Progress Report on the Measurement of the Carbon Flux in Cosmic Rays   from 1.9 GV to 2.6 TV with the Alpha Magnetic Spectrometer on the   International Space Station
  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.
