Improving the Analysis Efficiency of Ground-Based Radio Neutrino Detectors at the South Pole
The Askaryan Radio Array (ARA) is a South Pole-based experiment looking to detect radio emission induced by an ultra-high-energy cosmic neutrino interacting in the ice. The newest ARA station is equipped with a novel phased-array trigger designed to lower the trigger threshold by adding signal chann...
