Capability of the PAMELA instrument to identify light-nuclei: results from a beam test calibration

PAMELA is a space telescope orbiting around the Earth since June 2006. The scientific objectives addresses by the mission are the measurement of the antiprotons and positrons spectra in cosmic rays, the hunt for anti-nuclei as well as the determination of light nuclei fluxes from hydrogen to oxygen in a wide energy range and with very high statistics. In this paper the charge discrimination capabilities of PAMELA for light nuclei, determined during a beam test calibration, will be presented.
