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:
Two field team members will deploy, with field assistance from tow Field Support and Training personnel, to the Moore's Bay site. They will raise previously-cached equipment and stations, and swap electronics to reestablish the remote link.
