Abstract
Abstract We describe the purification of xenon from traces of the radioactive noble gas radon using a cryogenic distillation column. The distillation column was integrated into the gas purification loop of the XENON100 detector for online radon removal. This enabled us to significantly reduce the constant $$^{222}$$ 222 Rn background originating from radon emanation. After inserting an auxiliary $$^{222}$$ 222 Rn emanation source in the gas loop, we determined a radon reduction factor of $$R\,>\,27$$ R > 27 (95% C.L.) for the distillation column by monitoring the $$^{222}$$ 222 Rn activity concentration inside the XENON100 detector.
