Observation of an anomalous positron abundance in the cosmic radiation
O. Adriani, G. C. Barbarino, G. A. Bazilevskaya +48
Positrons are known to be produced in interactions between cosmic-ray nuclei and interstellar matter ("secondary production"). Positrons may, however, also be created by dark matte…
Two years of flight of the Pamela experiment: results and perspectives
M. Casolino, Pamela Collaboration
PAMELA is a satellite borne experiment designed to study with great accuracy cosmic rays of galactic, solar, and trapped nature in a wide energy range (protons: 80 MeV-700 GeV, ele…
Capability of the PAMELA Time-Of-Flight to identify light nuclei: results from a beam test calibration
D. Campana, R. Carbone, G. De Rosa +12
PAMELA is a space telescope orbiting around the Earth since June 2006. The scientific objectives addressed by the mission are the measurement of the antiprotons and positrons spect…
First Results from the PAMELA Space Mission
M. Boezio, V. Bonvicini, G. Jerse +53
On the 15th of June 2006, the PAMELA satellite-borne experiment was launched from the Baikonur cosmodrome and it has been collecting data since July 2006. The apparatus comprises a…
A new measurement of the antiproton-to-proton flux ratio up to 100 GeV in the cosmic radiation
O. Adriani, G. C. Barbarino, G. A. Bazilevskaya +50
A new measurement of the cosmic ray antiproton-to-proton flux ratio between 1 and 100 GeV is presented. The results were obtained with the PAMELA experiment, which was launched int…

PAMELA - A Payload for Antimatter Matter Exploration and Light-nuclei Astrophysics
P. Picozza, A. M. Galper, G. Castellini +57
The PAMELA experiment is a satellite-borne apparatus designed to study charged particles in the cosmic radiation with a particular focus on antiparticles. PAMELA is mounted on the…
The Cosmic-Ray Proton and Helium Spectra measured with the CAPRICE98 balloon experiment
M. Boezio, V. Bonvicini, P. Schiavon +36
A new measurement of the primary cosmic-ray proton and helium fluxes from 3 to 350 GeV was carried out by the balloon-borne CAPRICE experiment in 1998. This experimental setup comb…
Light Isotope Abundances in Solar Energetic Particles measured by the Space Instrument NINA
The NINA Collaboration, A. Bakaldin, A. Galper +34
This article reports nine Solar Energetic Particle events detected by the instrument NINA between October 1998 and April 1999. NINA is a silicon-based particle detector mounted on-…
