Abstract

AMS-02 is a wide acceptance high-energy physics experiment installed on the International Space Station in May 2011 and operating continuously since then. Using the largest number of detected particles in space of any space-borne experiment, it performs precision measurements of galactic cosmic rays fluxes. Detailed time variation studies of Protons, Heliums, Electron and Positron fluxes were presented. The low-rigidity range exhibits a decreasing general trend strongly related to the increase of solar activity, as well local decreases associated with strong solar events.
