我们描述了一个磁瓶飞行时间电子光谱仪设计的时间分辨光电子能谱的液体微射流使用极端紫外和X射线辐射。光谱仪可以很容易地重新配置，这取决于实验要求和感兴趣的能量范围。为了提高在高电子动能下的能量分辨率，可以通过电极堆或减速网格施加减速电势，并且可以连接飞行管延伸部以增加飞行时间。设计了一种门控电子检测器，用于抑制圆柱形液体微射流表面散射光产生的强寄生信号。该探测器具有两级倍增功能，微通道板加上快速响应闪烁体，然后是图像增强光子探测器。光谱仪的性能进行了测试，在SPring-8和SACLA，和时间分辨的光电子能谱进行测量的超快电荷转移到溶剂反应的NaI水溶液中的200 nm的紫外泵浦脉冲从台式超快激光器和5.5 keV的硬X射线探测脉冲从SACLA。
We describe a magnetic bottle time-of-flight electron spectrometer designed for time-resolved photoemission spectroscopy of a liquid microjet using extreme UV and X-ray radiation. The spectrometer can be easily reconfigured depending on experimental requirements and the energy range of interest. To improve the energy resolution at high electron kinetic energy, a retarding potential can be applied either via a stack of electrodes or retarding mesh grids, and a flight-tube extension can be attached to increase the flight time. A gated electron detector was developed to reject intense parasitic signal from light scattered off the surface of the cylindrically shaped liquid microjet. This detector features a two-stage multiplication with a microchannel plate plus a fast-response scintillator followed by an image-intensified photon detector. The performance of the spectrometer was tested at SPring-8 and SACLA, and time-resolved photoelectron spectra were measured for an ultrafast charge transfer to solvent reaction in an aqueous NaI solution with a 200 nm UV pump pulses from a table-top ultrafast laser and the 5.5 keV hard X-ray probe pulses from SACLA.
