Abstract

A measurement of the cosmic ray positron fraction e⁺ / (e⁺ + e^-) in the energy range of 1-30 GeV is presented. The measurement is based on data taken by the AMS-01 experiment during its 10 day Space Shuttle flight in June 1998. A proton background suppression on the order of 10⁶ is reached by identifying converted bremsstrahlung photons emitted from positrons.
