GRAND: status and perspectives
Year: 2024
Type: conference-paper
Abstract: GRAND (the Giant Radio Array for Neutrino Detection) is a proposed next-generation observatory of ultra-high-energy neutrinos, cosmic rays, and gamma rays of cosmic origin, with energies exceeding about 100 PeV. GRAND is envisioned as a collection of large-scale ground arrays of self-triggered radio antennas that target the radio emission from extensive air showers initiated by UHE particles. Three prototype arrays are in operation: GRAND@Nançay in France, GRAND@Auger in Argentina, and GRANDProto300 in China. They test the detection principle and technology of GRAND, in preparation for its next phase, consisting of two arrays of 10'000 antennas each, in the Northern and Southern hemispheres, to be deployed from 2030 on. We present the concept of GRAND, its science goals, the status of the prototypes, their first measurements, and the technical and scientific perspectives that these measurements open for the field.
