- LIBRA abstract "The DAMA/LIBRA experiment is a particle detector experiment designed to detect dark matter using the direct detection approach, by using a scintilation detector to search for Weakly Interacting Massive Particles (WIMPs) in the galactic halo. The experiment aims to find an annual variation of the number of detection events, caused by the variation of the velocity of the detector relative to the dark matter halo as the Earth orbits the Sun. It is located at the Laboratori Nazionali del Gran Sasso in Italy.The detector is made of 25 highly radiopure scintillating thallium-doped sodium iodide (NaI(Tl)) crystals placed in a 5 by 5 matrix. Each crystal is coupled to two low background photomultipliers. The detectors are placed inside a sealed copper box flushed with highly pure nitrogen; to reduce the natural environmental background the copper box is surrounded by a low background multi-ton shield. In addition, 1 m of concrete, made from the Gran Sasso rock material, almost fully surrounds this passive shield. The installation has a 3-level sealing system which prevents environmental air reaching the detectors. The whole installation is air-conditioned and several operative parameters are continuously monitored and recorded.The DAMA/LIBRA data released so far correspond to 6 annual cycles. Considering these data together with those previously collected by DAMA/NaI over 7 annual cycles, the total exposure (1.17 ton x yr) has been collected over 13 annual cycles. This experiment has further confirmed the presence of model-independent evidence with high statistical significance on the basis of the dark matter signature.As previously done for DAMA/NaI, careful investigations on absence of any significant systematics or side reaction in DAMA/LIBRA have been quantitatively carried out.The obtained model independent evidence is compatible with a wide set of scenarios regarding the nature of the dark matter candidate and related astrophysical, nuclear and particle physics.DAMA/LIBRA was upgraded in 2008 and in 2010. In particular, the upgrade in 2010 allows an increase of the set-up’s sensitivity, the lowering of the energy threshold, and several other kinds of investigations.".
