1. Goal of the experiment

The goal of the researches is to study the cosmic ray composition in a wide range of energies (from few tens of MeV up to some hundreds of GeV), with particular attention to the antimatter component: positrons, antiprotons and the search for anti-nuclei with a sensitivity on the anti-helium/helium ratio better than 10-8.
