IceCube neutrino detection event, illustration. The interaction of a neutrino with an ice molecule (red) has produced a secondary particle, a muon (right), that is moving at relativistic speed, leaving a trace of blue Cherenkov radiation. IceCube (completed 2010) is an international high-energy neutrino observatory in the ice below the Amundsen-Scott South Pole Station. The detection area consists of some 80 strings of 60 digital optical modules (DOM) deployed at depths between 1400 and 2400 metres. Neutrinos are elementary particles that are very difficult to detect and study. The modules detect the Cherenkov radiation produced when neutrinos interact with ice. | |
