Abstract: CANDLES is the project to search for neutrino‐less double beta decay (0νββ) of 48Ca. The observation of 0νββ will prove existence of a massive Majorana neutrino. We have developed the new detector system CANDLES which features CaF2 (pure) scintillators. Here expected performances of the system for background rejection are presented. It is also described current status of development for the detector system.
