Design and Performance of the ARIANNA HRA-3 Neutrino Detector Systems
We report on the development, installation, and operation of the first three of seven stations deployed at the ARIANNA site's pilot Hexagonal Radio Array (HRA) in Antarctica. The primary goal of the ARIANNA project is to observe ultrahigh energy (> 100PeV) cosmogenic neutrino signatures usin...
