ARA

    Overview

    The Askaryan Radio Array (ARA) is a radio detector array operating at the South Pole, designed for the detection of ultra-high-energy cosmic neutrinos using the emission of radio pulses produced by interactions in the Antarctic ice. This instrument is an R&D device geared toward an IceCube-Gen2 radio detector. The goal is to detect the cosmogenic neutrino flux at energies above 1017 eV.

    WIPAC contributions

    ARA collaborators at UW–Madison are primarily responsible for the integration, testing, drilling, and installation of the ARA instrumentation at the South Pole.  

    The scientific team is working on detector simulations, including neutrino interaction and photon propagation, data analysis, software development, event reconstruction tools, triggering studies, and detector operations.
