  • Cryogenically cooled vacuum chamber radiation shields for ultra-low temperature experiments and extreme high vacuum (XHV) conditions
    Patent number: 11946598
    Abstract: Methods, systems, and devices for ultra or extreme-high vacuum are described. Such systems may comprise a vacuum chamber, a target within the vacuum chamber, two or more overlapping radiation shields arranged within an inner vacuum space of a vacuum chamber, and surrounding at least a portion of the target, a first and a second cooling element unit thermally coupled to a first and second radiation shield of the two or more overlapping radiation shields, wherein the first unit is configured to reduce the first radiation shield's temperature to at least <100K, and the second unit is configured to reduce the second radiation shield's temperature to at least <25K, and a third cooling element unit coupled to the target and isolated from the first and second radiation shield, wherein the third cooling element unit is configured to reduce the target's temperature to at least <4K.
