The Sudbury Neutrino Detector
The Sudbury Neutrino Detector, located deep underground in a Canadian nickel mine, was designed to study neutrinos from the Sun and other cosmic sources. By observing these elusive particles, scientists aimed to understand fundamental properties of matter and the Sun's inner workings. The detector used a large sphere of heavy water to detect neutrinos through their interactions with atomic nuclei.
