The ANTARES Collaboration has operated from 2006 to 2022 a large area water Cherenkov detector in the deep Mediterranean Sea, optimised for the detection of muons from high-energy astrophysical neutrinos. It is located at the coordinates 42°48’N, 6°10’E (40 km off the coast of Toulon (Fr)).
ANTARES was composed of 12 detection lines, covering a surface area of 0.1 km2 : a first step toward the network of kilometric scale detectors KM3NeT, composed of ARCA (in Italy, dedicated to high energy neutrinos), and ORCA (in France, dedicated to low energy neutrinos).
