AMS (the Alpha Magnetic Spectrometer) is a high-energy particle detector in space. An engineer- ing version of AMS, AMS-01, flew on the space shuttle Discovery for ten days in June 1998 and collected 108 cosmic ray events. This thesis extends the previous results of the AMS-01 flight by performing a search for antideuterons (−D) in cosmic rays. Antideuterons in cosmic rays could be a signal for neutralino dark matter annihilation, primordial black hole evaporation and other interesting processes. No D̄ nuclei were found, and a flux limit is estimated. We also present the results of preliminary strangelet search. Some interesting effects of the Mir space station on AMS-01 when Discovery was docked with Mir are also discussed.
Parmi les événements observés, une trentaine sont compatibles avec les photons de haute énergie qui produisent une conversion dans la partie supérieure du détecteur.
