Contribution

It presents the first detailed measurement of the cosmic ray carbon flux from 1.9 GV to 2.6 TV using AMS data collected over five years.

Findings

Carbon flux measured over 8.3 million events

Rigidity dependence analyzed from 1.9 GV to 2.6 TV

Implications for cosmic ray origin and acceleration

Abstract

Knowledge of the precise rigidity dependence of the carbon flux is important in understanding the origin, acceleration and propagation of cosmic rays. The current status of the measurement of the carbon flux in cosmic rays with rigidity from 1.9 GV to 2.6 TV, based on 8.3 million events collected by the Alpha Magnetic Spectrometer during the first 5 years of operation, is presented.
