以载荷为中心的暗物质探测卫星机电热一体化设计

暗物质粒子探测卫星是中国第一颗空间高能探测卫星，用于实现5GeV~10TeV大动态范围高能宇宙线（电子、正电子、伽马射线等）能谱测量.卫星有效载荷包括BGO量能器、硅阵列探测器、塑闪阵列探测器和中子探测器，是目前中国发射的载荷比最大的卫星.本文介绍了卫星相关技术方案，包括技术指标、轨道方案、工作模式及系统组成等，突出了其以载荷为中心的机电热一体化设计特点. 

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.
