Patent ID: 11480299

Abstract:
A cryostat, such as for a quantum computing system, includes a plurality of temperature-controlled flanges operable to be cooled to respective cryogenic target temperatures, the temperature-controlled flanges being nested one inside another and concentrically arranged about a central axis. The temperature-controlled flanges are radially spaced apart and define closed polygonal perimeters. The temperature-controlled flanges including an outermost flange defining a vacuum chamber, an innermost flange enclosing a central core of the cryostat, and intermediate flanges radially located between the innermost flange and the outermost flange. Each of the intermediate flanges surrounds one or more of the other temperature-controlled flanges. The outermost flange is maintained at a highest temperature, the innermost flange is maintained at a lowest temperature, and the intermediate flanges are maintained at respective intermediate temperatures less than the highest temperature and greater than the lowest temperature.
