| In 1993 scientists at the Tokamak Fusion Test Reactor, at Princeton University’s plasma physics laboratory in New Jersey, produced a controlled fusion reaction, during which the temperature in the reactor surpassed three times that of the core of the sun. In a tokamak reactor, massive magnets confine hydrogen plasma under extremely high temperatures and pressures, forcing the hydrogen nuclei to fuse. When atomic nuclei are forced together in nuclear fusion, the reaction releases an extraordinary amount of energy. |
