Boron Powder For the Tokamak Fusion Reactor

January 22, 2020 | 1 Comment

Princeton Plasma Physics Laboratory scientists have found that sprinkling boron powder into fusion plasma could aid in harnessing the ultra-hot gas within a tokamak facility to produce heat to generate electricity without producing greenhouse gases or long-term radioactive waste. A major issue with operating the ring-shaped fusion facilities known as tokamaks is keeping the plasma […]

Tokamak Fusion Plasma Made More Stable

January 15, 2019 | Leave a Comment

Princeton Plasma Physics Laboratory (PPPL) researchers are describing a newly discovered stabilizing effect of an underappreciated 1983 finding that variations in plasma temperature can influence the growth of magnetic islands that lead to disruption of fusion plasmas.  The discovery could help scientists seeking to bring the fusion reaction that powers the sun and stars to […]

Controlling Fusion Plasma With Microwaves

November 13, 2018 | Leave a Comment

Dr. Michael Van Zeeland from General Atomics, led the research by international team that was composed of more than 30 scientists from across the globe who worked together to develop an approach to keep the fusion plasma in check. To harness fusion energy fast plasma particles can be confined by a strong magnetic field, which […]

Another Fix For Tokamak Fusion

September 12, 2018 | Leave a Comment

Princeton Plasma Physics Lab scientists have developed a new method for reducing instabilities in fusion plasmas without triggering a fresh problem. The tokamak is the longest lived effort in fusion research to create a virtually inexhaustible supply of power to generate electricity in what may be called a “star in a jar.” Here’s the tokamak […]

Understanding Found On Unstable Fusion Plasma

July 24, 2018 | Leave a Comment

The Department of Energy’s Princeton Plasma Physics Laboratory has published an article describing a simulation of the mechanism that eliminates sawtooth instabilities in fusion plasmas. Sawtooth swings, the up-and-down ripples found in everything from stock prices on Wall Street to ocean waves, occur periodically in the temperature and density of the plasma that fuels fusion […]
