We report on the implementation of a high-count-rate charged particle imaging detector for two-color pump-probe experiments at the free electron laser in Hamburg (FLASH). In doing so, we have developed a procedure for finding the spatial and temporal overlap between the extreme UV free electron laser (FEL) pulses and the IR pulses, which allows for complete alignment of the setup in situations where the region of overlap between the FEL and the IR is not easily accessible by means of imaging optics.
我们报告了一种用于汉堡自由电子激光（FLASH）双色泵浦探测实验的高计数率带电粒子成像探测器的实现。在这个过程中，我们开发了一种方法来确定极紫外自由电子激光（FEL）脉冲与红外脉冲之间的空间和时间重叠，这使得在 FEL 和红外之间的重叠区域不容易通过成像光学来访问的情况下，能够完全对齐设置。
