The KM3 Neutrino Telescope 2.0 (KM3NeT 2.0) is a three-sites Research Infrastructure housing the next generation neutrino telescopes. Once completed, the telescopes will have detector volumes between megaton and several cubic kilometres of clear sea water. Located in the deepest seas of the Mediterranean, KM3NeT 2.0 will open a new window on our Universe, but also contribute to the research of the properties of the elusive neutrino particles. With the ARCA telescope, KM3NeT 2.0 scientists will search for neutrinos from distant astrophysical sources such as supernovae, gamma-ray bursters or colliding stars. The ORCA telescope is the instrument for KM3NeT 2.0 scientists studying neutrino properties exploiting neutrinos generated in the Earth’s atmosphere.

Three suitable deep-sea sites are identified, namely going from west to east, KM3NeT-Fr, off-shore Toulon (France), KM3NeTIt, off-shore Portopalo di Capo Passero (Italy) and KM3NeT-Gr, off-shore Pylos (Greece). Data are continuously streamed via the public internet to the data repository and computing centres in Lyon, Bologna and in South-Italy. The administrative headquarters of the KM3NeT Research Infrastructure are located in Amsterdam, The Netherlands. The first phase of construction of the KM3NeT Research Infrastructure has begun in 2015 at the KM3NeT-It and KM3NeT-Fr site. Currently, the full configuration of KM3NeT 2.0 is partially funded. The final phase of construction of the KM3NeT Research Infrastructure will also include the KM3NeT-Gr site.
