Exploring the Universe with the ANTARES neutrino telescope

Abstract

The ANTARES Collaboration is currently constructing a large neutrino telescope in the Mediterranean sea. The telescope will use a three-dimensional array of photomultiplier tubes (PMTs) to detect the Cherenkov light emitted in sea water by neutrino-induced muons. The array of 12 strings, which hold 900 PMTs, is planned to be deployed at a depth of about 2500 m near Toulon (France), 40 km off the coast. The scientific objective of ANTARES is to detect high-energy neutrinos, which may be produced at astrophysical sources -- sites of the cosmic-ray acceleration, such as quasars, gamma-ray bursters, microquasars and supernova remnants. The objectives also include the indirect search for WIMPs by looking for neutrinos from neutralino annihilations in the centres of the Sun, the Earth and the Galaxy. In 2003 two strings have been successfully deployed and connected to the electro-optical cable, which transmitted data to shore station.
