在核聚变堆及空间飞行器中,其关键部位的元器件、晶本受到高能粒子(中子、光子、电子、质子等)辐射是造成各种元器件失灵、失控乃至事故的主要原因。因此,计算各种材料的元器件的辐射损伤,对于材料的辐照筛选、设施的抗粒子辐射加固和安全运行有重要的意义。高能粒子辐射到晶体 In the nuclear fusion reactor and space vehicle, the key components of the nuclear reactor, radiation from the high-energy particles (neutron, photon, electron, proton, etc.) are the main causes of the failure of various components, out of control and even accidents. Therefore, the calculation of radiation damage of components of various materials is of great significance for the screening of materials, the anti-particle radiation reinforcement and the safe operation of the facilities. High-energy particles radiate to the crystal
