Since there discovery in 1895, X-rays lead to new insight in structure of matter previously inaccessible with conventional optical methods. Based on the ability to provide high spatial resolution, researchers from a broad diversity of scientific horizons are anticipating X-ray pulses to probe dynamical processes with high temporal resolution. This quest motivates the construction of X-ray Free Electron Laser facilities around the world providing femtosecond high brilliance X-ray pulses. There drawback besides a huge initial financial investment (billions of dollars) is limited availability, restraining the number of performed experiments.

自1895年发现以来，X射线使人们对物质结构有了新的认识，这是以前用传统光学方法无法达到的。基于提供高空间分辨率的能力，来自各种科学领域的研究人员正在期待X射线脉冲以高时间分辨率探测动力学过程。这一探索激发了世界各地的X射线自由电子激光设施的建设，提供飞秒高亮度X射线脉冲。除了巨大的初始财务投资（数十亿美元）之外，缺点是可用性有限，限制了执行实验的数量。
