A setup for Ba-ion extraction from high pressure Xe gas for double-beta decay studies with EXO

[摘要] An experimental setup is being developed to extract Ba ions from a high-pressure Xe gas environment. It aims to transport Ba ions from 10 bar Xe to vacuum conditions. The setup utilizes a converging-diverging nozzle in combination with a radio-frequency (RF) funnel to move Ba ions into vacuum through the pressure drop of several orders of magnitude. This technique is intended for use in a future multi-ton detector investigating double-beta decay in Xe-136. Efficient extraction and detection of Ba ions, the decay product of Xe-136, would allow for a background-free measurement of the Xe-136 double-beta decay. (C) 2013 Elsevier B.V. All rights reserved.
