Radon contamination measurement in the SuperNEMO demonstrator
Original language description
The neutrino, as a neutral particle can be identical to its antiparticle, i.e, a Majorana particle. SuperNEMO aims at searching for the neutrinoless double beta decay (0vββ), whose observation would prove that the neutrino is a Majorana particle. The 0vββ process, beyond the Standard Model, is very rare and the level of background should be extremely small. One source of background comes from the 222Rn emanation from the detector components or diffusion from the air of the laboratory towards the tracker. The daughter isotope, of 222Rn, the 214Bi can by (β, γ) disintegration produce two electrons with an energy around 3 MeV and therefore constitute a source of background for 0vββ. The SuperNEMO demonstrator should prove the capacity to reduce the 222Rn activity to to a level less than 0.15 mBq/m3. Here, I present the preliminary measurement of the 222Rn activity in the demonstrator, based on first data acquired without shieldings, without injection of Radon free air in the antiradon tent, and purification of the tracker gas by the Radon trap.
