THE AMS SILICON MICROSTRIPS TRACKER

摘要

The Alpha Magnetic Spectrometer is a detector designed to search for anti-matter and dark matter by the analysis of cosmic rays in space. Its installation is scheduled on the International Space Station (ISS) for an operational period of 3 years. A precursor flight on a Space Shuttle occured in 1998 with a silicon surface of 2.1 m~2. The construction of the 7 m~2 second phase is starting. The AMS silicon tracker has a large dynamic range of up to 100 MIPS for dE/dx measurement. We discuss the design, construction and performance of the detector.
