Removing krypton from xenon by Cryogenic Distillation to the ppq level
The European Physical Journal C, 2017Co-Authors: E Aprile, J Aalbers, F Agostini, M Alfonsi, F D Amaro, M Anthony, F Arneodo, P Barrow, L Baudis, B BauermeisterAbstract:The XENON1T experiment aims for the direct detection of dark matter in a detector filled with 3.3 tons of liquid xenon. In order to achieve the desired sensitivity, the background induced by radioactive decays inside the detector has to be sufficiently low. One major contributor is the $$\beta $$ β -emitter $$^{85}$$ 85 Kr which is present in the xenon. For XENON1T a concentration of natural krypton in xenon $$\mathrm {^{nat}\mathrm{Kr/Xe}\,

online 222 rn removal by Cryogenic Distillation in the xenon100 experiment
European Physical Journal C, 2017Co-Authors: E Aprile, J Aalbers, F Agostini, M Alfonsi, F D Amaro, M Anthony, F Arneodo, P Barrow, L Baudis, B BauermeisterAbstract: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 $$^{222}$$ Rn background originating from radon emanation. After inserting an auxiliary $$^{222}$$ Rn emanation source in the gas loop, we determined a radon reduction factor of $$R\,>\,27$$ (95% C.L.) for the Distillation column by monitoring the $$^{222}$$ Rn activity concentration inside the XENON100 detector.

removing krypton from xenon by Cryogenic Distillation to the ppq level
European Physical Journal C, 2017Co-Authors: E Aprile, J Aalbers, F Agostini, M Alfonsi, F D Amaro, M Anthony, F Arneodo, P Barrow, L Baudis, B BauermeisterAbstract:The XENON1T experiment aims for the direct detection of dark matter in a detector filled with 3.3 tons of liquid xenon. In order to achieve the desired sensitivity, the background induced by radioactive decays inside the detector has to be sufficiently low. One major contributor is the \(\beta \)-emitter \(^{85}\)Kr which is present in the xenon. For XENON1T a concentration of natural krypton in xenon \(\mathrm {^{nat}\mathrm{Kr/Xe}\,<\,200\,ppq}\) (parts per quadrillion, \(1~\mathrm{ppq}~=10^{-15} \mathrm{mol/mol}\)) is required. In this work, the design, construction and test of a novel Cryogenic Distillation column using the common McCabe–Thiele approach is described. The system demonstrated a krypton reduction factor of \(6.4\cdot 10^5\) with thermodynamic stability at process speeds above 3 kg/h. The resulting concentration of \(\mathrm {^{nat}\mathrm{Kr/Xe}<26\,ppq}\) is the lowest ever achieved, almost one order of magnitude below the requirements for XENON1T and even sufficient for future dark matter experiments using liquid xenon, such as XENONnT and DARWIN.
