2005. The first string of photomultiplier tubes was moved into place in February 2006. In September 2006 the second line was successfully connected. Lines 3, 4 and 5 were deployed at the end of 2006 and connected in January 2007. This was an important step that made Antares the biggest neutrino telescope in the Northern hemisphere (surpassing the Baikal neutrino telescope). Lines 6, 7, 8, 9, and 10 were deployed between March and early November 2007 and connected in December 2007 and January 2008. From May 2008 the detector has been running in its complete 12-line configuration. Deployment and connection of the detector are performed in cooperation with the French oceanographic institute, IFREMER, currently using the ROV Victor, and for some past operations the submarine Nautile. Experimental goals The ANTARES project complements the IceCube Neutrino Observatory in Antarctica. The detection principles of the two projects are very similar, although ANTARES only points toward the Southern Hemisphere. Thanks to its location in the Mediterranean Sea, ANTARES is more sensitive to neutrinos with energies below 100 TeV in the southern sky, a region that includes many galactic sources. ANTARES will detect neutrinos from high energy origin, particularly in the range from 1010 to 1014 electronvolts (10 GeV - 100 TeV). Over many years of operation, it may be able to produce a map of the neutrino flux from cosmic origins in the Southern Hemisphere. Of particular interest would be the detection of astrophysical point sources of neutrinos, possibly in correlation with observations in other bands (such as gamma rays sources observed by the HESS telescope in Namibia, which has a common field of view with ANTARES). Apart from this astro-particle physics aspect, the ANTARES telescope may also tackle some fundamental problems in particle physics, such as the search for dark matter in the form of neutralino annihilation in the Sun (normal solar neutrinos being outside the energy range of ANTARES) or the Galactic Center. Due to the very different methods employed, its expected sensitivity is complementary to the direct dark matter searches performed by various experiments such as DAMA, CDMS and at the LHC. Detection of neutralino signals would also confirm supersymmetry, but is not generally considered very likely at the ANTARES sensitivity level. Other possible "exotic" phenomena that could conceivably be measured by ANTARES include nuclearites or magnetic monopoles. Results The first neutrino detections were reported in Feb 2007. Using 6
