摘　　要：提出了一种基于白兔时间同步协议,利用SPARTAN-6系列现场可编程门阵列(Field-Programmable Gate Array,FPGA)实现多节点亚纳秒级别时间同步,并通过测量触发信号到达时间,根据设置的延迟进行恢复,从而实现高于120 ps时间分辨率。该方法能够精确控制多节点信号发生的绝对时间,具有广泛的应用前景。特别地,该方法可应用于同步辐射加速器中,提高实验数据的准确性和稳定性,有望在材料科学、生物学和化学等领域中得到广泛应用。该研究成果为同步辐射加速器的研究和实验提供了新的解决方案,有望推动同步辐射技术的发展,为科学研究和工程应用提供更多可能。This paper proposes a multi-node sub-nanosecond level time synchronization method based on the White Rabbit time synchronization protocol,and it is implemented using SPARTAN-6 series FPGAs.By measuring the trigger signal arrival time and recovering them based on the set delay,a time resolution higher than 120 ps is achieved.This method can precisely control the absolute occurrence time of signals from multiple nodes and has broad application prospects,especially in synchrotron accelerator experiments.It can improve the accuracy and stability of experimental data and may find widespread applications in material science,biology,chemistry,and other fields.The research results presented in this paper provide a new solution for synchrotron accelerator research and experiments,and have the potential to advance the development of synchrotron radiation technology,thereby providing more possibilities for scientific research and engineering applications.
