Abstract

GENIUS is a proposal for a large-scale detector of rare events like double beta decay, cold dark matter and low-energy solar neutrinos in real time. The idea of GENIUS is to operate a large amount of "naked" Ge detectors in liquid nitrogen, with the aim of reducing the background down to a level of 10-3 counts/kgkeVyr. In this work, we investigate the contribution to the background of GENIUS coming from argon (³⁹Ar) and krypton (⁸⁵Kr) contamination in the liquid nitrogen.
