“…Glass pellets (lead-free glass) of (2.1±0.1) mm in diameter were analyzed by 6 SuperNEMO laboratories, as well as by 7 external expert laboratories. Detail information on the intercomparison exercise and on the certification process is described elsewhere [17]. This reference material may be used for quality management of analytical laboratories, assessing the validity of analytical methods and identifying weaknesses in methodologies.…”

The SuperNEMO experiment is a new generation of experiments dedicated to the search for neutrinoless double beta-decay, which if observed, would confirm the existence of physics beyond the Standard Model. It is based on the tracking and calorimetry techniques, which allow the reconstruction of the final state topology, including timing and kinematics of the double beta-decay transition events, offering a powerful tool for background rejection. While the basic detection strategy of the SuperNEMO detector remains the same as of the NEMO-3 detector, a number of improvements were accomplished for each of detector main components. Upgrades of the detector technologies and development of low-level counting techniques ensure radiopurity control of construction parts of the SuperNEMO detector. A reference material made of glass pellets has been developed to assure quality management and quality control of radiopurity measurements. The first module of the SuperNEMO detector (Demonstrator) is currently under construction in the Modane underground laboratory. No background event is expected in the neutrinoless double beta-decay region in 2.5 years of its operation using 7 kg of 82 Se. The half-life sensitivity of the Demonstrator is expected to be > 6.5•10 24 y, corresponding to an effective Majorana neutrino mass sensitivity of |0.2 − 0.4| eV (90 % C.L.). The full SuperNEMO experiment comprising of 20 modules with 100 kg of 82 Se source should reach an effective Majorana neutrino mass sensitivity of |0.04 − 0.1| eV, and a half-life limit 1•10 26 y.
