Fusion Stellarator Device Efficiency Improvement Confirmed

August 19, 2021 | Leave a Comment

Max-Planck-Institut für Plasmaphysik (IPP) has now confirmed one of the most important optimization goals underlying the Wendelstein 7-X fusion device. The analysis shows that in the optimized magnetic field cage, the energy losses of the plasma are reduced in the desired way. Wendelstein 7-X is intended to prove that the disadvantages of earlier stellarators can […]

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 […]

A New Way to Build a Fusion Tokamak

November 3, 2016 | Leave a Comment

Recent computer simulations have suggested a novel method for launching the plasma without using solenoids. The simulations at the National Spherical Torus Experiment (NSTX), the major fusion facility at the U.S. Department of Energy’s Princeton Plasma Physics Laboratory (PPPL) shows the formation of distinct, current carrying magnetic structures called plasmoids that can initiate the plasma […]

A New Tool For Controlling Fusion Plasmas

November 2, 2016 | Leave a Comment

General Atomics (GA) researchers working at the firm’s DIII-D National Fusion Facility have created an important new tool for controlling fusion plasmas that are hotter than the sun in collaboration with scientists from the University of California-Irvine and Princeton Plasma Physics Laboratory. This is the second post of three that started yesterday. Energy and momentum […]

Fusion News Has a Big Week

November 1, 2016 | Leave a Comment

The American Physical Society had a major news day last Friday with noteworthy and informative presentation announcements for their annual meeting in San Jose, California. The four announcements deal with progress on measuring controlling and building plasma devices. These topics are critical to progress because plasma is very hot, usually under pressure and in high […]
