Description
The Alpha Magnetic Spectrometer (AMS-02) with its acceptance of about 0.45 m^2 sr, is the largest Solar Energetic Particle (SEP) detector in space. It was installed on the International Space Station (ISS) on May 19, 2011, where it will take data for the duration of the station (≈ 2024). In the first 3 years of operations, AMS-02 detected and measured the highest energy SEPs produced during M- and X-class flares and fast coronal mass ejections magnetically connected with the Earth. AMS-02 is able to perform precise measurements in a short period of time which is typical of these transient phenomena and to collect enough statistics to measure fine structures and time evolution of the spectrum. The method to identify the SEPs over the galactic cosmic rays background will be described. The events observed by AMS-02 since the beginning of its mission will be presented and some SEP preliminary results will be shown. AMS-02 observations, with their unprece- dented resolution and high statistics, can therefore help to understand the behavior of SEPs at high energies and to constrain models of SEP production.
