AMS Project at CIEMAT Highlights of space sensor developments in Spain 1st SPACERAD meeting in Brussels, 12 November 2002  The Astroparticle Physics Project at CIEMAT takes over the activities that few members of the HEP group started in 1997 through the participation in the precursor flight for the AMS Experiment Since year 2000, CIEMAT is participating in the Construction of the AMS-02 Detector æThe detector will have capabilities to identify the cosmic ray nuclei with Z  20 and to measure their energy spectrum up to the TeV region. æThe International Space Station (ISS) is a unique platform for accurate measurements of cosmic rays (low background, infrastructure capabilities) The purpose of the AMS Experiment is to perform accurate and high precision primary cosmic ray measurements in the space. A particle detector will be placed for a 3-year period on the International Space Station (ISS). AMS on the ISS Orbit altitude400 km Power 2 kW Weight~ 7 T Exposure time> 3 years
