We present an experimental setup of a laser-driven x-ray plasma source for femtosecond x-ray diffraction. Different normalization schemes accounting for x-ray source intensity fluctuations are discussed in detail. We apply these schemes to measure the temporal evolution of Bragg peak intensities of perovskite superlattices after ultrafast laser excitation.
我们展示了一种用于飞秒X射线衍射的激光驱动X射线等离子体源的实验装置。详细讨论了考虑X射线源强度波动的不同归一化方案。我们应用这些方案来测量超快激光激发后钙钛矿超晶格布拉格峰强度的时间演化。
