White Rabbit Collaboration

Facts for Prelims (FFP)

 

Source: CERN

 Context: CERN has introduced the White Rabbit Collaboration to promote the adoption of its White Rabbit (WR) technology, initially developed to synchronize devices in particle accelerators with sub-nanosecond precision.

  • This technology has applications beyond particle physics and has been incorporated into the Precision Time Protocol (PTP) standard.
  • Unlike other technologies, WR is open-source and based on standards, allowing companies and institutes to adapt it to their needs.

 

White Rabbit (WR) is a technology developed at CERN, the European Organization for Nuclear Research, to provide time synchronization and data transfer for the LHC accelerator chain.

WR is a deterministic Ethernet-based network that provides sub-nanosecond accuracy and picosecond precision of synchronization. 

 It uses the Precision Time Protocol to achieve sub-nanosecond accuracy, which allows for precise adjustment of clock phase and offset. 

WR also provides the flexibility and modularity of real-time Ethernet networks.
