Abstract: A cryostat for providing temperature regulation, one purpose being measuring physical properties of materials, the cryostat employing a superconducting magnet assembly for generating variable magnetic field in the sample space and a cryogenic cooler for cooling the sample space. The cryogenic cooler chamber configuration provides for efficient heat exchange between different stages of the cryogenic cooler without the need for physical heat links. This construction enables selective delivery of cooling power from the cryogenic cooler to the desired areas within the cryostat without using flexible physical thermal links. A counter flow exchanger and ambient temperature valves facilitate efficient use of the cryogenic cooler stages. The removal of large heat load generated by the superconducting magnet while operating in the sweeping mode is achieved, in part, by employing a solid plate thermal coupling element between the cryogenic cooler chamber and the magnet assembly.
