KM3NeT is a research infrastructure being installed deep in the Mediterranean Sea.
The infrastructure houses neutrino telescopes composed of arrays of thousands of optical sensors capable of seeing the weak Cerenkov light generated by the collision of neutrinos with the water of the sea depths.
KM3NeT will consist of two nodes: ORCA, off-shore of Toulon (France), and ARCA, off the coast of Portopalo (Italy).
The ORCA telescope will have a volume of some Mton and will use the neutrinos generated in the Earth’s atmosphere to study some of their fundamental properties.
The ARCA telescope, with a volume of a few cubic kilometers of sea water, by observing the highest energy neutrinos, will help us study some of the most distant and powerful astrophysical sources, such as supernova remnants, gamma-ray bursts and star collisions.
In addition, the infrastructure will host instrumentation for Earth and Sea sciences and for long-term monitoring of the marine environment at depths of several kilometers.
