Giant Radio Array for Neutrino Detection

GRAND is a next-generation detector designed to collect ultra-high energy cosmic particles as cosmic rays, neutrinos and photons, in order to solve the long-standing mystery of their origin. It will consist in an array of 200,000 radio antennas deployed over 200,000 square kilometers, about the size of Great Britain, in favorable mountainous locations in the world. It will be the largest ground detector ever built. [Text and image from https://grand.cnrs.fr/]
