Reconstruction of Gamma Rays with AMS-02 — •Bastian Beischer — RWTH Aachen University, Aachen, Germany

AMS-02 is a high-precision multi-purpose particle detector mounted externally on the International Space Station (ISS). Although primarily designed for the measurement of charged cosmic rays, AMS-02 is able to precisely reconstruct photons in two complementary modes. Electrons from photon conversions in the upper part of the detector can be reconstructed due to the excellent tracking capabilities of the detector. In addition AMS-02 features a 17 radiation length electromagnetic calorimeter with a standalone trigger, which allows for a precise measurement of the properties of showers induced by gamma rays. The AMS-02 Tracker, TRD and Time-of-Flight systems provide a reliable veto for charged cosmic rays.

Techniques for the analysis of photons in AMS-02 will be discussed.
