Description

In 6 years on the Space Station, AMS has collected enormous amount of data up to multi-TV on both primary and secondary cosmic rays. Primary cosmic rays, such as p, He, C and O, are believed to be mainly produced and accelerated in supernova remnants, while secondary cosmic rays, such as Li, Be and B are thought to be produced by collisions of heavier nuclei with interstellar matter. By measuring all the nuclei simultaneously in the same detector with high statistics allow us to provide the detailed study of the energy dependence of all the fluxes with small systematic errors. The unique and distinct rigidity dependence of primary and secondary cosmic ray fluxes with charges Z=1 to Z=8 in the GV to TV rigidity range will be presented. The comparison of the AMS measurements with the predictions of the most recent cosmic ray propagation model GALPROP will also be discussed.
