The radioactive daughters isotope of 222Rn are one of the highest risk contaminants in liquid xenon detectors aiming for a small signal rate. The noble gas is permanently emanated from the detector surfaces and mixed with the xenon target. Because of its long half-life 222Rn is homogeneously distributed in the target and its subsequent decays can mimic signal events. Since no shielding is possible this background source can be the dominant one in future large scale experiments. This article… 

Overview of Radon Background Correction Technology for Airborne Gamma Spectrometry

In radiometric measurements, the radiation characteristics of radon and its daughters will increase the detection background value and affect the detection results. Research institutes in various

Barium Chemosensors with Dry-Phase Fluorescence for Neutrinoless Double Beta Decay

Two families of dry-phase barium chemosensor molecules for use in high pressure xenon gas detectors are synthesized specifically for this purpose, and one particularly promising candidate is shown to respond in the dry phase with almost no intrinsic background from the unchelated state, and to be amenable to barium sensing through fluorescence microscopy.

Mitigation of 222Rn induced background in the XENON1T dark matter experiment

222Rn is a major source of background in many rare-event experiments such as the XENON1T dark matter search. The noble gas radon is created by radioactive decay inside all detector materials and

Intrinsic backgrounds from Rn and Kr in the XENON100 experiment

AbstractIn this paper, we describe the XENON100 data analyses used to assess the target-intrinsic background sources radon ( ), thoron ( ) and krypton ( ). We detail the event selections of

Radon removal from gaseous xenon with activated charcoal

Radon depletion in xenon boil-off gas

An important background in detectors using liquid xenon for rare event searches arises from the decays of radon and its daughters. We report for the first time a reduction of $$^{222}$$222Rn in the

Radon and material radiopurity assessment for the NEXT double beta decay experiment

Krypton and radon background in the PandaX-I dark matter experiment

We discuss an in-situ evaluation of the 85Kr, 222Rn, and 220Rn background in PandaX-I, a 120-kg liquid xenon dark matter direct detection experiment. Combining with a simulation, their contributions

Intrinsic 85Kr and 222Rn Backgrounds in the XENON Dark Matter Search

The XENON Dark Matter search is aiming for the direct detection of Dark Matter in the form of weakly interacting massive particles (WIMPs) scattering off xenon nuclei. This process is expected to

Online $$^{222}$$222Rn removal by cryogenic distillation in the XENON100 experiment

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
