KM3NeT

The Cubic Kilometre Neutrino Telescope, or KM3NeT, is a European research infrastructure located at the bottom of the Mediterranean Sea. It hosts water Cherenkov neutrino telescopes designed to detect and study neutrinos from distant astrophysical sources as well as from our own atmosphere, contributing significantly to both astrophysics and particle physics knowledge.

Arrays of thousands of optical sensor modules detect the faint Cherenkov light in the deep sea from charged particles originating from interactions of neutrinos in water or rock in the vicinity of the detector. The position and direction of the optical modules and the time of arrival of the light on the photomultipliers inside are recorded with high precision. Properties of the particles, like their trajectory and energy, are reconstructed from these measurements.
