Abstract / Description:Neutrons can create background in experiments built to search for rare events like neutrinoless double beta decay. They can generate long lived isotopes in the materials used in the experiment. Although neutrons can be shielded during storage and transportation, muons penetrate and can produce neutrons inside the shield and the material to be shielded. Since the expected signal rates are extremely low, understanding and reducing of background plays a crucial role for rare event searches. Therefore it is important to know the shielding properties and the muon-induced neutron rate of the shielding materials. To determine the shielding properties of different materials, cosmic-ray neutrons and muons were simulated with the GEANT4 based framework MaGe. Since the angular distribution at sea level is not precisely known, different neutron angular distributions were evaluated. In addition, the influence of neutron back-scattering was investigated.
