DAMA is an observatory for rare processes based on the development and use of various kinds of radiopure scintillators; it is operative deep underground at the Gran Sasso National Laboratory of the I.N.F.M. Several low background set-ups have been realized and many rare processes have been investigated. In particular, the DAMA/NaI set-up ( similar or equal to 100 kg highly radiopure NaI(T1)) has effectively investigated the model- independent annual modulation signature, obtaining from the data of seven annual cycles (total exposure of 107731 kg x day) a 6.3 sigma C.L. modelindependent evidence for the presence of a Dark Matter particle component in the galactic halo. Moreover, some of the many possible corollary model-dependent quests for the candidate particle have also been investigated. At present, the second generation DAMA/LIBRA set-up ( similar or equal to 250 kg highly radiopure NaI(T1)) is in operation deep underground.

Abstract
DAMA is an observatory for rare processes based on the development and use of various kinds of radiopure scintillators; it is operative deep underground at the Gran Sasso National Laboratory of the I.N.F.M. Several low background set-ups have been realized and many rare processes have been investigated. In particular, the DAMA/NaI set-up ( similar or equal to 100 kg highly radiopure NaI(T1)) has effectively investigated the model- independent annual modulation signature, obtaining from the data of seven annual cycles (total exposure of 107731 kg x day) a 6.3 sigma C.L. modelindependent evidence for the presence of a Dark Matter particle component in the galactic halo. Moreover, some of the many possible corollary model-dependent quests for the candidate particle have also been investigated. At present, the second generation DAMA/LIBRA set-up ( similar or equal to 250 kg highly radiopure NaI(T1)) is in operation deep underground.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
