Abstract
The Alpha Magnetic Spectrometer (AMS-02) is a multipurpose astroparticle physics detector installed since May 2011 as an external module on the International Space Station (ISS). AMS-02 orbits at an altitude of about 430km for measuring with an unprecedented accuracy the flux and composition of primary cosmic rays in the GeV-TeV energy range, searching for primordial Anti-Matter and probing the nature of Dark Matter. Despite the fact that AMS-02 is designed primarly as a charged-particle detector, it is also an instrument able to perform precision observations of γ-rays. The key sub-detector in the photon identification and reconstruction is the e.m. calorimeter that, besides having an excellent energy resolution, can also provide the direction of the incoming particle. In this paper the AMS-02 γ-rays sky obtained with the first 22 months of data is presented.
