Description
The Giant Radio Array for Neutrino Detection (GRAND) is a planned ground-based detector of ultra-high-energy cosmic rays (UHECRs), gamma rays and neutrinos. It is designed to consist of 20 independent sub-arrays of 10,000 radio antennas each, deployed over an area of 10,000 km$^2$ in radio-quiet locations. One of the primary goals of GRAND is to find the origin of UHECRs via detecting high-energy neutrinos. This is possible due to GRAND's large exposure, sub-degree angular resolution, and high sensitivity to UHE neutrinos. Within 3 years of operation, GRAND is expected to reach an unprecedented sensitivity, making it possible to detect cosmogenic and astrophysical neutrinos. The first stage of antenna deployment for the GRAND prototype has already started in Dunhuang, China and is currently taking calibration data with 14 antennas. In this talk, I will give a brief introduction to the GRAND detector, its science goals, and current status.
