'''ANAIS''' is a ] experiment designed to detect ]. ANAIS stands for ''Annual modulation with NAI ]s''. Its main goal is the direct detection of the dark matter through its ] off the target nuclei in a radiopure ] crystal. This dark matter signal should be annually modulated by the change in the relative velocity of ]-], a result of the rotation of the Earth around the Sun.

ANAIS is the scaled conclusion of feasibility studies carried out with different prototypes by the ] group at the ], Spain. The complete experiment will use more than one hundred of&nbsp;kg of ultrapure ]-] NaI(Tl) crystals. Data recording began at the end of October 2012 using 25&nbsp;kg in two prototype detectors as the last step before launching the larger experiment.<ref>, J.
