A new timing system based on White Rabbit (WR) is being developed for the upcoming FAIR facility at GSI, in collaboration with CERN, other institutes and industry partners. The timing system is responsible for the synchronization of nodes with nanosecond accuracy and distribution of timing messages, which allows for real-time control of the accelerator equipment. WR is a fully deterministic Ethernet-based network for general data transfer and synchronization, which is based on Synchronous Ethernet and PTP. The ongoing development at GSI aims for a miniature timing system, which is part of a control system of a proton source, that will be used at one of the accelerators at FAIR. Such a timing system consists of a Data Master generating timing messages, which are forwarded by a WR switch to a handful of timing receiver. The next step is an enhancement of the robustness, reliability and scalability of the system. These features will be integrated in the forthcoming CRYRING control system in GSI. CRYRING serves as a prototype and testing ground for the final control system for FAIR. The contribution presents the overall design and status of the timing system development.

The White Rabbit (WR) project started off to provide a sequencing and synchronization solution for the needs of CERN and GSI. Since then, many other users have adopted it to solve problems in the domain of distributed hard real-time systems. The paper discusses the current performance of WR hardware, along with present and foreseen applications. It also describes current efforts to standardize WR under IEEE 1588 and recent developments on reliability of timely data distribution. Then it analyzes the role of companies and the commercial Open Hardware paradigm, finishing with an outline of future plans.
