【 摘 要 】

The Alpha Magnetic Spectrometer (AMS-02) is a large acceptance particle physics detector installed on board the International Space Station (ISS) since May 19th 2011 to search for primordial anti-matter, for indirect signals of dark matter and to perform a high statistic and long duration measurement of the spectra of primary charged cosmic rays. Precise measurements of the electron and positron fluxes and of the total e++e-flux are presented. These AMS results provide a deeper understanding of the nature of high energy cosmic rays and can shed more light on the nature of dark matter.
