| titleOfInvention | Method and device for precooling a cryostat |
| abstract | Method for operating a cryostat with a vacuum container, in which a chamber with at least one object to be cooled (10, 10 ') is arranged, wherein at least one hollow cold head tower (12) is provided on the vacuum container into which a neck tube (4) protrudes which connects the chamber through the outer jacket (8, 8 ') of the vacuum container to the region outside the cryostat, wherein the neck tube (4) is geometrically designed so that a cold head (1) can be introduced, comprising a cold head stage (7 ), with which a cryogenic working medium can be cooled, which thereby condenses and flows in a condensation operation through a heat pipe (5) in an evaporator chamber (6) or drops, which via a thermal contact surface (9, 9 ') with the cooled Object (10; 10 ') is thermally conductively connected, so that the cooled cryogenic working medium absorb heat from the object to be cooled (10; 10') and via the heat pipe (5) to the cold head stage (7 ), characterized, in that the object to be cooled (10; 10 ') is pre-cooled to a target temperature of the working range of the cryogenic working medium in which the heat pipe (5) can work efficiently, wherein a good heat-conducting, accurately fitting short-circuit block (14) by the Neck tube (4) is inserted into the heat pipe (5), whose one free end is thermally connected to a powerful cooling device (13), the other end of the thermal contact surface (9, 9 '), that in an intermediate phase after reaching the target temperature, the short-circuiting block (14) is removed from the heat pipe (5), and that subsequently during an operating phase heat is transferred through the heat pipe (5) in the condensation mode. |
