THE PAMELA EXPERIMENT: A CLUE TO THE ENIGMA OF ANTIMATTER IN SPACE
PAMELA is a satellite-borne experiment whose main physics goals are the search for cosmic antimatter of primary origin and the measurement of the spectrum of cosmic ray particles and antiparticles in the energy range from ~50 Mev to 200 GeV and beyond.
Additional objectives are the continuous monitoring of the cosmic ray solar modulation, the study of the solar flares and the stationary perturbed fluxes in the Earth magnetosphere.
The PAMELA apparatus will fly in a low polar sun-synchronous orbit for at least three years. It consists of a magnetic spectrometer with a particle identification system.
The scientific objectives, the mission profile and a general description of the instrument are presented.
