The DAMPE (DArk Matter Particle Explorer), one of the five satellite missions in the framework of the Strategic Pioneer Research Program in Space Science of the Chinese Academy of Science (CAS), was successfully launched on December 17 last year. DAMPE is a powerful space telescope which has as main scientific objective the identification of possible Dark Matter signatures thanks to the capability to detect electrons and photons in a wide range of energy from 5 GeV up to 10 TeV and with unprecedented energy resolution. Moreover, the DAMPE satellite will contribute to a better understanding of the origin and propagation mechanisms of high energy cosmic rays thanks to the measurement of the flux of nuclei up to 100 TeV. Hints in the sector of high energy gamma astronomy are also expected thanks to its excellent photon detection capability. After the launch DAMPE has shown excellent performance in orbit. Currently, data is being analyzed and the first results will be published soon. Here we present a detailed description of the DAMPE tracker: the Silicon-Tungsten tracKer-converter (STK). The STK was developed by an international collaboration composed of groups from University of Geneva, INFN Perugia, INFN Bari, INFN Lecce and Institute of High Energy Physics in Beijing. The STK is made of 192 ladders of about 10 cm by 40 cm, each of them is made up of four single-sided silicon strip detectors. We will report the performance of the silicon ladders in proton and ions beams during several test beam periods at the CERN SPS (Super Proton Synchrotron) in 2015.
