A cryostat configuration with a vacuum vessel (1) and a cryogen vessel (2) built into it, and a sleeve (8), into which a cryocooler (7) is built, wherein the upper, warm end of the sleeve is connected to the outer jacket and the lower, cold end facing the cryogen vessel is hermetically sealed by a sleeve base (9) is characterized in that the cryogen vessel is hermetically sealed except for a gas capillary (13) and filled with gaseous fluid (12) at a pressure below the vapor pressure of the liquid phase of the fluid at the corresponding operating temperature and the coldest stage of the cryocooler is connected to the heat exchanger (11) disposed inside the cryogen vessel in a manner that ensures good thermal conduction.
