'ETAGE CONSISTE ESSENTIELLEMENT EN UNE ENCEINTE METALLIQUE 11 RENFERMANT UN CERTAIN VOLUME D'HELIUM 3 ET COMPRENANT UN PREMIER RECIPIENT 12 CONSTITUANT L'ENCEINTE DE POMPAGE AVEC UNE MASSE D'UN CORPS ADSORBANT POUR L'HELIUM 3 A TRES BASSE TEMPERATURE, UN SECOND RECIPIENT 15 CONSTITUANT CONDENSEUR POUR L'HELIUM 3 REFROIDI ET UN CONDUIT 16. L'INVENTION S'APPLIQUE PARTICULIEREMENT POUR MAINTENIR A UNE TEMPERATURE INFERIEURE A 1K L'ELEMENT SENSIBLE DE DETECTEUR INFRAROUGE.
