Resumen en inglés

The SuperNEMO experiment is looking for the neutrinoless double beta decay process (0 νβ β ) with a Tracker-Calorimeter technique. The aim of the experiment is to reach a sensitivity of 10 26 y equivalent to a Majorana effective mass of a 50-100 meV with ∼ 100 kg of enriched isotopes. A first module called Demonstrator is under construction at the Laboratoire Souterrain de Modane (LSM) at 4800 m.w.e. depth. It will host 7 kg of 82 Se isotope (Q β β =2.99 MeV) divided in thin foils of 40-60 mg/cm 2 thickness. The goal of this first phase is to reach a zero background level in the region of interest of 0 νβ β in order to demonstrate the feasibility of the full SuperNEMO experiment. The radiopurity strategies and the performances achieved are described as well as the status of the construction and integration of the Demonstrator module< Leer menos
