Measurement of the cosmic-induced neutron yield at the Modane underground laboratory

Muon-induced neutrons (µ-ind. n's) are an important background source for Dark Matter searches, e.g. EDELWEISS at Laboratoire Souterrain de Modane (LSM). Within this work, a data set of 313 µ-ind. n's at LSM was collected. Using Geant4 and a calibrated detector response model, the absolute neutron rate is reproduced within 15% and agrees within the uncertainties. This work demonstrates that Geant4 can reliably model the production of µ-ind. n's once a detailed model is implemented.
