Abstract

The AMS-02 was installed on the International Space Station (ISS) in May 2011 and has since then been successfully collecting data. One of its main sub-detectors, the silicon tracker, determines the rigidity, charge sign and absolute charge of cosmic rays by up to nine layers, which give the maximum lever arm of 3 m. For the best performance of the tracker the relative position of nine layers has to be known with a precision better than 10 µm at any moment. In this contribution the procedure and the evaluation of the accuracy of the alignment are discussed.
