New feedback system can improve efficiency of fusion reactions

Scientists at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) have refined the use of magnetic fields to improve the performance of doughnut-shaped fusion facilities known as tokamaks. The ...

Breakthrough brings a fusion energy device closer to realization

Scientists have achieved a remarkable breakthrough in the conceptual design of twisty stellarators, experimental magnetic facilities that could reproduce on Earth the fusion energy that powers the sun and stars. The breakthrough ...
