IceCube : Toward a km^3 Neutrino Telescope

Since the end of the 2005-2006 austral summer, the IceCube detector consists of an array of 9 strings, deployed between 1450 m and 2450 m of depth and containing 540 digital optical sensors and 16 IceTop surface stations with 64 sensors. With the integrated AMANDA-II experiment this is the world's largest neutrino telescope in operation. The construction status of IceCube is presented along with an update on physics performance study for the detection of high energy neutrinos. The potential of the full km^3-scale telescope in the search for astrophysical sources is also addressed.
