Description
Time synchronization to sub-nsec precision of detector systems
distributed over large areas
is requested in modern astroparticle experiments,
like upcoming Gamma-Ray and Cosmic-Ray detector arrays,
to ensure optimal pattern recognition and background rejection.
White-Rabbit (WR), a new ethernet-based technology for time and frequency transfer,
is well suited for this purpose.
It allows clock-synchronziation and trigger-time stamping to sub-nanosecond precision
over multi-km scale distances.
This technology also supports new complex and flexible topological trigger strategies,
based on ethernet-routed timestamps.
We present design and results from the White-Rabbit installation
in the TAIGA-HiSCORE array, gained over several years;
and discuss upcoming applications like e.g. the Cherenkov-Telescope-Array (CTA) and
high energy neutrino telescopes.
Excellent field performance, design flexibility at timing and triggering level,
open soft- and hardware approach with strong community support and documentation,
commercial availability,
easy integration into modern system monitoring architectures,
and the striking cost-efficiency make White-Rabbit
a new de-facto experimental standard,
and advantageous over custom-made solutions.
