为了做到定时信号,在时域上的样本点的同步辐射X射线脉冲之间的对齐,测量时间结构的储存环内实验笼样品点在时间分辨实验使用脉冲的同步辐射X射线的时间结构的储存环定义的一个基本步骤。在这项工作中,采用时间分辨X射线激发发光(trxeol)的设计和实现做测量。它是基于时间相关的单光子计数技术的原则。测量系统由一个光电倍增管探测器光谱仪,定时系统,一套核仪器模块和一个发光的氧化锌材料。测量是在X射线吸收精细结构谱线进行在上海同步辐射装置。结果表明,该方法可用于测量的存储环的时间结构的精度小于1纳秒。该测量系统还可用于光致发光材料的时间分辨研究。
In order to do alignment between the timing signal and the synchrotron X-ray pulse on the sample spot in the time domain, measuring time structure of the storage ring on the sample spot inside the experimental hutch is a foundational step during the time-resolved experiments using the pulsed synchrotron X-rays with the time structure defined by the storage ring. In this work, the method of time-resolved X-ray excited optical luminescence (TRXEOL) was designed and implemented to do the measurement. It is based on the principle of time-correlated single photon counting techniques. The measurement system consists of a spectrometer with a detector of photomultiplier tube, a timing system, a set of nuclear instrument modules and a luminescent material of zinc oxide. The measurement was performed on the X-ray absorbed fine structure spectrum beamline at Shanghai Synchrotron Radiation Facility. The results show that this method can be used to measure the time structure of the storage ring with a precision of less than 1 ns. The measurement system can also be used for the time-resolved research for the optical luminescent materials.
