Description
As observed in XENON1T, tritium, which exists as an impurity in liquid xenon, can potentially contribute to background signals in direct dark matter detection experiments using liquid xenon. Therefore, this study aims to measure hydrogen concentrations at the ppt level in gaseous xenon to quantitatively evaluate tritium concentration. This poster presents the current progress in trace hydrogen measurement in argon gas using a residual gas analyzer and a hydrogen separation membrane module.
