The DAMA/NaI experiment investigated the presence of dark matter particles in the galactic halo by exploiting the model-independent annual modulation signature. Based on the Earth's orbit around the Sun and the Solar System's speed with respect to the center of the galaxy (which on short time scales can be considered constant), the Earth should be exposed to a higher flux of dark matter particles around June 1, when its orbital speed is added to that of the Solar System with respect to the galaxy and to a smaller one around December 2, when the two velocities are subtracted.

The DAMA/NaI experiment investigated the presence of dark matter particles in the galactic halo by exploiting the model-independent annual modulation signature. Based on the Earth's orbit around the Sun and the Solar System's speed with respect to the center of the galaxy (which on short time scales can be considered constant), the Earth should be exposed to a higher flux of dark matter particles around June 1, when its orbital speed is added to that of the Solar System with respect to the galaxy and to a smaller one around December 2, when the two velocities are subtracted. The annual modulation signature is distinctive since the effect induced by dark matter particles must simultaneously satisfy many requirements.
==Description== The experimental set-up was located deep underground in the Laboratori Nazionali del Gran Sasso in Italy.
