GRANDProto300, a pathfinder for autonomous radio detection of UHECRs — •Anne Zilles — Institut d’Astrophysique de Paris, Paris, France
GRANDProto300, acting as a pathfinder for the future Giant Radio Array for Neutrino Detection (GRAND), is planned as an array of 300 antennas deployed over ∼ 300 km2. Its main goal is to demonstrate the viability of detection principle of GRAND: from radio data alone, to trigger on nearly horizontal air showers, separate the signal from the background, and reconstruct the properties of the primary particles with a precision similar to standard techniques used for cosmic-ray detection. With 105 detected CR events above 107.5 GeV already in the first year, GRANDProto300 is placed in a privileged position to study the transition between Galactic and extragalactic cosmic rays. With the extension by a ground array of particle detectors, hybrid detection will allow an independent measurement of the electromagnetic and muonic component of the shower. In this contribution we will present the science goals, preliminary design, performance goals and current status of the GRANDProto300 project.
