Progress toward a Km-scale neutrino detector in the deep ocean
The best particles for observing distant objects are photons and neutrinos. Because of the neutrino`s weak interaction cross section, detectors suitable for astronomy must be very large and well shielded from cosmic rays. Eventually, a detector with the order of a square km of effective area will be needed for systematic observations of distant point sources such as active galactic nuclei. Prototype detectors are currently being developed at several sites in the ocean, at Lake Baikal, and in Antarctica. This talk summarizes the status of the projects that use the deep ocean for the detector medium and shielding: DUMAND, NESTOR and ANTARES. Technical developments will be needed for a future km-scale detector; progress on one of these, a digital electronic system, is also described.
