The Alpha Magnetic Spectrometer (AMS), installed on the International Space Station will provide precise measurements of the cosmic ray spectra in the GeV to TeV energy range, and will search for cosmological antimatter
and dark matter. A first version of the detector was operated successfully during a precursor flight on the space shuttle
Discovery in June 1998 (STS-91). The magnetic spectrometer uses a large area (7.2 m2) silicon microstrip detector
providing 10um spatial resolution for the bending coordinate. Here we briefly report on the design of the AMS tracker,
its construction status and some innovative assembly techniques we have developed.
