Nuclear fusion, the same reaction that fuels the sun, holds the potential for providing humankind with a clean and limitless supply of energy. To reign in the awesome power of this reaction, numerous research teams throughout the world seek to produce fusion in a controlled manner. They create miniature "suns" made of hot and dense plasma, a charged gas consisting of free electrons and positive ions. No one, however, has yet succeeded in coercing the plasma's atomic nuclei into fusing. One of the problems has been the difficulty of systematically studying the plasma, whose temperatures reach millions of degrees.
