  The present status of the ANAIS experiment (Annual Modulation with NaI's) is
shown. ANAIS is intended to use more than 100 kg of NaI(Tl) in the Canfranc
Underground Laboratory (Spain) searching for seasonal modulation effects in the
WIMP signal; in a first stage, a prototype (one single 10.7 kg crystal) has
been developed in order to obtain the best conditions regarding the energy
threshold and the radioactive background in the low energy region as well as to
check the stability of the environmental conditions. The first results
corresponding to an exposure of 2069.85 kg day show an average background level
of 1.2 counts/(keV kg day) from threshold ($E_{thr} \sim 4$ keV, even using one
single photomultiplier) up to 10 keV.
