The design of devices that use powerful magnetic fields to control plasma so fusion can take place. The most widely used magnetic confinement device is the tokamak, followed by the stellarator.
PRINCETON, New Jersey (June 6, 2018) – The 23rd International Conference on Plasma Surface Interactions in Controlled Fusion Devices – the preeminent biennial research conference in this field – begins on June 17 and continues for six days.

A team of U.S. and German scientists has used a system of large magnetic “trim” coils designed and delivered by the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) to achieve high performance in the latest round of experiments on the Wendelstein 7-X (W7-X) stellarator. The German machine, the world’s largest and most advanced stellarator, is being used to explore the scientific basis for fusion energy and test the suitability of the stellarator design for future fusion power plants.

Halo currents — electrical currents that flow from the hot, charged plasma that fuels fusion reactions and strike the walls of fusion facilities — could damage the walls of fusion devices like ITER, the international experiment under construction in France to demonstrate the feasibility of fusion power.

A key goal for ITER, the international fusion device under construction in France, will be to produce 10 times more power than goes into it to heat the hot, charged plasma that sustains fusion reactions. Among the steps needed to reach that goal will be controlling instabilities called “neoclassical tearing modes” that can cause magnetic islands to grow in the plasma and shut down those reactions.
You may be most familiar with the element lithium as an integral component of your smart phone’s battery, but the element also plays a role in the development of clean fusion energy. When used on tungsten surfaces in fusion devices, lithium can reduce periodic instabilities in plasma that can damage the reactor walls, scientists have found.

Throughout 2017 researchers at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) have produced new insights into the science of fusion energy that powers the sun and stars and the physics of plasma, the hot, charged state of matter that consists of electrons and atomic nuclei, or ions, and makes up 99 percent of the visible universe. The research advances the development of fusion as a safe, clean and plentiful source of power, produced in doughnut-shaped facilities called tokamaks, and explores the diverse aspects and applications of plasma.
Princeton Plasma Physics Laboratory is a U.S. Department of Energy national laboratory managed by Princeton University.
