Abstract

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.
