Status of the ANAIS Dark Matter Project at the Canfranc Underground Laboratory

Understand

The ANAIS experiment aims at the confirmation of the DAMA/LIBRA signal.

• A detailed analysis of two NaI(Tl) crystals of 12.5 kg each grown by Alpha Spectra will be shown: effective threshold at 1 keVee is at reach thanks to outstanding light collection and robust PMT noise filtering protocols and the measured background is well understood down to 3 keVee, having quantified K, U and Th content and cosmogenic activation in the crystals.
• A new detector was installed in Canfranc in March 2015 together with the two previous modules and preliminary characterization results will be presented.
• Finally, the status and expected sensitivity of the full experiment with 112 kg will be reviewed.
