Abstract

The PAMELA experiment is a satelliteborne apparatus designed to study charged particles in the cosmic radiation, with a particular focus on antiparticles. The detector is housed on the Resurs-DK1 satellite and it is taking data since June 2006. The main parts of the apparatus are a magnetic spectrometer, which is equipped with a silicon-microstrip tracking system and which is used to measure the rigidity and the charge of particles, and a silicon/tungsten electromagnetic calorimeter which provides particle identification. The results of the analysis of the antiproton-to-proton flux ratio between 1 and 100 GeV which employs the data collected in 500 days is presented here. A total of about 1000 antiprotons have been identified, including 100 above an energy of 20 GeV.
