Cosmic Ray Space Experiments
arXiv:2502.18025
Abstract
This article describes experiments in space which measure charged cosmic ray particles in the range from to of magnetic rigidity . In this energy range, cosmic rays are expected to originate from sources in the Milky Way and be confined to our galaxy. Spectra of nuclei and their chemical composition are discussed. The spectrum of antiprotons and the search for heavier anti-nuclei are covered. All spectra and especially those of electrons and positrons are analysed for indications of unconventional particle sources, acceleration or transport mechanisms.
