摘　　要：为满足负离子源中性束注入系统对定时同步的功能需求,设计了射频负离子源分布式定时同步系统。通过精密时钟同步协议对中性束系统中的各子系统进行同步控制,建立统一的时钟基准。实现精准控制各子系统的投入时序以及运行时间,有效提高定时精准度,保证每炮实验完整有序进行。实验测试结果表明:目前同步控制精度控制在1μs以下,满足时序控制需求。In order to meet the functional requirements of the neutral beam injection system of the negative ion source,the distributed timing synchronization system of RF-Driven negative ion source is designed.The precision time protocol will simultaneously control the subsystems of the neutral beam system and establish a unified clock reference,so as to achieve accurate control of the input timing and running time of each subsystem,effectively improve timing accuracy,and ensure the complete and orderly conduct of each experiment.The experimental results show that the timing control accuracy is less than 1μs,which meets the requirements of the timing control.
