<p>The invention concerns a device for thermal stabilisation of an object (20) to be cooled at a temperature of the order of 6 to 25 K by circulation. The invention is characterised in that it comprises a pressurised Dewar vase (10) to supply a gas, a coaxial exchanger (11) for pre-cooling the gas; a cryostat (16) wherein the object to be cooled is placed; a coaxial siphon (13) for transporting the gas from the Dewar vase to the cryostat, said coaxial siphon comprising, inside, at least a screen (14) for thermal filtering of the gas, and an outlet (17) with variable flow rate for evacuating the gas.</p> |
