建立了一个用于时间分辨实验的时间分辨和能量色散型光电子探测器，用于激光和同步辐射联合泵浦多探测实验。约1纳秒的时间分辨率的检测器允许的光电子信号的分配到一个特定的同步辐射脉冲的任何填充模式的第三代同步加速器储存环。这导致由同步辐射脉冲宽度给出的总体时间分辨率，其在柏林的同步辐射设施BESSY处为30 ps。应用泵浦多探针技术演示了结合激光和同步辐射的时间分辨光电发射实验。
A time-resolving and energy-dispersive photoelectron detector for time-resolved experiments has been set up for pump–multiple-probe experiments with combined laser and synchrotron radiation. The time resolution of the detector of about 1 ns allows an assignment of the photoelectron signal to a specific synchrotron radiation pulse for any filling pattern of third-generation synchrotron storage rings. This leads to an overall temporal resolution given by the synchrotron radiation pulse width, which is 30 ps at the synchrotron radiation facility BESSY, Berlin. Application of the pump–multiple-probe technique is demonstrated for time-resolved photoemission experiments with combined laser and synchrotron radiation.
