Abstract

The results of the MC feasibility study of the AMS-02 Detector cosmic-ray γ and e+ spectra measurement capabilities are presented. AMS will be able to provide accurate measurements of the above spectra in a broad energy range (up to hundreds of GeV) with energy resolution of a few percent and angular resolution of 0.01-1°. The acceptance of 0.05-0.15 m2sr has been estimated both for e+ and γ, with maximal opening angle being 20° to 45°. The systematic study of the background events has been done, the irreducible background to signal ratio below a few percent being obtained.
