AI Technical Summary

Problems solved by technology

The permissible vibration limit of high-performance precision instruments is within the submillimeter level, therefore, if a relatively large vibration is applied to the precision instrument, the internal structure and controllability of the precision instrument will be damaged, so the The above precision instruments will fail

Abstract

A stationary point is set on a cold end of a cryocooler. An article is mounted on the stationary point to be cooled via the stationary point. In this case, the article can be cooled up to an extremelylow temperature with isolation of vibration to the article.

Description

technical field [0001] The invention relates to a method of cooling an object using a cryogenic refrigerator and said cryogenic refrigerator. Background technique [0002] In superconducting filters in the IT communication field, in superconducting MRI in the medical field, or in the field of basic science, it is necessary to cool high-precision electron microscopes or high-performance precision instruments, such as high-sensitivity sub-millimeter detectors or infrared Detectors to eliminate thermal interference. When cooling the above-mentioned or existing high-performance precision instruments, a liquefied gas or a cryogenic refrigerator is often used. Recently, the cryogenic refrigerators have cooled down to 4K, which can be done simply by pressing a button, whereas in the past, this could only be achieved by using an ultra-low temperature coolant. [0003] figure 1 is a schematic diagram showing the structure of a conventional GM (Gifford McMahon) type cryogenic refri...
