  The DAMA/LIBRA experiment is composed by about 250 kg of highly radiopure
NaI(Tl). It is in operation at the underground Gran Sasso National Laboratory
of the INFN. The main aim of the experiment is to investigate the Dark Matter
(DM) particles in the Galactic halo by exploiting the model independent DM
annual modulation signature. The DAMA/LIBRA experiment and the former DAMA/NaI
(the first generation experiment having an exposed mass of about 100 kg) have
released results corresponding to a total exposure of 1.17 ton $\times$ yr over
13 annual cycles; they have provided a model independent evidence of the
presence of DM particles in the galactic halo at 8.9 $\sigma$ C.L.. The results
of a further annual cycle, concluding the DAMA/LIBRA--phase1, have been
released after this Workshop and are not included here. In the fall 2010 an
important upgrade of the experiment have been performed. All the PMTs of the
NaI(Tl) detectors have been replaced with new ones having higher quantum
efficiency with the aim to decrease the software energy threshold considered in
the data analysis. The perspectives of the running DAMA/LIBRA--phase2 will be
shortly summarized.
