Query: Development of next-generation timing system for the Japan Proton
  Accelerator Research Complex   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.
