IceCube: A Cubic Kilometer Radiation Detector
  IceCube is a 1 km^3 neutrino detector now being built at the Amundsen-Scott South Pole Station. It consists of 4800 Digital Optical Modules (DOMs) which detect Cherenkov radiation from the charged particles produced in neutrino interactions. IceCube will observe astrophysical neutrinos with energies above about 100 GeV. IceCube will be able to separate \nu_\mu, \nu_e and \nu_\tau interactions because of their different topologies. IceCube construction is currently 50% complete.
