Optical sensor Martin A. Pomerantz Observatory (MAPO)
AMANDA Detector @ South Pole Antarctica • 677 OMs • on 19 strings • since Jan 2000
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 nm + N m+ X
SPASE/AMANDA Coincidence Experiment • Electronic component of • air showers detected by • SPASE • Primary CR direction • and energy • Penetrating muons detected by • AMANDA • Very good tool for • Cosmic Ray mass composition • & • AMANDA calibration SPASE Skiway
IceTop AMANDA • 1 station on top of each IceCube string • 2 ice tanks per station • 2 DOMs in each tank • IceTop will detect Air Showers • of energies 1014 eV to 1018 eV South Pole Skiway • 4800 PMT • Instrumented volume: 1 km3 (1Gt) • 80 Strings • IceCube is designed to detect neutrinos of all flavors at energies from 107 eV to 1020 eV 1400 m IceCube 2400 m
