  • 摘要: X射线自由电子激光是一种基于电子直线加速器的大型科学研究装置,可以产生超高亮度、超短脉冲、波长可调的相干X射线辐射,在物理、化学、材料、生命科学等诸多领域都有非常广泛和极为重要的应用。文章介绍了X射线自由电子激光的基本原理、运行模式、发展历程、国内外X射线自由电子激光大科学装置的发展态势以及近年来我国X射线自由电子激光装置的现状。

     

    Abstract: X-ray free electron lasers (FELs) are large-scale scientific facilities that hold great promise for the generation of coherent short-wavelength radiation with ultra-high brightness and ultra-short pulse duration. They enable unprecedented exploration of physics, chemistry, material science, biology, and so forth, with spatial and temporal resolution down to the atomic and molecular level. This article gives an overview of the basic principle, historical development, current operation modes, and state-of-the-art of X-ray FEL facilities throughout the world, as well as the rapid development in recent years of X-ray FELs in China.
