准直型空间X 射线望远镜本底研究概述OA北大核心CSCDCSTPCD

Because the detectors work in a terrible radiation environment outside the earth’s atmosphere, the background noises result in a low sensitivity of space telescope. The shield-ing modules of telescope play an important role in preventing the background noise, such as the collimators, anticoincidence detectors and so on. In addition, with the advance in com-puter programming capacity and the particle physics processes, method based on simulation makes a lot o…查看全部>>
