A method of identifying positron/electron species from the cosmic rays was studied in the DAMPE experiment. As there is no onboard magnet on the satellite, the different features imposed by the geomagnetic field on these two species were exploited for the particle identification. Application of this method to the simulation of on-orbit electrons/positrons/protons and the real flight data proves that separately measuring the CR positrons/electrons with DAMPE is feasible, though limited by the field of view for the present observation data. Further analysis on the positron flux with this method can be expected in the future.

“…The 12th generation of the model (IGRF-12) was adopted for this analysis. The model was finalized in 2014 December, providing a main field model for epoch 2015 and a predicted rate of change for 2015-2020(Thébault et al 2015.…”
