Abstract

The PAMELA experiment is a satellitebased apparatus launched in June 2006. Its core instrument is a magnetic spectrometer, whose high spatial resolution (∼ 3 micron) provides the discriminative power to separate particles and antiparticles. It can measure the momentum and the energy-loss rate of an incident particles, thus allowing to identify higher charges (up to Z ≃ 5). The main goal for PAMELA is a precise measurement of the light antimatter component in cosmic rays (antiprotons, positrons), with unprecedented statistics and over a largely unexplored energy range. The instrument characteristics and the large statistics allow to precisely measure absolute fluxes for various cosmic-ray species up to high energy. Here the He flux analysis above some GeV is presented.
