AMS, A Particle Physics Experiment in Space

Abstract. The Alpha Magnetic Spectrometer, AMS, is a detector for charged and neutral particles, compact and light enough to be transported on a space craft. Its main physics goals are to detect antinuclei of cosmic origin in near Earth orbit, measure the composition and spectra of charged cosmic rays and photons up to TeV energies, and to search for dark matter signals.

After a successful pilot mission of a first version of the detector on NASA space shuttle Discovery in 1999, a more ambitious second version of the detector, AMS-02, is now being built. It is scheduled for installation on the International Space Station in October 2003, for a data taking period of at least three years. I will present the particle physics program of the AMS-02 project, review the expected performance of the detector and comment of the status of its construction.
