@

South Pole

Antarctica

  • 677 OMs

  • on 19 strings

  • since Jan 2000


High energy cosmic ray physics neutrino astronomy

  • AMANDA Neutrino Detection Principle

  • Neutrino interacts in ice

  • surrounding the detector

  • Muontrack is reconstructed by

  • mapping the Cherenkov photon

  • times recorded by the Optical Modules
