Abstract

Cryostat comportant un récipient central rempli d'un premier gaz liquéfie et entouré d'un dispositif formant écran dont la température est celle d'un autre gaz liquéfié dont le point d'ébullition est plus élevé, et un récipient extérieur à température ambiante, ledit cryostat étant caractérisé en ce qu'il comprend en outre un écran de rayonnement disposé entre la surface intérieure du récipient exterieur et la surface extérieure dudit dispositif formant ecran, et un dispositif de réfrigération destiné à maintenir l'écran de rayonnement à une température située entre celle du dispositif formant écran et la température ambiante.
