Detection of neutrino-induced air showers by the artificial neural network FPGA trigger

The origin of ultra-high-energy cosmic rays (UHECRs) is still a mystery. Neutrinos are a fundamental element in an astrophysics puzzle. Extensive air showers generated by UHECRs contain neutrinos interacting with other particles via charged and neutral currents. Due to a very low cross-section of neutrinos and in consequence due to a very low rate of neutrino-induced events their detection is a significant challenge requiring sophisticated algorithms and high-resolution hardware.
