Abstract
The invention relates to a device for thermally stabilizing an object (20) to be cooled to a temperature of the order of 6 to 25 K by circulating a fluid, characterized in that it comprises: a Dewar flask (10) pressurized so as to provide a gas; a coaxial exchanger (11) for pre-cooling the gas; a cryostat (16) in which the object to be cooled is placed; a coaxial siphon (13) for transferring the gas from the Dewar vacuum flask to the cryostat, this siphon including at least one sieve (14) providing thermal filtration of the gas, and a variable flow outlet port (17) providing discharge of the gas.
Claims10
A device for thermally stabilizing an object (20) to be cooled at a predetermined temperature by circulating a fluid, characterized in that it includes:
- a pressure controlled Dewar flask (10) for providing a gas;
- a means (11, 26) for pre-cooling the gas;
- a cryostat (16) in which the object to be cooled is placed;
- a siphon (13) for transferring the gas from the Dewar flask to the cryostat;
- the siphon including within at least one sieve (14) providing thermal filtration of the gas, and
- a variable flow outlet port (17) providing discharge of the gas.
