The Alpha Magnetic Spectrometer is a large acceptance instrument conceived for the search of primordial anti-matter and dark matter on board the International Space Station (ISS) orbiting at 400 km from the earth surface. Nine layers of double sided silicon microstrip detectors track with a single point resolution of 10 μm the charged particle trajectories bent in the magnetic field of a permanent magnet. Redundant measurements of the charge magnitude, velocity, momentum and energy of the cosmic rays are performed by the different detectors integrated in AMS-02. The large acceptance and a long exposure time, matching the ISS operational lifetime, will allow AMS-02 to collect a wealth of data to study with unprecedented accuracy the composition and the energy spectrum of charged CRs and gammas up to the TeV energy scale. Launched with the STS-134 mission of the Shuttle Endeavour on May 16th 2011, AMS-02 has been installed on May 19th on the ISS and it is continuously taking data since then. In this contribution we will revue the characteristics of the instrument and report on the AMS-02 status in orbit.

Abstract
The Alpha Magnetic Spectrometer is a large acceptance instrument conceived for the search of primordial anti-matter and dark matter on board the International Space Station (ISS) orbiting at 400 km from the earth surface. Nine layers of double sided silicon microstrip detectors track with a single point resolution of 10 μm the charged particle trajectories bent in the magnetic field of a permanent magnet. Redundant measurements of the charge magnitude, velocity, momentum and energy of the cosmic rays are performed by the different detectors integrated in AMS-02. The large acceptance and a long exposure time, matching the ISS operational lifetime, will allow AMS-02 to collect a wealth of data to study with unprecedented accuracy the composition and the energy spectrum of charged CRs and gammas up to the TeV energy scale. Launched with the STS-134 mission of the Shuttle Endeavour on May 16th 2011, AMS-02 has been installed on May 19th on the ISS and it is continuously taking data since then. In this contribution we will revue the characteristics of the instrument and report on the AMS-02 status in orbit.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
