The DAMA project at the Gran Sasso National Laboratories of the I.N.F.N. is an observatory for rare processes thanks to the development and use of large mass highly radiopure scintillator set-ups. The main activity field is the investigation on Dark Matter particles in the galactic halo and the search for several other rare processes (such as bb decay modes in various isotopes, charge-non-conserving processes, Pauli exclusion principle violating processes, nucleon instability, detection of solar axions and search for exotics).?
