Abstract

Dispositif caractérisé en ce qu'il comporte d'une part une unité de refroidissement à cycle de Stirling ou à gaz pulsé (10) constituée par module de compression (16) coopérant avec un doigt froid (17), relié à une source de courant alternatif et équipé de moyens susceptibles de faire varier périodiquement la pression d'un gaz de travail à haute pression, notamment de l'hélium remplissant une chambre de travail subdivisée en plusieurs compartiments et s'étendant dans le module de compression (16) et dans le doigt froid (17) de façon à provoquer dans un compartiment froid situé à l'extrémité du doigt froid (17) opposée au module de compression (16) ou première extrémité (18) une détente du gaz de travail permettant d'obtenir de très basses températures à ce niveau, et d'autre part des organes de transmission de la chaleur à contact sec (11) montés sur le doigt froid (17) au niveau de la première extrémité (18) de celui-ci et coopérant avec la cellule renfermant l'échantillon à analyser de façon à permettre de refroidir cet échantillon à la température souhaitée.Device characterized in that it comprises on the one hand a Stirling cycle or pulsed gas cooling unit (10) constituted by compression module (16) cooperating with a cold finger (17), connected to a current source alternative and equipped with means capable of periodically varying the pressure of a high pressure working gas, in particular helium filling a working chamber subdivided into several compartments and extending in the compression module (16) and in the cold finger (17) so as to cause in a cold compartment located at the end of the cold finger (17) opposite the compression module (16) or first end (18) an expansion of the working gas making it possible to obtain very low temperatures at this level, and on the other hand dry contact heat transfer members (11) mounted on the cold finger (17) at the first end (18) thereof and cooperating with the cell containing the sample to be analyzed so as to allow this sample to cool to the desired temperature.
