The internal alignment and position resolution of the AMS-02 silicon tracker determined with cosmic-ray muons

The Alpha Magnetic Spectrometer is a large acceptance cosmic-ray detector (0.5m2sr) designed to operate at an altitude of 400 km on the International Space Station. The AMS-02 silicon tracker contains 2264 silicon microstrip sensors (total active area 6.75m2). The internal alignment parameters of the assembled tracker have been determined on the ground with cosmic-ray muons. The alignment procedure is described and results for the alignment precision and position resolution are reported.
