Abstract
AMS-02 is a precision particle physics experiment in space aiming to study dark matter, antimatter, and properties of cosmic rays to the TeV energy scale. This thesis presents a study of the cosmic ray positron fraction in AMS-02 data covering an energy range of 0.5 GeV to 500 GeV, and identifies 10.3 x 106 electron and 650 x 101 positron events. The results show that the positron fraction increases with energy and reaches a maximum at 275 ± 32 GeV.
