Physicists are like bees—they can cross-pollinate, taking ideas from one area and using them to develop breakthroughs in other areas. Scientists at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) have transferred a technique from one realm of plasma physics to another to enable the more efficient design of powerful magnets for doughnut-shaped fusion facilities known as tokamaks. Such magnets confine and control plasma, the fourth state of matter that makes up 99 percent of the visible universe and fuels fusion reactions.
