Description
KM3NeT is an underwater Cherenkov neutrino telescope operating in the abysses of the Mediterranean Sea. It consists of two detectors: one located at 2500m water depth, 40 km offshore South of Toulon (France), in the Ligurian Sea; the other one located at 3500m depth, 90 km offshore South East of Capo Passero (Sicily) in the Ionian Sea.
Each detector is an array of hundreds of mooring lines (detection units, DU), consisting of 18 digital optical modules. Each optical module host 31 3’’PMTs. DUs are powered and connected to shore by a network of electro-optical cables and junction boxes converging into a main electro-optical cable.
Each optical module hosts a piezoelectric acoustic sensor and a compass, each DU base is equipped with a hydrophone. The detector is complemented by special mooring lines, equipped with oceanographic sensors. Junction boxes provide connection to seabed observatories and instruments for geoscience.
We will report on successful use of KM3NeT sensors and marine infrastructures for innovative studies on oceanography, biology, and geophysics.
