Measurement of spectra of Carbon and Oxygen nuclei of cosmic rays with the Dark Matter Particle Explorer
Abstract
The DArk Matter Particle Explorer (DAMPE) is a space high-energy cosmic ray and gamma-ray detector launched on December 17, 2015. Its main scientific goals include the indirect detection of dark matter particles and the exploration of cosmic ray physics. The DAMPE comprises four sub-detectors, the Plastic Scintillator Detector (PSD) used for charge reconstruction, the Silicon-Tungsten tracKer-converter (STK) for track measurement, the BGO colorimeter (BGO) for energy measurement and electron-hadron discrimination, and the NeUtron Detector (NUD) for additional electron-hadron discrimination. In this contribution, the analysis and preliminary results about the energy spectra of Carbon and Oxygen nuclei are presented. Both the Carbon and Oxygen spectra show hardening behaviors at several hundred GeV/n energies which are consistent with previous measurements.
