摘要

摘要: 基于电子储存环的同步辐射具有稳定性高、光子能量范围广、支持多用户等优势，但其辐射相干性较差。在储存环上实现相干辐射不但可以大幅提高辐射光的相干性，同时还可以极大地提高特定频谱范围内的光通量、亮度和能量分辨率。随着光通量的提高，其功率有可能达到工业应用的水平，这将拓展光源的应用范围。回顾了基于电子束储存环的各类相干光源的发展历史，并展望其发展趋势。

Abstract: Synchrotron radiation from an electron storage ring holds many advantages such as stability, broad spectrum, multi-users supporting. However, it lacks coherence. When the coherent radiation is produced from a storage ring, not only the coherence of the light is enhanced, but also the flux, brightness and the energy resolution of the light can be remarkably improved. As the flux is further increased, the power of the radiation may reach the requirement of industry. This paper presents a review of various kinds of electron storage ring based coherent light sources and gives an outlook of its development.
