Precision Measurement of the Proton Flux in Primary Cosmic Rays from Rigidity 1 GV to 1.8 TV with the Alpha Magnetic Spectrometer on the International Space Station

M. Aguilar, +294 more
TL;DR: In this paper, a precise measurement of the proton flux in primary cosmic rays with rigidity (momentum/charge) from 1.GV to 1.8TV is presented based on 300 million events.
Journal ArticleDOI

High Statistics Measurement of the Positron Fraction in Primary Cosmic Rays of 0.5-500 GeV with the Alpha Magnetic Spectrometer on the International Space Station

L. Accardo, +311 more
TL;DR: The new results show, for the first time, that above ∼200 GeV the positron fraction no longer exhibits an increase with energy.
Journal ArticleDOI

Precision Measurement of the Helium Flux in Primary Cosmic Rays of Rigidities 1.9 GV to 3 TV with the Alpha Magnetic Spectrometer on the International Space Station

M. Aguilar, +311 more
TL;DR: The detailed variation with rigidity of the helium flux spectral index is presented for the first time and the spectral index progressively hardens at rigidities larger than 100 GV.
Journal ArticleDOI

Electron and Positron Fluxes in Primary Cosmic Rays Measured with the Alpha Magnetic Spectrometer on the International Space Station

M. Aguilar, +279 more
TL;DR: In this paper, the Alpha Magnetic Spectrometer on the International Space Station was used to measure the primary cosmic-ray electron flux in the range 0.5 to 700 GeV and the positron flux in a range of 0.1 to 500 GeV.

High Statistics Measurement of the Positron Fraction in Primary Cosmic Rays of 0.5–500 GeV with the Alpha Magnetic Spectrometer on the International Space Station
