The GRANDProto300 experiment: a pathfinder with rich astroparticle and radio-astronomy science case
2019 July 22
The GRANDProto300 (GP300) experiment is the first stage of the Giant Radio Array for Neutrino Detection (GRAND) project. It will be deployed between 2020 and 2021 in a radio-quiet area, at 3000 m of altitude at the rim of the Tibetan plateau, over a total surface of 200 km2. The primary goal of GP300 is to demonstrate the viability of the GRAND detection concepts. It will provide a unique test bench to develop and validate new identification and reconstruction techniques for the radio detection of very inclined air-showers, in the perspective of the next stages of GRAND. GP300 also proposes a rich science case, which includes accurate measurements of cosmic-ray and gamma-ray air-showers in the energy range of 30 PeV to 1 EeV, and a wide-field survey of the Epoch of Reionization, and of radio transients such as Giant Radio Pulses and Fast Radio Bursts.
