Die weltraumqualifizierte Datenakquisition des Übergangsstrahlungsdetektors im AMS-02 Experiment auf der Internationalen Raumstation. The Space Qualified Data Acquisition for the Transition Radiation Detector of the AMS-02 Experiment on the International Space Station

The transition radiation detector (TRD) of the Alpha Magnetic Spectrometer (AMS-02) for cosmic rays allows a separation of positrons and protons and will be operated on the International Space Station for three years. Its space qualified readout electronics, developed and operated under responsibility of University of Karlsruhe, and the TRD front end have shown an excellent performance with cosmic rays on the ground in 2008. The readout system and the results of the first data are discussed.
