Claim 0:
1. An ultra-high vacuum (UHV) or extreme-high vacuum (XHV) system comprising:
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, wherein the two or more overlapping radiation shields surround at least a portion of the target;
a first cooling element unit thermally coupled to a first radiation shield of the two or more overlapping radiation shields, wherein the first cooling element unit is configured to reduce the first radiation shield's temperature to at least <100K;
a second cooling element unit thermally coupled to a second radiation shield of the two or more overlapping radiation shields, wherein the second cooling element unit is configured to reduce the second radiation shield's temperature to at least <25K; and
a third cooling element unit thermally coupled to the target, the third cooling element unit thermally isolated from both the first radiation shield and the second radiation shield, wherein the third cooling element unit is configured to reduce the target's temperature to at least <4K.
