Description
The goal of the SuperNEMO experiment is the search for neutrinoless double-beta decay (0𝜈𝛽𝛽), the observation of which would prove that the neutrino is a Majorana particle. As 0𝜈𝛽𝛽 is a hypothetical and extremely rare process, it is essential to have the lowest level of background possible. 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 Qb=3.27 MeV can contribute to the double-beta background. The 222Rn activity inside the SuperNEMO tracker demonstrator module must be significantly reduced down to 0.15 mBq/m3. This poster will detail anti-radon strategies used in SuperNEMO and present the status of the 222Rn analysis based on first data compared to simulation using the topology of the 214Bi-214Po decay event, i.e. one electron followed by a delayed alpha.
