  Two synchronization layers for timing systems in large experimental physics control systems are compared. White Rabbit (WR), which is an emerging standard, is compared against the well-established event based approach. Several typical timing system services have been implemented on an FPGA using WR to explore its concepts and architecture, which is fundamentally different from an event based. Both timing system synchronization layers were evaluated based on typical requirements of current accelerator projects and with regard to other parameters such as scalability. The proposed design methodology demonstrates how WR can be deployed in future accelerator projects.

  Synchrotron accelerators with multiple ion sources and beam lines require a high degree of flexibility to define beam cycle timing sequences. We have therefore decided to design a ready-to-use accelerator timing system based on off-the-shelf hardware and software that can fit mid-size accelerators and that is easy to adapt to specific user needs. This Real Time Event Distribution Network (REDNet) has been developed under the guidance of CERN within the MedAustron-CERN collaboration. The system based on the MRF transport layer has been implemented by Cosylab. While we have used hardware on NI PXIe platform, it is straightforward to obtain it for other platforms such as VME. The following characteristics are key to its readiness for use: (1) turn-key system comprising hardware, transport layer, application software and open integration interfaces, (2) performance suitable for a wide range of accelerators, (3) multiple virtual timing systems in one physical box, (4) documentation developed according to V-model. Given the maturity of the development, we have decided to make REDNet available as a product through our industrial partner.
