Description
We report the latest results on the properties of C, N, Ne, Na,Mg, Al, S, Cl, Ar, K, and Ca cosmic rays fluxes in the rigidity range 2.5 GV to 3 TV collected by the AMS furing first 13.5 years of operation. We observe that fluxes are well described by the sums of a primary cosmic ray component and a secondary cosmic ray component. With our measurements, the abundance ratios at the source C/O, N/O, Ne/Si, Na/Si, Mg/Si, Al/Si, S/Si, Cl/Si, Ar/Si, K/Si, and Ca/Si are determined independent of cosmic ray propagation.
