Description
Deuterons are the most abundant of secondary cosmic rays and represent a few percent of the single-charged cosmic-ray nuclei. Cosmic-ray deuterons are expected to be produced by fragmentation of primary cosmic-ray Helium with the interstellar medium. Therefore, a good knowledge of the deuteron abundance and energy dependence provides essential information to verify and constrain cosmic-ray propagation models. Precision measurements of deuteron flux in the rigidity range from 2 to 20 GV as well as deuteron-to-proton flux ratio performed by the Alpha Magnetic Spectrometer during the first 8.5 years onboard the International Space Station will be presented.
