Abstract: The main aim of the 100 kg highly radiopure NaI(Tl) set-up of the DAMA project (DAMA/NaI) has been the exploitation of the model independent WIMP annual modulation signature.The total exposure (107731 kg × day), collected during seven annual cycles, has given a model independent evidence for the presence of a Dark Matter particle component in the galactic halo at 6.3 σ C.L.; this main result is summarised here.Some of the many possible corollary model dependent quests for the candidate particle are also mentioned.At present, after about five years of new developments, a second generation low background set-up (DAMA/LIBRA with a mass of 250 kg NaI(Tl)) was built and is taking data since March 2003.New R&D efforts toward a possible NaI(Tl) ton set-up, we proposed in 1996, have been funded and started in 2003.
