Since there discovery in 1895, X-rays have led to new insight on the structure of matter, previously inaccessible with conventional optical methods. Over the last decade, researchers from a broad diversity of scientific horizons are awaiting X-ray pulses to probe dynamical processes with high temporal resolution. This quest motivates the construction of X-ray Free Electron Laser facilities. Their drawback besides a huge initial financial investment (billions of dollars) is limited availability, restraining the number of possible experiments.

自1895年发现以来，X射线已经导致了对物质结构的新见解，以前无法用传统的光学方法。在过去的十年里，来自不同科学领域的研究人员都在等待X射线脉冲以高时间分辨率探测动力学过程。这种探索激发了X射线自由电子激光设施的建设。除了巨大的初始投资（数十亿美元）之外，它们的缺点是可用性有限，限制了可能的实验数量。
