KamLAND

KamLAND, short for "KAMioka Liquid scintillator Anti-Neutrino Detector," is a scientific experiment located in Japan that studies neutrinos, which are tiny, nearly massless particles produced in nuclear reactions, such as those in the Sun and nuclear reactors. By detecting neutrinos from these sources, KamLAND helps researchers understand fundamental questions about particle physics, the processes powering the Sun, and the phenomenon of neutrino oscillation, where neutrinos change identity as they travel. The experiment uses a massive underground tank filled with a special liquid that lights up when neutrinos interact, allowing scientists to study their properties and behavior.
