Description
The ANAIS (Annual Modulation with NaI(Tl) Scintillators) experiment aims at the confirmation of the DAMA/LIBRA signal using the same target and technique at the Canfranc Underground Laboratory. 250 kg of ultrapure NaI(Tl) crystals will be used as a target, divided into 20 modules, each coupled to two photomultipliers. Two NaI(Tl) crystals of 12.5 kg each, grown by Alpha Spectra from a powder having a potassium level under the limit of the analytical techniques, form the ANAIS-25 set-up. A detailed study of ANAIS-25 background is underway, based on data taken in different configurations combined with Monte Carlo simulation, and its results will be presented. The bulk content in the crystals of potassium as well as of uranium and thorium radioactive chains has been quantifed and their cosmogenic activation evaluated. Finally, background simulations for the set-up with 250 kg will be shown and the status of the full ANAIS experiment will be reviewed.
