Abstract |
The ANAIS (Annual Modulation with NaI(Tl) Scintillators) experiment aims at the confirmation of the DAMA/LIBRA positive annual modulation signal using the same target and technique at the Canfranc Underground Laboratory. A first step, named ANAIS-25 (two 12.5 kg NaI(Tl) modules) and taking data from December 2012 to February 2015, provided interesting outcomes: very high light collection efficiency, that could allow to lower the analysis energy threshold down to the level of 1 keVee, and a good understanding of the different background components, in particular the cosmogenic activated isotopes in the crystal bulk and other radioactive contaminations of the NaI crystal/powder. But those prototypes clearly pointed to the need for improved crystal radiopurity, in particular for 210Pb contamination. Since then, important steps towards background reduction in the very low energy region have been given and a new 12.5 kg module has been constructed and installed between the former two crystals, forming the ANAIS-37 setup. Very preliminary results of this setup evidence the improvement on radiopurity of the new crystal and will be presented here. In addition, background simulations and prospects for the full experiment will be discussed. |
