Description
Time-Synchronization to sub-nsec precision between detector subsystems
in large scale astroparticle physics experiments can efficiently be
provided by White-Rabbit (WR), a new ethernet-based
technology for time and frequency transfer.
We discuss principles and advantages of WR for distributed
detector arrays, which allows clock-synchronziation and
trigger-time stamping at sub-nanosecond precision;
as well as for complex and flexible topological trigger strategies,
based on ethernet-routed timestamps.
We describe a White-Rabbit implementation
at the Gamma-Ray facility HiSCORE (Siberia) for airshower
reconstruction;
and first experience with the next generation Zynq-based WR-ZEN
platform.
