No more zigzags: Scientists uncover mechanism that stabilizes fusion plasmas

Up-and-down ripples, swings that rise and recede like the teeth on a saw blade, are found in everything from stock prices on Wall Street to ocean waves; and they occur periodically in the temperature and density of the plasma that fuels fusion reactions in doughnut-shaped facilities called tokamaks. If the swings combine with other instabilities in the plasma they can halt the reactions. Why some plasmas are free of sawtooth gyrations has long puzzled physicists. read more
