Abstract

The work is done within the framework of the PAMELA project [1]. The PAMELA is a space experiment for study of charged particles in the cosmic radiation that has been performed since the launch June 15 2006. This work is dedicated to the high energy cosmic ray proton and helium flux determination (an energy region from 50 GeV/nucleon) based on using a sampling electromagnetic calorimeter. The energy estimation was built on a measurement of a total deposited energy in the calorimeter and an applying of certain event selection criteria connected with an electromagnetic component of a hadronic shower. The helium-proton separation was performed by scintillation detectors of the PAMELA Time of Flight system. This method is indispensable to widen a measurable energy range and to receive additional information in the PAMELA experiment. The obtained energy spectra of protons and helium are presented.
