Design and status of IceCube

IceCube is a kilometer-scale high-energy neutrino detector that builds on the wealth of experience accumulated with its smaller predecessor, AMANDA. An international collaboration has begun construction of key components of the IceCube detector and deployment operations at the South Pole will begin in late 2004. derlying design of the IceCube detector and of the DAQ system are presented here, emphasizing the digital optical modules (DOMs) as the smallest discrete IceCube building block. The event reconstruction critically relies on a relative timing accuracy from DOM to DOM of a few nanoseconds over inter-DOM separations of up to 1 km.
