We built a two-mirror based X-ray split and delay (XRSD) device for soft X-rays at the Linac Coherent Light Source free electron laser facility. The instrument is based on an edge-polished mirror design covering an energy range of 250 eV-1800 eV and producing a delay between the two split pulses variable up to 400 femtoseconds with a sub-100 attosecond resolution. We present experimental and simulation results regarding molecular dissociation dynamics in CHI and CO probed by the XRSD device. We observed ion kinetic energy and branching ratio dependence on the delay times which were reliably produced by the XRSD instrument.
我们在直线加速器相干光源自由电子激光设施上构建了一种基于双镜的软X射线分光延迟（XRSD）装置。该仪器基于边缘抛光镜设计，能量范围为250电子伏特至1800电子伏特，可产生两个分光脉冲之间高达400飞秒的可变延迟，分辨率低于100阿秒。我们展示了关于XRSD装置探测的CHI和CO中分子解离动力学的实验和模拟结果。我们观察到离子动能和分支比与XRSD仪器可靠产生的延迟时间有关。
