H. Landsman (for the IceCube Collaboration), L. Ruckman, G.S., Varner

TL;DR
AURA is a radio frequency extension to IceCube aiming to detect ultra-high-energy neutrinos using radio wave technology, leveraging ice's transparency and Cherenkov emission to expand detection volume and physics reach.
Contribution
The paper introduces the deployment and calibration of radio frequency detector clusters within IceCube, advancing large-scale radio detection technology for neutrino astronomy.
Findings
Successful deployment and calibration of RF clusters at 1300m and 300m depths
Demonstrated detector performance suitable for large-scale neutrino detection
Potential to extend IceCube's sensitivity into EeV-ZeV energy regime
Abstract
The excellent radio frequency transparency of cold polar ice, combined with the coherent Cherenkov emission produced by neutrino-induced showers when viewed at wavelengths longer than a few centimeters, has spurred considerable interest in a large-scale radio-wave neutrino detector array. The AURA (Askaryan Under-ice Radio Array) experimental effort, within the IceCube collaboration, seeks to take advantage of the opportunity presented by IceCube drilling through 2010 to establish the radio frequency technology needed to achieve 100-1000 km^3 effective volumes. In the 2006-2007 Austral summer 3 deep in-ice radio frequency (RF) clusters were deployed at depths of 1300m and 300m on top of the IceCube strings. Additional 3 clusters will be deployed in the Austral summer of 2008-2009. Verification and calibration results from the current deployed clusters are presented, and the detector…
