Description

For more than 20 years the DAMA/LIBRA collaboration has reported a positive annual modulation in the low-energy detection rate of their NaI(Tl) detectors with very high C.L., that has been recently updated to 12.9$\sigma$. The interpretation of this result as a WIMP signal in standard models is, however, in strong tension with the null results of other experiments. Therefore there is an urge to verify the DAMA result independently, using the same target and technique.
This is the goal of the ANAIS experiment, in operation at the Canfranc Underground Laboratory with 112 kg of NaI(Tl) scintillators. After a commissioning period, the dark matter data taking started in August 2017. Here we present details of the detectors performance (light collection, low energy calibration, event selection, stability..) and a detailed background model. We will also discuss the physics potential of the experiment.
