Description
The PAMELA satellite-borne experiment was launched from the Bajkonur cosmodrome in June 2006. The combination of a permanent magnet silicon strip spectrometer and a silicon-tungsten imaging calorimeter allows precision studies of the charged cosmic rays to be conducted over a wide energy range with high statistics.
After five years of successfully operation in space, the data gathered by the PAMELA experiment are showing very interesting features in cosmic rays spectra, namely in the fluxes of protons, heliums and electrons, that may challenge the current paradigm of cosmic-ray acceleration and propagation in the Galaxy. In addition, PAMELA measurements of cosmic antiproton and positron fluxes are setting strong constraints to the nature of Dark Matter.
This talk illustrates the most recent scientific results obtained by the PAMELA experiment.
