NEUTRINO Team

The messenger of the two infinities

They can pass right through the Earth without interacting. Neutrinos, the elementary particles of matter, are everywhere but almost elusive

Almost elusive

The mission of the Neutrino team is to detect these "small neutrals" in all their forms, in order to probe the great mysteries of the Universe, from the infinitely small to the great astrophysical objects.

64 billion neutrinos pass through your thumbnail every second

Capturing the elusive

3 major projects today

Our research activities are mainly linked to the study of the properties of neutrinos (ν) produced by nuclear facilities (JUNO), the detection of neutrinos emitted by astrophysical sources (KM3NeT and JUNO), and the research and development of innovative new detection concepts (LiquidO). All this work is being carried out as part of national and international national and international collaborations supported by IN2P3.

KM3NeT: 20,000 leagues under the sea

des DOMs

Located in France and Italy, the Kilometer Cube Neutrino Telescope is in fact a gigantic array of 2 detectors, comprising nearly 200,000 photomultipliers arranged in lines 200 and 700 metres high, immersed at depths of 2,500 and 3,500 metres in the Mediterranean.

This enormous size is essential to detect the very small number of ultra-high energy neutrinos coming from astrophysical sources and to trace the emission mechanisms in these sources.

The neutrino becomes a cosmic message with which we hope to probe the violent Universe...

LiquidO: even Jules Verne didn't think of that

Rather than the transparent media used since the 1950s, LiquidO works with a highly opaque liquid, in which the light produced by the interaction of neutrinos remains trapped in a very small area. By meshing this liquid very finely with optical fibres, we can improve the precision of the location of the neutrinos. interaction and the measurement of neutrino properties.

UNO: Journey to the centre of the Earth

JUNO (Jiangmen Underground Neutrino Observatory) is a neutrino detector located 53 km from the Yangjiang and Taishan nuclear power stations in China, in a tunnel 700 m below the surface. It consists of a 35.4 m diameter acrylic sphere filled with 20,000 tonnes of scintillating liquid. The sphere is surrounded by 42,000 photomultipliers and is immersed in a pool of instrumented water.

JUNO workers outside the sphere

JUNO is a versatile experiment. By studying how various families of neutrinos intermingle, it tackles fundamental physical questions such as the origin of the mass of elementary particles. Thanks to its design and very large detection volume, JUNO is also an observatory for neutrinos from supernovae, geo-neutrinos and the search for exotic neutrinos.
