A key issue for the development of fusion energy to generate electricity is the ability to confine the superhot, charged plasma gas that fuels fusion reactions in magnetic devices called tokamaks. This gas is subject to instabilities that cause it to leak from the magnetic fields and halt fusion reactions.

A multinational team led by Chinese researchers in collaboration with U.S. and European partners has successfully demonstrated a novel technique for suppressing instabilities that can cut short the life of controlled fusion reactions. The team, headed by researchers at the Institute of Plasma Physics in the Chinese Academy of Sciences (ASIPP), combined the new technique with a method that the U.S. Department of Energy’s Princeton Plasma Physics Laboratory (PPPL) has developed for protecting the walls that surround the hot, charged plasma gas that fuels fusion reactions.
Princeton astrophysicist Lyman Spitzer Jr. (1914-1997) was among the 20th Century’s most visionary scientists. His major influences range from founding the Princeton Plasma Physics Laboratory (PPPL) and its quest for fusion energy, to inspiring the development of the Hubble Space Telescope and its images of the far corners of the universe.
More than 350 participants from around the world will gather in Plainsboro, N.J., on September 30 for the 66th Annual Gaseous Electronics Conference (GEC). The week-long event will bring together physicists from numerous plasma science disciplines for workshops, panels and poster sessions on topics ranging from basic research to uses for plasma in microchip etching, nano- material manufacturing and other technologies.
Dutch graduate student Jasper van Rens recently completed a three-month assignment at PPPL to study a diagnostic technique that will be crucial to the success of ITER, the huge international fusion facility under construction in France. Working with Fred Levinton and Howard Yuh of PPPL subcontractor Nova Photonics, Van Rens investigated the impact of reflected light on the ITER Motional Stark Effect (MSE) instrument, which measures the internal magnetic configuration of fusion plasmas.
Leading experts from around the world gathered at the U.S. Department of Energy’s Princeton Plasma Physics Laboratory (PPPL) in July to focus on a key issue for the development of fusion energy: Improving ways to predict and mitigate disruptions that can destroy magnetically confined plasmas that are needed for fusion reactions.
Rich Hawryluk served as Deputy Director-General for the ITER Organization and Director of the ITER Administration Department. ITER is an international fusion experiment that is under construction in France. Hawryluk, a former deputy director of PPPL, completed a two-year assignment at ITER in April, 2013.
