Neutrino Oscillation Measurements with IceCube

The IceCube Neutrino Telescope [1] is a multipurpose discovery experiment under construction at the South Pole. It is currently about half completed and is taking physics data. Upon completion in 2011, IceCube will instrument a volume of one cubic kilometer with 4800 Digital Optical Modules (DOMs). These will be vertically spaced with 17 m separation at a depth between 1450 m and 2450 m in the ice on 80 strings that are arranged in a hexagonal pattern with an inter-string spacing of about 125 m. An additional six strings will be deployed in-between the hexagonal pattern at the center of IceCube in the deep very clean ice region with DOMs more densely spaced and equipped with high quantum efficiency photomultiplier tubes. They will form together with the adjacent IceCube strings the Deep Core [2] subdetector. The first of these Deep Core strings will be deployed at the end of this year.
