Measurment of the cosmic ray electron and positron flux with AMS02 — •Yasaman Najafijozani — Gebäude: 4280 Raum28B203 Sammelbau Physik, Sommerfeldstr. 14, Turm 28 52074 Aachen

The Alpha Magnetic Spectrometer (AMS-02) on the International Space Station has been performing precision measurements of cosmic rays in the GeV to TeV energy range since 2011. The fluxes of electrons and positrons are potential probes of dark matter or new astrophysical phenomena. With AMS-02, electrons and positrons are identified by two independent subdetectors, a transition radiation detector and an electromagnetic calorimeter. I will present my cosmic-ray electron and positron flux analysis from 0.5 to 1000 GeV.
