【摘要】：宇宙線的探測(cè)分為地面探測(cè)和空間探測(cè)。地面探測(cè)測(cè)量的是高能宇宙線(大于100 Te V)在大氣中產(chǎn)生的簇射的前鋒面。由于低能宇宙線在大氣中產(chǎn)生的簇射不能到達(dá)地面,所以要探測(cè)低能的宇宙線就需要把探測(cè)器送到大氣層外部。空間探測(cè)宇宙線的優(yōu)點(diǎn)是能測(cè)量低能宇宙線,并且能區(qū)分宇宙線的種類。暗物質(zhì)間接探測(cè)就是在宇宙線中尋找暗物質(zhì)湮滅或者衰變產(chǎn)生的信號(hào),表現(xiàn)在宇宙線能譜上就是各種超出。所以需要準(zhǔn)確區(qū)分宇宙線的種類,并且精確測(cè)量宇宙線的能譜。在文章中,作者將介紹宇宙線的相關(guān)理論以及空間探測(cè)暗物質(zhì)的研究現(xiàn)狀,并詳細(xì)介紹將于2015年底發(fā)射的暗物質(zhì)粒子探測(cè)衛(wèi)星,討論其在暗物質(zhì)間接探測(cè)方面的各種優(yōu)勢(shì)。
[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.
