Dark Matter Particle Explorer and Its First Results

摘要

The Dark Matter Particle Explorer (DAMPE) is China's first astronomical satellite dedicated to the indirect detection of dark matter particles and the study of high-energy astrophysics.It can measure high-energy electrons and gamma-rays up to 10 TeV with unprecedentedly high energy resolution and low background.Cosmic ray nuclei up to 100TeV can also be measured.DAMPE was launched on December 17,2015,and has been operating smoothly in space for more than two years since then.The first results about the precise measurements of the electron plus positron spectrum between 25 GeV and 4.6 TeV have been reported.
