A measurement of the cosmic ray positron fraction $e^{+}/(e^{+}+e^{−})$ in the energy range of 1–30 GeV is presented. The measurement is based on data taken by the AMS-01 experiment during its 10 day Space Shuttle flight in June 1998. A proton background suppression on the order of 10$^{6}$ is reached by identifying converted bremsstrahlung photons emitted from positrons.

• Dark matter annihilations and decays after the AMS-02 positron measurements (2013, methodology): “In the last few years, data of extraordinary quality on the positron flux or fraction has been collected by several experiments, notably CAPRICE [1], HEAT [2], AMS01 [3], PAMELA [4, 5] and AMS-02 [6, 7].”
• Galactic secondary positron flux at the Earth (2008, background): “For instance, the AMS electron data points of Aguilar et al. (2007) and Alcaraz et al. (2000), which are known to be among the most precise data sets to date, reach∼ 30 GeV only.”
• Cosmic ray transport in the Galaxy: A review (2017, result): “The first surprising finding was the unequivocal detection by PAMELA (Adriani et al., 2009) of a growing positron fraction (e+/(e− + e+)), following earlier, but statistically less significant claims by CAPRICE (Boezio et al., 2001), HEAT (Beatty et al., 2004) and AMS-01(Aguilar et al., 2007).”
