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

An experimental setup is being developed to extract Ba ions from a high-pressure Xe gas environment. It aims to transport Ba ions from 10bar 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...

Zusammenfassung:An experimental setup is being developed to extract Ba ions from a high-pressure Xe gas environment. It aims to transport Ba ions from 10bar 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 136Xe. Efficient extraction and detection of Ba ions, the decay product of 136Xe, would allow for a background-free measurement of the 136Xe double-beta decay.
