Monte Carlo Simulation of Homestake Background
ORAL
Abstract
Background characterization is critical to the shielding design for the incoming DUSEL experiments. A simulation is performed by applying the composition of Homestake rock samples. Then the neutron and gamma ray fluxes as a function of energy induced by natural radioactivity at Homestake mine are calculated. In particular, utilizing the rock radioactivity counted by Al Smith at LBL, the neutron flux and gamma-ray flux at the 4850-level and 7400-level are predicted. The results can be used as a reference for the shielding design for low background experiments planned at DUSEL.
