This project will develop advanced broadband radio receivers and antennas to be buried in the ice below South Pole Station for detecting the interaction of ultra-high energy (PeV) astrophysical neutrinos with nuclei in the ice. Ultra-high energy, with energies exceeding 1015 eV, could be used to discover the sources of the very highest energy cosmic rays, the source of which is a long standing open question. The radio detection technique is complementary to the more common detection of light produced by high energy particles because the optical techniques begin to lose sensitivity at the ultra-high energies near the threshold for the radio technique. From there on up in energy, the sensitivity of the radio detectors is expected to increase dramatically. This rising sensitivity with energy works well with the steeply declining flux of cosmic rays. The University of Kansas the leading institution in the development of these detectors in the United States.

该项目将开发先进的宽带无线电接收器和天线，埋在南极站下面的冰中，用于探测超高能天体物理中微子与冰中原子核的相互作用。 能量超过1015 eV的超高能量可以用来发现能量最高的宇宙射线的来源，而宇宙射线的来源是一个长期悬而未决的问题。 无线电探测技术是对由高能粒子产生的光的更常见的探测的补充，因为光学技术开始在无线电技术的阈值附近的超高能量处失去灵敏度。 从那里开始，在能量上，无线电探测器的灵敏度预计将显着增加。 随着能量的增加，这种灵敏度的上升与急剧下降的宇宙射线通量很好地结合在一起。 堪萨斯大学是美国开发这些探测器的领先机构。
