Description
A precise measurement of the proton flux in primary cosmic rays with
rigidity (momentum/charge) from 1 GV to 1.8 TV is presented based on 300
million events. Knowledge of the rigidity dependence of the proton flux
is important in understanding the origin, acceleration, and propagation
of cosmic rays. We present the detailed variation with rigidity of the
flux spectral index for the first time. The spectral index progressively
hardens at high rigidities.
