摘　　要：针对同步辐射衍射探测的需求,设计了一套应用于三层GEM的自触发电子学系统。介绍了此电子学系统的整体架构、系统主要插件的电路设计、FPGA内部逻辑及算法的实现,以及与相应探测器配合的自触发读出方案。最后给出电子学系统初步调试结果。To meet the demand of synchrotron radiation diffraction probe, a time sequence＇s self-trigger read- out electronics system was designed for the triple - layer Gas Electron Multiplier detector. This article intro- duces the electronics system, including the overall framework the electronics system, the circuit design＇s details of main electronics modules, the method of FPGA internal logic and algorithms and the readout scheme of time sequence＇s self - trigger. Finally the preliminary results of the electronic modules were given.
