摘要
使用AVR单片机设计实现了合肥光源光阴极微波电子枪的时序同步电路,满足了该系统的特殊触发要求,帮助电子枪系统顺利实现出束;以极低廉成本实现了同类系统采用昂贵专用设备提供的功能;同时在实验结果基础上根据设计方案分析了信号抖动的来源,合理解释了抖动大小,并给出了提高精度升级系统的方案。
The timing synchronization circuit of Hefei Free Electron Laser （FEL） was devetopecl by means of an AVR MCU, which meets the specific triggering requirement and enables the electron beam to be generated successfully. This can realized the same function for similar systems with expensive special equipment at a very low cost. Moreover, based on the experiment results and according to our scheme, the cause of signal jitter was analyzed, the quantity of signal iitter was explained reasonably, and a scheme was given which can achieve higher precision and improve system performance.
