NW14A是在光子工厂先进环上为100ps时间分辨x射线实验新建造的波束线。该光束线设计用于进行各种时间分辨x射线测量，如时间分辨衍射、散射和x射线吸收精细结构。它的多功能性被各种仪器所允许，包括两个波动器，三个衍射仪，两个脉冲激光系统和一个x射线斩波器。在NW14A的100 ps时间尺度上检测结构变化的潜力通过两个例子证明了有机晶体的光诱导结构变化和溶液中的光解离。
NW14A is a newly constructed undulator beamline for 100 ps time-resolved X-ray experiments at the Photon Factory Advanced Ring. This beamline was designed to conduct a wide variety of time- esolved X-ray measurements, such as time-resolved diffraction, scattering and X-ray absorption fine structure. Its versatility is allowed by various instruments, including two undulators, three diffractometers, two pulse laser systems and an X-ray chopper. The potential for the detection of structural changes on the 100 ps time scale at NW14A is demonstrated by two examples of photo-induced structural changes in an organic crystal and photodissociation in solution.
