Description

The search of the annual modulation in the detection rates that could evidence the presence of galactic dark matter energy depositions in the detector is of utmost interest after DAMA/LIBRA positive result. Other experiment using the same target is required in order to confirm the effect, especially after the recent results from CDMS and CoGeNT. ANAIS is a project to be carried out at the Canfranc Underground Laboratory with such a goal, using about 250 kg of NaI(Tl) crystals to study the expected annual modulation in the galactic dark matter signal. A 9.6 kg NaI(Tl) crystal, is being tested underground. Background and noise rejection mechanisms thoroughly studied at the very low energies of interest. A low energy population of 40K internal background events at 3.2 keV has allowed to study such issues. ANAIS present status and prospects for the experiment will be also presented.
