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…
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…
Science with the new generation high energy gamma- ray experiments
M. Alvarez, D. D'Armiento, G. Agnetta +197
This Conference is the fifth of a series of Workshops on High Energy Gamma- ray Experiments, following the Conferences held in Perugia 2003, Bari 2004, Cividale del Friuli 2005, El…
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…
