Accelerator node clock synchronization system based on White Rabbit time synchronization protocol

Abstract： 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.
