【摘要】 衍射辐射是由于运动的带电粒子遇到随空间变化的电介质而由感应电流产生的一种辐射．衍射辐射由于其非阻拦性,多参数性,可在线性,非常适合下一代对撞机和第四代光源的电子束诊断．简要介绍了其物理机制,系统的讨论了其在电子束诊断中的应用．更多还原

【Abstract】 Diffraction radiation is generated when there are optical inhomogeneities in the presence of which would cause induced currents that give rise to radiation. Diffraction radiation is the most promising candidate for beam characterizations for the 4th generation h’ght source and the next generation linear colliders due to its non-intercepting and multi-parameter features. In this paper, we gave a brief introduction to the principles of diffraction radiation and systematically studied its applications in electron beam diagnostics.更多还原
