暗物质粒子探测卫星(DAMPE)已于2015年12月17日成功发射，目前进入了正常科学观测模式阶段。DAMPE的高能伽玛射线探测不仅可以用于高能天体物理研究，还可用于暗物质间接探测。由于宇宙线中90%以上是质子，而高能伽玛射线的流量比质子低5-6个数量级。因此如何从大量的宇宙射线本底中高效、可靠的挑选出高能伽玛射线对于DAMPE这样的高能粒子探测器是一个具有挑战性的课题。本项目就是以高效的从海量本底中选择出高能伽玛射线为研究目标，研究高能伽玛射线和宇宙线本底与探测器作用的差别并进而获得高时间、高空间、高能量分辨的伽玛射线天文观测成果。

DArk Matter Particle Explorer(DAMPE)was successfully launched on December 17,2015. Now it continually detect the cosmic rays and gamma-rays. The high energy gamma-ray data is not only helpful for the high energy astrophysics but also fo rthe dark matter indirect detection. However, the cosmic rays are more than the gamma-rays by 5-6 orders of magnitude and it is very challenging to separate the gamma-rays from the cosmic rays. We aim to develop an efficient method in which the gamma-rays can be reliably distinguished from the cosmic rays, with which we can get the high time, high spatial and high energy resolution gamma-ray data.
