An experimental system, SPINETT (SACLA Pump-probe INstrumEnt for Tracking Transient dynamics), dedicated for ultrafast pump-probe experiments using X-ray free-electron lasers has been developed. SPINETT consists of a chamber operated under 1 atm helium pressure, two Von Hamos spectrometers, and a large two-dimensional detector having a short work distance. This platform covers complementary X-ray techniques; one can perform time-resolved X-ray absorption spectroscopy, time-resolved X-ray emission spectroscopy, and time-resolved X-ray diffuse scattering. Two types of liquid injectors have been prepared for low-viscosity chemical solutions and for protein microcrystals embedded in a matrix. We performed a test experiment at SPring-8 Angstrom Compact free-electron LAser and demonstrated the capability of SPINETT to obtain the local electronic structure and geometrical information simultaneously.

多功能实验系统，用于利用X射线自由电子激光器跟踪超快化学反应。

开发了一种实验系统SPINETT（用于跟踪瞬态动力学的SACLA泵浦探针InstrumEnt），专门用于使用X射线自由电子激光进行超快泵浦探针实验。SPINETT包括一个在1个大气压氦气压力下运行的腔室，两个Von Hamos光谱仪和一个工作距离较短的大型二维探测器。该平台涵盖了互补的X射线技术；可以执行时间分辨X射线吸收光谱，时间分辨X射线发射光谱和时间分辨X射线漫散射。已经准备了两种类型的液体注射器，用于低粘度化学溶液和嵌入基质中的蛋白质微晶。
