Construction and measurements of a vacuum-swing-adsorption radon-mitigation system [PDF]
AIP Conference Proceedings, 2013 Long-lived alpha and beta emitters in the $^{222}$Rn decay chain on (and near) detector surfaces may be the limiting background in many experiments attempting to detect dark matter or neutrinoless double-beta decay, and in screening detectors. In order to reduce backgrounds from radon-daughter plate-out onto the wires of the BetaCage during its ...

Temperature vacuum swing, a combined adsorption cycle for carbon capture
Current Opinion in Chemical Engineering, 2023 Since its development in the early 20th century, the adsorptive separation process has evolved tremendously in terms of both adsorbent and process. Particular development is the hybrid temperature vacuum swing adsorption (TVSA) process. This review addresses the current and potential applications of this technology for carbon capture and explores the ...
