High-energy cosmic ray proton spectrum

The method is describes and the results of measurements of the high-energy cosmic ray proton spectrum in the PAMELA experiment are presented. This experiment is performed onboard an artificial satellite and is directed to study cosmic ray particle spectra in a wide energy range. Scientific equipment was put into Earth orbit in June, 2006 and is in operation mode until now. The scientific equipment of the PAMELA device incorporates various detectors, including a magnetic spectrometer and a position-sensitive strip calorimeter. This study was performed based on the data of these devices. The energy range of the measured proton spectrum is from 50 GeV to 15 TeV. RI Cafagna, Francesco/A-9299-201
