Muon-induced background study for underground laboratories
305 citations recorded by the source corpus.
We provide a comprehensive study of the cosmic-ray muon flux and induced activity as a function of overburden along with a convenient parametrization of the salient fluxes and differential distributions for a suite of underground laboratories ranging in depth from {approx}1 to 8 km.w.e.. Particular attention is given to the muon-induced fast neutron activity for the underground sites and we develop a depth-sensitivity relation to characterize the effect of such background in experiments searching for WIMP dark matter and neutrinoless double-beta decay.

- Solar fusion cross sections II: the pp chain and CNO cycles (2010, background): “The laboratory’s depth, ∼ 3.0 km.w.e. (kilometers of water equivalent, flat-site equivalent (Mei and Hime, 2006)), reduces the fluxes of muons and secondary neutrons, relative to surface values, by factors of 106 and 103, respectively.”
- Double Beta Decay, Majorana Neutrinos, and Neutrino Mass (2007, background): “Mei and Hime (Mei and Hime, 2006) estimate that a depth of 5 km.w.e. (flat overburden) would greatly reduce veto-system requirements.”
- Physics reach of the XENON1T dark matter experiment. (2015, unknown): “Assuming conservative values for the muon-induced neutron yield [61], and considering the effect of both the passive shielding of the water and the active veto, the surviving neutron background is < 0.”
- Search for dark matter with a 231-day exposure of liquid argon using DEAP-3600 at SNOLAB (2019, methodology): “ing muons with the energy spectra described by [44] results in a prediction of NCR n;csg < 0.”
- Directional detection of dark matter with two-dimensional targets (2016, background): “or greater, as would be the case for an underground lab like Gran Sasso or SNOLAB, the total flux of muons across the entire graphene target falls below 10−1 s−1 [51].”
