description The Alpha Magnetic Spectrometer, AMS, is successfully operating on the International Space Station for more than 6 years and has collected over 100 billion cosmic rays. One of the main objectives of AMS is to search for Dark Matter through the precision measurements of charged elementary particles in the cosmos. The positron flux is measured in the energy range of 0.5 to 700 GeV and electron flux of 0.5 to 1000 GeV. Both positron and electron fluxes require additional sources of high energy positrons and electrons, like the Dark Matter. The antiproton flux is measured in the absolute rigidity(momentum/charge) of 1 to 450 GV. The antiproton to proton flux ratio is rigidity independent above 60 GV. In the absolute rigidity range of ∼60 to ∼500 GV, the positron, antiproton and proton fluxes have nearly identical rigidity dependence. These are new observations of the properties of charged elementary particles in the cosmos.
