Abstract

PAMELA cosmic-ray detector is orbiting around the Earth on board the Resurs DK1 satellite since June 2006. The experiment is designed to study charged particles in the cosmic radiation, being optimized in particular for antiprotons and positrons. The core of the detector is a spectrometer composed of six planes of silicon microstrip sensors, which are placed inside the magnetic cavity of a permanent magnet. The apparatus is used to reconstruct the trajectory of cosmic rays which cross the cavity, and to measure their momentum and charge. In this paper the main features of the spectrometer are reviewed and its performances in flight are shown.
