Abstract

The instrument PAMELA, in orbit since June 2006 on board the Russian satellite Resurs DK1, is designed to study charged particles, antiparticles and nuclei in the cosmic rays, with a particular focus on the search for antimatter and signals of dark matter, the isotopic composition and the investigation of phenomena connected with Solar and Earth physics. A combination of a magnetic spectrometer and different detectors allows antiparticles (antiprotons and positrons) to be reliably identified from a large background of other charged particles. New results on the antiprotonto- proton and positron-to-all electron ratios over a wide energy range (1-100 GeV) are presented, together with the measurement of the light nuclear component (from hydrogen to oxygen) of galactic cosmic rays in the range 100 MeV/n – 200 GeV/n.
