The X-ray Correlation Spectroscopy instrument is dedicated to the study of dynamics in condensed matter systems using the unique coherence properties of free-electron lasers. It covers a photon energy range of 4-25 keV. The intrinsic temporal characteristics of the Linac Coherent Light Source, in particular the 120 Hz repetition rate, allow for the investigation of slow dynamics (milliseconds) by means of X-ray photon correlation spectroscopy. Double-pulse schemes could probe dynamics on the picosecond timescale. A description of the instrument capabilities and recent achievements is presented.
X射线关联光谱仪致力于利用自由电子激光独特的相干特性研究凝聚态物质系统中的动力学。它覆盖4 - 25千电子伏特的光子能量范围。直线加速器相干光源的固有时间特性，特别是120赫兹的重复频率，使得通过X射线光子关联光谱法能够研究慢动力学（毫秒级）。双脉冲方案可探测皮秒时间尺度上的动力学。本文介绍了该仪器的功能及近期成果。
