Description
The Giant Radio Array for Neutrino Detection (GRAND) is a future observatory with unprecedented sensitivity to ultra-high energy (UHE) neutrinos. UHE neutrinos and cosmic rays (CR) induce extensive air showers (EAS) when they enter Earth's atmosphere. These EAS emit radio signals, which offer information on the mass, energy and arrival direction of the incoming CR.
GRAND is planned as a network of radio detection antennas, covering a total area of
Radio measurements are highly affected by anthropic signals, which can be several orders of magnitude more frequent than EAS. In order to reliably distinguish EAS events from noise, the NUTRIG project is developing an efficient and autonomous radio trigger, which will be verified with GP300. The first-level trigger describes the selection of an antenna signal, while the second-level trigger refines this selection according to information of all antennas triggered during the same event. This talk will cover the concept of the GRAND experiment and give an overview of the development of a second-level trigger for the autonomous detection of air shower radio emission.
