PAMELA sub-detectors capability in identifying nuclei: Status of art and perspectives

摘要

After almost three years in orbit, the statistic collected by PAMELA detector for what concern nuclei events from cosmic rays is sufficiently relevant to allow a systematic study of such a component. For this scope charge reconstruction from Time-of-Flight system, calorimeter and magnetic spectrometer is used, with different combinations, in order to cover the widest range of inspection in energy and atomic number permitted by the characteristics of the detector. Some results for performances, goals and limits from the different sub-detectors will be presented.
