A Wikievening: IceCube Neutrino Detector.
...is currently under construction under Amundsen-Scott South Pole Station.
The main goal of the experiment is to detect neutrinos in the high energy range, which spans from 1011 to about 1021 eV. The neutrinos are not detected themselves. Instead, the rare instance of a collision between a neutrino and an atom within the ice is used to deduce the kinematical parameters of the incoming neutrino. Current estimates predict the detection of about one thousand such events per day in the fully constructed IceCube detector. Due to the high density of the ice, almost all detected products of the initial collision will be muons.
