基于同步辐射的穆斯堡尔谱学已经成为一种能够研究各种穆斯堡尔同位素的有用技术。对于一个典型的实验设置，与雪崩光电二极管（APD）检测器中的脉冲高度（即能量）相关的信息尚未得到有效利用。利用APD信号的时间和能量同时测量系统，研制了时间和能量分辨穆斯堡尔谱系统。在该系统中，脉冲高度信息通过应用于来自APD的分频信号之一的幅度-时间转换器转换为时间信息。相应的时间信息与另一个分割信号分开处理。两个信号都由多通道定标器在逐事件数据采集过程中记录。来自穆斯堡尔传感器的速度信息也被记录为每个信号事件的标签。因此，在数据收集过程之后，可以重建具有任何时间和能量窗口的穆斯堡尔谱。该系统可用于时间和能量分辨穆斯堡尔光谱学的许多目的，并显示出与其他快速探测器和各种类型的实验使用显着的承诺。
Synchrotron-radiation based Mössbauer spectroscopy has become a useful technique capable for investigating various Mössbauer isotopes. For a typical experimental setup, the information associated with the pulse height (that is, energy) in an avalanche photodiode (APD) detector has not been used effectively. By using a system for simultaneous measurement system of time and energy associated with the APD signal, a system for the time-and energy-resolved Mössbauer spectroscopy has been developed. In this system, the pulse height information was converted to the time information through an amplitude-to-time converter applied to one of the divided signals from the APD. The corresponding time information was processed separately from another one of the divided signals. Both signals are recorded by a multi-channel scaler in an event-by-event data acquisition process. The velocity information from the Mössbauer transducer was also recorded as a tag for each signal event. Thus, the Mössbauer spectra with any time-and energy-window can be reconstructed after the data collection process. This system can be used for many purposes in time-and energy-resolved Mössbauer spectroscopy, and shows significant promise for use with other fast detectors and for various types of experiments.
