--- abstract: 'The Alpha Magnetic Spectrometer (AMS) is designed as an independent module for installation on the International Space Station (ISS) in the year 2003 for an operational period of three years. The principal scientific objectives include searches for antimatter and dark matter in cosmic rays. The AMS tracker uses silicon microstrip sensors to reconstruct charged-particle trajectories. A first version of the AMS, equipped with 2.1 m$^2$ of silicon sensors and a permanent magnet, was flown on the NASA space shuttle Discovery during June 2 - 12, 1998. The authors describe the detector and present results of the tracker performance during the flight.' adsnote: Provided by the SAO/NASA Astrophysics Data System adsurl: https://ui.adsabs.harvard.edu/abs/1999NCimA.112.1325A authors: - J.
