The chosen way to improve sensitivity for doublebeta search is to build a SuperNEMO detector, based on the same detection principle as the NEMO-3 detector: firstly, reconstruction of the trajectories of the 2 electrons, then measurement of their energies and arrival time by calorimeters.The goal of the SuperNEMO detector is to reach a sensitivity on the order of 10{sup 26} year on the half-life of the process of double beta decay without neutrino emission. The chosen isotopes for the future detector are {sup 82}Se and {sup 150}Nd, because of the reduced background.The collaboration has started a 3-year R and D developpement on all components: tracking detector, calorimeter, source enrichment and purification, radiopurity measurements.
