A team of U.S. scientists has made a surprising discovery that could help bring fusion energy, a long-hoped-for clean energy source, closer to reality. In a recent experiment at the University of ...
changes in the topology of the field by breaking and reconnecting the magnetic field lines. This process occurs in (magnetohydrodynamic) "sawtooth" oscillations in tokamak plasmas, in sun spots, and ...
