论文摘要
对于高强度质子加速器（例如J-PARC），必须进行精确稳定的时序系统。自2006年以来，在J-PARC的施工期间开发的原始计时系统一直没有重大问题。经过十年的操作，已经停用了信号传输的关键组成部分的光学模块。因此，已经开发和构建了J-PARC的下一代定时系统。新系统旨在就操作原则而言与原始系统兼容。新系统利用现代高速串行通信来传输时钟，参考触发器和类型代码。我们描述了下一代正时系统和当前状态的系统配置。
A precise and stable timing system is necessary for high intensity proton accelerators such as the J-PARC. The original timing system, which was developed during the construction period of the J-PARC, has been working without major issues since 2006. After a decade of operation, the optical modules, which are key components for signal transfer, were discontinued already. Thus, the next-generation timing system for the J-PARC has been developed and built. The new system is designed to be compatible with the original system in terms of the operating principle. The new system utilizes modern high speed serial communication for the transfer of the clock, reference trigger, and type code. We describe the system configuration of the next-generation timing system and current status.
