The Antarctic Ross Ice-Shelf ANtenna Neutrino Array (ARIANNA) concept uses the Ross Ice Shelf near the coast of Antarctica to increase the sensitivity to ultra-high-energy cosmogenic neutrinos by roughly an order of magnitude when compared to the sensitivity of existing detectors and those under construction. Therefore, ARIANNA can test a wide variety of scenarios for neutrino production and probe for physics beyond the standard model by measuring the neutrino cross-section at the center of mass energies near 100 Tera-electron-Volts. This is made possible by the capability of ARIANNA to capitalize on several remarkable properties of the Ross Ice Shelf. For example, shelf ice is now measured to be relatively transparent to electromagnetic radiation at the radio frequencies of interest, and the water-ice boundary below the shelf behaves like a mirror that reflects radio signals from downgoing neutrinos back up to the surface antennas. The ability to operate continuously for nearly six months (or possibly more with the addition of wind power), the low energy threshold (~3x1017 electron-Volts), and a field of view of more than half the sky, combine to make ARIANNA a highly sensitive neutrino detector.
Field Season Overview
Antarctic Ross Ice-Shelf Antenna Neutrino Array (ARIANNA) is a neutrino telescope consisting of Ultra-High Energy detector stations arranged in a grid on the Ross Ice Shelf. This season, four team members will travel by helicopter to the ARIANNA camp site at Moore's Bay on the Ross Ice Shelf. They will stay for two weeks to perform maintenance on the ARIANNA array. An ASC field coordinator will provide put-in and pull-out assistance for a maximum of four days.
