A multi-km3 sized Neutrino Telescope

KM3NeT is a future European deep-sea research infrastructure hosting a new generation neutrino telescope with a volume of several cubic kilometres that - located at the bottom of the Mediterranean Sea - will open a new window on the Universe.

With the telescope scientists of KM3NeT will search for neutrinos from distant astrophysical sources such as supernovae, gamma ray bursters or colliding stars.

An array of thousands of optical sensors will detect the faint light in the deep sea from charged particles originating from collisions of the neutrinos and the Earth.

The facility will also house instrumentation for Earth and Sea sciences for long term and on-line monitoring of the deep sea environment and the sea bottom at depth of several kilometers.

A new inititative is to extend the KM3NeT Research Facility with a neutrino detector dedicated to particle physics research (see the KM3NeT Strategy document).

Nobel prize for discovery of neutrino oscillations

06/09/2015: The KM3NeT Collaboration congratulates Takaaki Kajita and Arthur B. McDonald who were awarded today the Nobel Prize in Physics 2015 "for the discovery of neutrino oscillations, which shows that neutrinos have mass". Read the press release of the Royal Swedish Academy of Sciences.

An important step for KM3NeT
27/04/2015: In the early morning of 27th April 2015, the first node of the seafloor network at the KM3NeT-Fr site was successfully installed and connected to the 40 km long electro-optical cable which connects the network to the shore station. This cable was already deployed during the December campaign of last year.
The heart of the node is an egg-shaped titanium vessel with electronics and photonics and sufficient sockets to plug in the cables coming from the many detection units to be anchored on the seabed. The first detection unit is expected to be connected later this year. More about KM3NeT-Fr...

And yet an other boost for KM3NeT
20/07/2015: On 20th July 2015, an important upgrade of the deep-sea infrastructure of KM3NeT-It was successfully concluded. During a sea campaign that started three days earlier the old termination frame at the deep sea end of the 100 km long main cable to shore was replaced by a new one and two junction boxes were installed.
This major upgrade of the seafloor network at a depth of 3500 m was necessary to allow for the installation of a large number of detection units of the KM3NeT telescope. The first detection units are expected to be connected to the new junction boxes later this year. More about KM3NeT-It...
