Low radon and low internal radioactivity for dark matter and rare event xenon detectors (LowRad)
Basic data for this project
Description
Two leading collaborations – the XENON/DARWIN and LUX-ZEPLIN (liquid xenon detectors) – that study dark matter are joining forces to create the next-generation dark matter detector. The detector will also be sensitive to other rare physics processes, such as the neutrinoless double beta decays, solar neutrinos, axions, etc. Despite the existence of shielding systems for muons or neutrons, the sensitivity of both detectors is limited by radioactive decays within the xenon, especially of the radioactive noble gas isotopes 222Rn and 85Kr. The EU-funded LowRad project will establish cryogenic distillation set-ups to reduce the concentrations of 222Rn and 85Kr to unprecedented levels. These should help reduce their background contributions to the detector by a factor of 10.
