Nuclear fusion experiment. Electron stream (horizontal blue line) being channelled along a magnetic field line in a nuclear fusion experiment. This research uses strong magnetic fields to produce controlled nuclear fusion reactions, which release large amounts of energy. Nuclear fusion, the process that occurs in the Sun, is cleaner than nuclear fission, since it doesn't produce radioactive waste. This is the Tokamak-15 thermonuclear facility at the Kurchatov Atomic Energy Institute, Moscow, Russia. Photographed in 1989.
