85Kr and 39Ar background in GENIUS
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/kg keV yr . In this work, we investigate the contribution to the background of GENIUS coming from argon ( 39Ar) and krypton ( 85Kr) contamination in the liquid nitrogen.
