Askaryan Radio Array neutrino detector: status and design considerations for the future

The Askaryan Radio Array is a large-scale ultra-high energy neutrino detector under construction in the deep, radio-transparent ice of the South Pole. To date, 5 ARA stations have been deployed and 3 have been operated over the last several years. The new stations feature a larger baseline an interferometric trigger string. We report on the science, design, and sensitivity of the experiment along with design considerations for a full-scale array.
