At CERN, particles circle the LHC over 11000 times per second. This means components in the accelerator complex require minute timing accuracy and synchronisation down to 10 picoseconds. White Rabbit is a protocol developed at CERN for monitoring and controlling devices based on industrial networking technology, made available as open hardware and open source software.
In 2016, the technology attracted attention for its applicability in the field of smart electrical grids that have accurate synchonisation needs, where individuals and companies are no longer merely consumers of electricity but also co-creators. White Rabbit is currently being tested on the smart grid of the Milan financial district.
