Monte-Carlo calculation of production rates of cosmogenic radionuclides in a HPGe detector operating in the Modane underground laboratory

Popis výsledku v původním jazyce

Monte Carlo models based on GEANT4, CONUS and ACTIVIA software packages were used for simulation of production rates of cosmogenic radionuclides in the Obelix HPGe detector operating in the Modane underground laboratory. Interactions of secondary cosmic-ray nucleons with Ge-crystal (production of H-3, Mn-54, (CO)-C-57, Zn-65 and Ge-68), with copper in the cold finger (production of Sc-46, Mn-54, Co-56, Co-57, Co-58, Co-60 and Fe-59), with Al in bauxite ore (production of Al-26) and with Al-4%Si alloy in the cryostat (production of Na-22) were included in the calculations. The contribution of cosmogenic radionuclides to the total detector background of the Obelix detector decreased from 39% (after 10 months of cooling down) to 14% (after three years of cooling down). The calculated production rates of cosmogenic radionuclides and simulated gamma-ray spectra were in reasonable agreement with experimental results.
