Low-temperature microwave circuit for dilution refrigerator

Abstract

The invention belongs to the technical field of dilution refrigerators, and particularly relates to a low-temperature microwave circuit for a dilution refrigerator. The low-temperature microwave circuit comprises a dilution refrigerator, a gas transmission structure and a transmission structure, wherein the dilution refrigerator is provided with a box body, the inner wall of the box body is connected with a low-temperature microwave circuit structure through a fixing structure, and the low-temperature microwave circuit structure is electrically connected with the dilution refrigerator. The low-temperature microwave circuit further comprises a driving structure connected to one end of the gas transmission structure, and moving structures connected to the two ends of the box body, wherein one end of the driving structure is connected with the moving structure and an angle adjusting structure. According to the invention, the low-temperature microwave circuit structure can be effectively cooled and dust on a low-temperature microwave circuit can be cleaned through a cooling and cleaning structure, so that the use performance of the low-temperature microwave circuit structure can be improved, the service life of the low-temperature microwave circuit structure is prolonged, and the low-temperature microwave circuit has the advantage of small size.

Description

technical field [0001] The invention relates to the technical field of dilution refrigerators, in particular to a low-temperature microwave circuit for dilution refrigerators. Background technique [0002] Dilution refrigerator is the theory that H.London proposed in 1951 that superfluid 4He can be used to dilute 3He to refrigerate. By 1965, P.Das and others made a 3He-4He dilution refrigerator based on this theory, which has reached 1.8mK Low temperature, it can maintain the temperature in the range of milliK for a long time, and has a large cooling capacity. It has become the most important means and equipment to obtain the temperature of milliK, and the low-temperature microwave circuit is an indispensable circuit on the dilution refrigerator. Low-temperature microwave The line is generally set on the line. [0003] When most of the existing low-temperature microwave circuits are working, their heat dissipation effect is poor, which will reduce the performance of low-tem...
