由于固体径迹探测器对重电离粒子灵敏、分辨率好、成本低、重量轻,不要电源易于大面积运载到高空,所以在宇宙线研究中得到了广泛的应用。特别是在寻找稀少的新粒子,如磁单极子方面显示了优越性。但是它没有时间分辨的本领。有时需要和其他探测器配合使用。我们主要在以下几方面应用。 As the solid track detector is sensitive to heavy ionization particles, it has good resolution, low cost and light weight. It is not necessary for the power source to be easily transported over a large area to the sky. Therefore, it has been widely used in cosmic ray research. Especially in the search for rare new particles, such as magnetic monopole shows the superiority. But it does not have the time to tell. Sometimes need to use with other detectors. We mainly apply in the following aspects.
