Detecting cosmic neutrinos with the KM3NeT telescope
The KM3NeT experiment consists of a matrix of detectors distributed in the form of detection lines that capture their light. By scanning several million cubic metres of deep water, the trajectory and energy of the original neutrino can be accurately deduced.
Neutrinos are subatomic particles with no electrical charge and a mass close to zero. The energy range studied by KM3NeT corresponds to neutrinos of cosmic origin, caused by cataclysmic events such as the explosion of a star or the activity of a black hole. When a neutrino interacts with matter, a charged particle may be emitted. When it passes through water, it emits a cone of light (Cherenkov radiation). The KM3NeT experiment consists of a matrix of detectors distributed in the form of detection lines that capture this light. By scanning several million cubic metres of deep water, the trajectory and energy of the original neutrino can be accurately deduced.
