Description
The cosmic-ray(CR) electrons and positrons are of great significance for studying the origin and propagation of cosmic-rays. The satellite-borne experiment DArk Matter Particle Explorer(DAMPE) has been used to measure the separate electron and positron spectra, as well as the positron fraction. In this work, the Earth's magnetic field is used to distinguish CR electrons and positrons, as the DAMPE detector does not carry an onboard magnet. Considering the pointing and acceptance of DAMPE on orbit, the energy range for the measurements introduced in this work is 10 to 20 GeV. The results are consistent with the previous measurements based on magnetic spectrometer, like AMS-02.
