Heat escaping from the core of a twelve-million degree nuclear fusion plasma device was successfully contained by a snowflake-shaped magnetic field to mitigate its impact on device walls.
Fusion reactor design
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.
Researchers at a recent worldwide conference on fusion power have confirmed the surprising accuracy of a new model for predicting the size of a key barrier to fusion that a top scientist at the U.S. Department of Energy’s Princeton Plasma Physics Laboratory (PPPL) has developed. The model could serve as a starting point for overcoming the barrier.
Michael Zarnstorff had been deputy director of research at PPPL since 2009 and a physicist at PPPL since 1984. As deputy director, he oversaw physics experiments at PPPL and collaborations on fusion experiments around the world. Zarnstorff graduated from the University of Wisconsin with a Ph.D. in physics in 1984.
The U.S. Department of Energy’s Princeton Plasma Physics Laboratory (PPPL) has awarded an $800,000 contract to a Nazareth, Pa.-based magnet manufacturer that will enable the production of essential components designed for an advanced fusion experiment.
