“…However, the values measured by these experiments are inconsistent; efficiencies about 0.5 [2] and 0.2 [3,4] were reported. Furthermore, the existing data does not cover the energies below 40 keV, of utmost importance for WIMP search experiments.…”

“…• sensitivity to spin-independent (SI), spin-dependent (SD) and mixed (SI&SD) couplings as well as to several other existing scenarios 3 We take this occasion to remind that DAMA/NaI has been part of the DAMA project, which is also composed by several other low background set-ups, such as: i) DAMA/LXe (≃ 6.5 kg pure liquid Xenon scintillator) [24,25]; ii) DAMA/R&D, set-up devoted to tests on prototypes and small scale experiments [26]; iii) the new second generation large mass NaI(Tl) radiopure set-up DAMA/LIBRA (see later); iv) DAMA/Ge detector for sample measurements.…”

The DAMA/NaI experiment (≃ 100 kg highly radiopure NaI(Tl)) was proposed, designed and realised to effectively investigate in a model independent way the presence of a Dark Matter particle component in the galactic halo by exploiting the annual modulation signature. With a total exposure of 107731 kg · day, collected over seven annual cycles deep underground at the Gran Sasso National Laboratory of the I.N.F.N., it has pointed out -at 6.3 σ C.L. -an effect which satisfies all the peculiarities of the signature and neither systematic effects nor side reactions able to mimic the signature were found. Moreover, several (but still few with respect to the possibilities) corollary model dependent quests for the candidate particle have been carried out. In this paper the obtained results are summarized and some perspectives are discussed at some extent.

“…Effective and redundant background rejection schemes with a target mass in the 1000 kg range are perhaps the most attractive features of a LXe-based experiment for dark matter, with the additional advantage of being sensitive also to purely spin-dependent WIMP-nucleon interactions. Independent experimental programs using LXe in a variety of detector concepts are currently being pursued in Europe, Japan and the USA [6,7,8,9,10,11]. All these concepts make use of the excellent scintillation properties of LXe, which has the highest light yield among noble liquids, comparable with the best crystal scintillators.…”

Scintillation response of liquid xenon to low energy nuclear recoils

Liquid Xenon (LXe) is expected to be an excellent target and detector medium to search for dark matter in the form of Weakly Interacting Massive Particles (WIMPs). Knowledge of LXe ionization and scintillation response to low energy nuclear recoils expected from the scattering of WIMPs by Xe nuclei is important for determining the sensitivity of LXe direct detection experiments. Here we report on new measurements of the scintillation yield of Xe recoils with kinetic energy as low as 10 keV. The dependence of the scintillation yield on applied electric field was also measured in the range of 0 to 4 kV/cm. Results are in good agreement with recent theoretical predictions that take into account the effect of biexcitonic collisions in addition to the nuclear quenching effect.
