This ground-based, interferometric, phased-array, high-energy neutrino detector is designed to discover the highest energy particles in our universe. Radio emission from particle cascades induced by neutrinos in glacial ice will be observed using an interferometric phased array that will be co-located with the Askaryan Radio Array (ARA) (A-107-S). These observations will be used to verify and extend IceCube astrophysical neutrino flux data to higher energies, inform design decisions for future detectors, and search for high-energy neutrinos. This project will be located at the South Pole to take advantage of the radio clarity and depth of the ice.

Field Season Overview

The previously-retrofitted phased array trigger system is currently operational, as is the rest of ARA. This season, a team of three will travel by snowmobile and PistenBully from South Pole Station to the ARA 5 site, where they’ll perform calibration and change antenna orientations in an installed surface antenna array.
