Study of Radon backgound in the SuperNEMO demonstrator
Original language description
The goal of the SuperNEMO experiment is to search for neutrinoless double-beta decay (0νββ) process, the observation of which would prove that the neutrino is a Majorana particle. 222Rn is a gaseous isotope which could emanate from the detector materials or diffuse from the air of the laboratory into the detector, and its daughter isotope 214Bi with Qβ = 3.27 MeV can contribute to the background. The 222Rn activity inside the SuperNEMO tracker demonstrator module must be significantly reduced down to 0.15mBq.m-3. This paper will present anti-radon strategies used in SuperNEMO and present a status of the 222Rn analysis based on first data using the topology of the 214Bi - 214Po decay event, i.e. one electron followed by a delayed alpha with preliminary results.
