Title: Cosmic-ray Physics with IceCube
The recently completed IceCube detector at the South Pole has two components--the neutrino telescope with 5160 sensors between 1.45 and 2.45 kilometers deep in the ice and an air shower array on the surface called IceTop. Surface detectors and deep detectors all operate within a unified data acquisition system to form a single three-dimensional array that is one square kilometer in area by 2.5 kilometers deep. Because of its size, IceCube has unprecedented sensitivity for high-energy neutrinos, whether produced by cosmic-ray interactions in the atmosphere or as byproducts of cosmic-ray acceleration in distant astrophysical sources. The theme of this presentation will be the connections between neutrinos and cosmic-rays over an energy range from TeV to 100 EeV, with illustrations based on the latest results from IceCube.
