The AMS-02 (Alpha Magnetic Spectrometer) detector will operate on the International Space Station performing spectroscopy of cosmic rays searching for dark matter, trying to identify the products of the annihilation of WIMP candidates such as neutralinos.
The annihilation of a neutralino of a few hundred GeV mass could produce an excess in the 10-300 GeV region of the cosmic rays positron spectrum. With the joint use of a Transition Radiation Detector (TRD) and of an electromagnetic calorimeter, providing an overall 106 rejection factor for protons, AMS can detect a positron with a 90% efficiency.
The techniques used to achieve the physical and technological goals, together with the current status of the detector, will be discussed.
