Physicist William Tang has won a highly competitive $100,000 Global Impact Award from NVIDIA Corp., the leading producer of graphics processing units (GPUs) for carrying out artificial intelligence (AI) computing. This award was one of two presented at the NVIDIA national GPU technology conference held March 26-29 in San Jose, California.

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.

Birds do it and so do doughnut-shaped fusion facilities called “tokamaks.” But tokamak chirping— a rapidly changing frequency wave that can be far above what the human ear can detect — is hardly welcome to researchers who seek to bring the fusion that powers the sun and stars to Earth. Such chirping signals a loss of heat that can slow fusion reactions, a loss that has long puzzled scientists.

A key challenge in fusion research is maintaining the stability of the hot, charged plasma that fuels fusion reactions inside doughnut-shaped facilities called “tokamaks.” Physicists at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL), have recently found that drifting particles in the plasma, which consists of free electrons and atomic nuclei, can forestall instabilities that reduce the pressure crucial to high-performance fusion reactions inside these facilities.
