Integrated Design of Payload Based Dark Matter Particle Explorer

The Dark Matter Particle Explorer (DAMPE) is the first high energy detection satellite in China, and its scientific goal is to find the evidence of dark matter particle existence by investigating the composition and energy spectra of primary cosmic rays, especially for electrons, positrons and gamma rays, over the dynamic range from 5GeV to 10TeV. The DAMPE is composed by BGO calorimeter, plastic scintillation array detector, silicon array detector and neutron array detector, and is the largest payload ratio satellite. This paper introduces the technical schemes of DAMPE, including technical index, orbit, working mode and system composition, and the integrated design of structure, thermal control and EMC in DAMPE.
