Description
IceCube Neutrino Observatory, illustration. 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, spheres, lower left) deployed at depths between 1400 and 2400 metres (Empire State Building shown for scale). The modules detect the light (Cherenkov radiation) produced when neutrinos interact with ice. Detection events are shown in yellow-orange. The inset at lower right shows the internal module structure, which includes an RTV (room-temperature-vulcanization) gel, a photomultiplier tube (PMT), a light-emitting diode (LED) flasher, a glass pressure capsule, and a mu-metal grid (a nickel-iron soft magnetic alloy to shield the detector).
