How does super k- detect neutrinos?

Super-Kamiokande, or Super-K, detects neutrinos using a large underground tank filled with ultra-pure water. When a neutrino interacts with a water molecule, it can produce charged particles, such as electrons or muons, which emit Cherenkov radiation as they travel faster than the speed of light in water. This light is captured by an array of photomultiplier tubes lining the tank, allowing scientists to observe and analyze the interactions. By measuring the intensity and timing of the detected light, researchers can infer properties of the incoming neutrinos.
