Muon-induced background in a next-generation dark matter experiment based on liquid xenon

Popis výsledku v původním jazyce

Muon-induced neutrons can lead to potentially irreducible backgrounds in rare event search experiments. We have investigated the implication of laboratory depth on the muon-induced background in a future dark matter experiment capable of reaching the so-called neutrino floor. Our simulation study focuses on a xenon-based detector with 71 tonnes of active mass, sur-rounded by additional veto systems including an instrumented water shield. Two locations at the Boulby Underground Laboratory (UK) served as a case study: an experimental cavern in salt at a depth of 2850 m w. e. (similar to the location of the existing laboratory), and a deeper laboratory located in polyhalite rock at a depth of 3575 m w. e. Our results show that less than one event of cosmogenic background is likely to survive standard analysis cuts for 10 years of operation at either location.
