摘要： The disclosure describes various aspects of a vibrationally isolated cryogenic shield for local high-quality vacuum. More specifically, the disclosure describes a cryogenic vacuum system replicated in a small volume in a mostly room temperature ultra-high vacuum (UHV) system by capping the volume with a suspended cryogenic cold finger coated with a high surface area sorption material to produce a localized extreme high vacuum (XHV) or near-XHV region. The system is designed to ensure that all paths from outgassing materials to the control volume, including multiple bounce paths off other warm surfaces, require at least one bounce off of the high surface area sorption material on the cold finger. The outgassing materials can therefore be pumped before reaching the control volume. To minimize vibrations, the cold finger is only loosely, mechanically connected to the rest of the chamber, and the isolated along with the cryogenic system via soft vacuum bellows.

摘要： A superconducting magnet assembly may include a switch component including a first thermal switch and/or a second thermal switch. The first thermal switch may include a first activation mode configured to facilitate heat transfer between a first stage cold head and a radiation shield, and a first deactivation mode configured to break or impede the heat transfer between the first stage cold head and the radiation shield. The second thermal switch may include a second activation mode configured to facilitate heat transfer between a second stage cold head and a superconducting magnet, and a second deactivation mode configured to break or impede the heat transfer between the second stage cold head and the superconducting magnet.

摘要： Thermal energy transmission from a cryocooler cold finger is enhanced by means of a high thermal conductivity material used for or placed adjacent the cold finger end cap. In addition, the actual or effective surface area contacted by the working gas proximate the endcap is increased, thereby increasing the convective heat transfer coefficient. These features permit the coolest gas expansion space in the cold finger to be provided within the highly thermally conductive end cap, unlike many conventional designs in which the cold finger of low thermally conductive metal forms the expansion space side walls and the endcap forms only the axially facing outer surface in contact with the cooled equipment. Having the expansion space built into the high thermally conductive end cap reduces the temperature drop between the load to be cooled and the gas (e.g., helium), thus increasing the thermodynamic cycle efficiency.
