GRAND
GRAND (Giant Radio Array for Neutrino Detection) is a detector whose main goal is to detect ultra-high-energy particles. It will cover an area of approximately 200,000 km2 with 200k radio antennas deployed in mountainous locations in the whole world. GRAND may be able to detect cosmic neutrino and cosmic-ray sources, elucidating the long-standing problem of the origin of the most energetic particles in the universe.
