On the 15th of June 2006, the PAMELA satellite-borne experiment was launched from the Baikonur cosmodrome and it has been collecting data since that time. The apparatus comprises a time-of-flight system, a magnetic spectrometer ( permanent magnet) with an silicon-microstrip tracking system, an imaging calorimeter built from layers of silicon -microstrip detectors interleaved with plates of...

The PAMELA experiment is collecting particles along a low Earth semi-polar orbit on board of Resurs-DK 1 satellite since June 2006. The combined information of a silicon tracking system and a scintillator hodoscope provides redundant light-element identification capabilities, via multiple ionization energy-loss measurements. Results on the abundances of galactic secondary elements Li and Be...

Lithium nuclei in cosmic rays are produced by the spallation of heavier cosmic rays on the interstellar medium. Thus, the abundance of Lithium constitutes a very sensitive observable for the modeling of cosmic rays propagation in the Galaxy. A precision measurement of the Lithium flux with rigidities from 2 GV to 3 TV by AMS, based on 1.6 million events, is presented for the first time. The...

A precision measurement by the Alpha Magnetic Spectrometer of the Boron to Carbon fluxes ratio with energies from 0.5 GeV/nucleon to 1 TeV/nucleon based on 10 million events is presented. Precision measurement of the Boron flux, based on 2 million events, together with the variation of the flux spectral index with rigidity is also presented.

A precision measurement of the flux ratio of Carbon to Helium in primary cosmic rays with rigidities from 2 GV to 2 TV is presented. Precision measurement of the Carbon flux, based on 8 million events, together with the variation of the flux spectral index with rigidity is also presented.

Voyager 1 (V1) has been in the local interstellar medium (LISM) since August, 2012. We present the galactic cosmic-ray (GCR) energy spectra of most elements from H through Ni, and also of electrons, for a period exceeding two years. The V1 energy spectra define the newly-revealed, low-energy part of the interstellar spectra of nuclei down to $\sim$1 MeV/nuc and of electrons down to $\sim$8...
