Description

Direct measurements of cosmic-rays (CRs) is fundamental to achieve a better understanding of their origin, mechanism of acceleration and propagation in the Galaxy. Due to the hardening around a few hundred GeV/n in the spectrum of proton, helium and heavy nuclei from recent observations, it is of great importance to provide new and precise measurements of the region of transition for each nuclear species up to the TeV scale. The space experiment of DArk Matter Particle Explorer (DAMPE) is designed to measure CRs and gamma-rays in space, and since December 2015, it is collecting data with smooth and continuous operations. DAMPE has good potential to distinguish the elemental composition of CRs and measures CRs in the energy range of 50 GeV to 100 TeV. In this report, the selection criteria of the carbon and oxygen component will be presented; efficiency of event selections will be validated by Monte Carlo simulations and analysis of system error will be also demonstrated in this report.
