The Alpha Magnetic Spectrometer (AMS) on the international space station: Part II — Results from the first seven years / AMS Collaboration
The Alpha Magnetic Spectrometer (AMS) is a precision particle physics detector on the International Space Station (ISS) conducting a unique, long-duration mission of fundamental physics research in space. The physics objectives include the precise studies of the origin of dark matter, antimatter, and cosmic rays as well as the exploration of new phenomena. [...]

Properties of Neon, Magnesium, and Silicon Primary Cosmic Rays Results from the Alpha Magnetic Spectrometer / AMS Collaboration
We report the observation of new properties of primary cosmic rays, neon (Ne), magnesium (Mg), and silicon (Si), measured in the rigidity range 2.15 GV to 3.0 TV with $1.8×10^6$ Ne, $2.2×10^6$ Mg, and $1.6×10^6$ Si nuclei collected by the Alpha Magnetic Spectrometer experiment on the International Space Station. The Ne and Mg spectra have identical rigidity dependence above 3.65 GV. [...]

Towards Understanding the Origin of Cosmic-Ray Positrons / Aguilar, M (Madrid, CIEMAT) ; Ali Cavasonza, L (IAS, Julich ; JCHP, Julich) ; Ambrosi, G (INFN, Perugia) ; Arruda, L (LIP, Lisbon) ; Attig, N (IAS, Julich ; JCHP, Julich) ; Azzarello, P (Geneva U.) ; Bachlechner, A (IAS, Julich ; JCHP, Julich) ; Barao, F (LIP, Lisbon) ; Barrau, A (LPSC, Grenoble) ; Barrin, L (CERN) et al. /AMS
Precision measurements of cosmic ray positrons by the Alpha Magnetic Spectrometer on the International Space Station are presented up to 1 TeV based on 1.9 million positrons.The positron flux exhibits a significant excess starting from $25.2 \pm 1.8$ GeV followed by a sharp drop-off above $284^{+91}_{-64}$ GeV.In the entire energy range the positron flux is well described by the sum of a diffuse termassociated with low energy secondary positrons produced in the collision of cosmic rays, and a new source term of high energy positrons with a finite energy cutoff. The finite cutoff energy of the source term, $E_s$, is established with a significance of more than $4 \sigma$, and it's value is determined to be $E_s = 810^{+310}_{-180}$ GeV.These experimental data on cosmic ray positrons show that, at high energies, they predominantly originate either from dark matter collisions or from new astrophysical sources..
