Abstract: Aspects of a vibrationally isolated cryogenic shield for local high-quality vacuum are described. More specifically, a cryogenic vacuum system is described that is 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 ensures that paths from outgassing materials to the control volume, including 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 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 isolated along with the cryogenic system via soft vacuum bellows.
