“悟空”玉宇探测暗物质——暗物质粒子探测卫星简介

Search for dark matter with Wukong,an introduction to the dark matter particle explorer

暗物质是当今科学研究的前沿热点研究领域。暗物质探测可以分为直接探测、间接探测和对撞机探测3类。其中间接探测是在宇宙线中寻找暗物质湮灭或者衰变产生的信号。2015年12月27号中国发射了第1颗用于暗物质粒子探测的空间科学卫星(DAMPE),它具有能量分辨率高、测量能量范围大和本底抑制能力强等优势,将中国的暗物质探测提升至新的水平。本文介绍暗物质粒子探测卫星的结构、性能优势和科学目标。

The study of dark matter is the current active subject of science research. There are three kinds of methods to detect dark matter particles which are direct detection, indirect detection and collider detection. The indirect detection of dark matter （DM） particles search the signals produced by DM annihilation or decay which are all kinds of excesses in the energy spectrum of CRs. The dark matter particle explorer （DAMPE） has already launched to space at December 27, 2015. It is the first science satellite in china and it has three advantages： large energy range, high energy revolution and strong background distinction. The mean scientific goals are dark matter indirect detection, cosmic ray physics and gamma ray astronomy. In this paper, we will introduce the structure of DAMPE, the advantage of DAMPE and the scientific goals of DAMPE.
