The Askaryan Radio Array (ARA) is a new detector designed to detect a few GZK neutrinos a year. It measures the enhanced radio-frequency radiation emitted during the interaction of the neutrino in Antarctic ice sheet. The detection is based on the Askaryan effect, an idea by Gurgen Askaryan [1][2]

This detection technique is also being used by the Antarctic Impulse Transient Antenna (ANITA) and the Radio Ice Cerenkov Experiment (RICE) detectors. The ARA experiment will be built around the IceCube experiment, and will cover an area of approximately 100 square kilometers.
