摘要：
我们提出了一种基于短脉冲激光驱动等离子体X射线源的时间分辨X射线衍射装置。所采用的模块化设计提供了高度灵活性，可根据特定应用的具体要求（如X射线光学、样品环境）调整装置。本文讨论的配置已针对高角度/动量分辨率进行了优化，使用来自Ti线靶的K$_α$辐射（4.51 keV），并结合环形弯曲晶体对发射辐射进行收集、单色化和聚焦。每个脉冲以10 Hz重复频率向样品输送$2\times 10^5$个Ti-K$_{\alpha1}$光子，相对带宽为$10^{-4}$。这使得能够对材料摇摆曲线的瞬态变化进行高动态范围（$10^4$）测量，例如由激光触发应变波引起的变化。
英文摘要：
We present a set-up for time-resolved X-ray diffraction based on a short pulse, laser-driven plasma X-ray source. The employed modular design provides high flexibility to adapt the set-up to the specific requirements (e.g. X-ray optics, sample environment) of particular applications. The configuration discussed here has been optimized towards high angular/momentum resolution and uses K$_α$-radiation (4.51 keV) from a Ti wire-target in combination with a toroidally bent crystal for collection, monochromatization and focusing of the emitted radiation. $2\times 10^5$ Ti-K$_{\alpha1}$ photons per pulse with $10^{-4}$ relative bandwidth are delivered to the sample at 10 Hz repetition rate. This allows for high dynamic range ($10^4$) measurements of transient changes of the rocking curves of materials as for example induced by laser-triggered strain waves.
