Muon-Induced Neutron Background SIMULATION OF THE MUON-INDUCED NEUTRONS: Transportation of muons from the Earth’s surface down to the underground laboratory is simulated with MUSIC code (neutron yield strongly depends on the depth of the experimental hall and the mountain profile). Used data for LNGS from: P. Antonioli et al., Astrop. Phys. 7 357 (1997), V.A.Kudryavtsev et al., Phys. Lett. B471 251 (1999). Calculation of the angular distribution and the energy spectra at the experimental site is carried out with MUSUN code (sampling single atmospheric muons at the Gran Sasso laboratory, taking into account the slant depth distribution).
