摘要：The Alpha Magnetic Spectrometer (AMS) is a particle spectrometer on board of the International Space Station. It measures the charge, energy and momentum of charged cosmic rays with unprecedented precisions from 1GV to a few TV in rigidity. AMS has collected and analyzed more than 160 billion cosmic ray events during 6 years of operation since May 2011. In this talk we report the latest AMS measurements of the cosmic ray spectra of electron, positron, proton, antiproton, and light nuclei, including He, Li, Be, B, and C, O. These data provide important new inputs for the study of fundamental physics as well as probing the universe with charged cosmic rays.
