Neutrino particle detector. Computer artwork of the Antarctic muon and neutrino detector array (AMANDA,bottom),a neutrino telescope situated beneath the Amundsen-Scott South Pole Station (near centre of continent on map),used to identify and characterise extra-solar neutrino sources. Each vertical string holds numerous optical modules (red),which contain a photomultipler tube. The modules detect radiation given off when neutrinos passing through the Earth from the Northern hemisphere collide with the nuclei of oxygen and hydrogen atoms in the water ice,producing a muon and a hadronic shower. By analysing the timing of photon hits the optical modules can determine the direction of the original neutrino | |
