Description
SuperNEMO takes advantage of the tracking calorimetry technique successfully launched by NEMO3. This technique reduces the backgrounds and allows for excellent discrimination of different $0\nu\beta\beta$ mechanisms. SuperNEMO can simultaneously observe different double beta emitters, $^{48}$Ca, $^{82}$Se and $^{150}$Nd are currently under consideration. The demonstrator will employ 7~kg of enriched $^{82}$Se shaped in thin foil installed in the center of the detector. The R&D for new techniques of foil fabrication will be described, focusing on materials choice and background reduction at the level of 2~$\mu$Bq/kg and 10~$\mu$Bq/kg for $^{208}$Tl and $^{214}$Bi respectively. New developments with innovative purification methods will also be discussed with the aim of comparing the radio-purities at a later stage.
