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.

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.I documenti in FLORE sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
