IceCube. How it Works.
E N D
IceCube How it Works IceCube Neutrino Observatory is a neutrino detector located in Antarctica. University of Wisconsin-Madison is mainly in charge of the observatory, but the detector is a multi-national effort. The detector consists of over 5000 digital optical modules (DOMs) embedded roughly 2 kilometers under the arctic ice. (The images on the top right are of the IceCube detector top and a DOM. Underneath is a picture of one of the holes with the DOMs.) When a neutrino interacts with the arctic ice, Cherenkov radiation is produced. This is detected by the DOMs. The DOMs are located deep under the ice because the ice is very clear down there, making it optimal to detect the radiation. It is also very dark, allowing the DOMs to collect accurate data. The DOMs take measurements on the light detected, which allows analysis on where the neutrinos came from and how much energy they had. Deep Space Neutrinos Detected and IceCube Neutrino Observatory Deep Space Neutrinos Detected IceCube detected 28 neutrinos which are believed to have originated from outside the solar system. These neutrinos had energies of above 30 TeV. These neutrinos are not produced in the atmosphere. The energies of the detected neutrinos are much greater than the atmospheric neutrinos. The origin of these neutrinos could be black holes, galactic nuclei, supernova, and other cosmic events. The detection of deep space neutrinos opens up a whole new door for the field of astronomy. Analysis of the neutrinos can show where and what they came from. Deep space neutrinos can allow a new way to view the cosmos.
