【摘要】：宇宙线的探测分为地面探测和空间探测。地面探测测量的是高能宇宙线(大于100 Te V)在大气中产生的簇射的前锋面。由于低能宇宙线在大气中产生的簇射不能到达地面,所以要探测低能的宇宙线就需要把探测器送到大气层外部。空间探测宇宙线的优点是能测量低能宇宙线,并且能区分宇宙线的种类。暗物质间接探测就是在宇宙线中寻找暗物质湮灭或者衰变产生的信号,表现在宇宙线能谱上就是各种超出。所以需要准确区分宇宙线的种类,并且精确测量宇宙线的能谱。在文章中,作者将介绍宇宙线的相关理论以及空间探测暗物质的研究现状,并详细介绍将于2015年底发射的暗物质粒子探测卫星,讨论其在暗物质间接探测方面的各种优势。
[Abstract]:Cosmic ray detection is divided into ground detection and space detection. Ground detection measures high energy cosmic rays (> 100Te V). The front surface of a shower in the atmosphere. A shower produced in the atmosphere by low-energy cosmic rays cannot reach the surface. Therefore, to detect low-energy cosmic rays, we need to send the detectors out of the atmosphere. The advantage of space exploration cosmic rays is that they can be measured. Indirect detection of dark matter is the search for signals produced by the annihilation or decay of dark matter in cosmic rays. In the cosmic ray spectrum is a variety of excesses. Therefore, it is necessary to accurately distinguish the types of cosmic rays, and accurately measure the energy spectrum of cosmic rays. In this article. The author will introduce the related theory of cosmic ray and the research status of space detection dark matter, and introduce in detail the dark matter particle detection satellite which will be launched on end of 2015. Its advantages in indirect detection of dark matter are discussed.
