Latest Plasma stability Stories
In a collaborative effort, researchers in the United States and the United Kingdom have developed a new technique that will help them optimize the transport barrier, or pedestal, in fusion plasmas, which will be key to increasing future fusion power performance.
Research on the Alcator C-Mod experiment at MIT has made an unexpected connection between two seemingly unrelated but important phenomena observed in tokamak plasmas: spontaneous plasma rotation and the global energy confinement of the plasma.
A key challenge in producing fusion energy is confining the plasma long enough for the ionized hydrogen to fuse and produce net power.
Tokamaks—a leading design concept for producing nuclear fusion energy—can, under certain rare fault conditions, produce beams of very energetic "runaway" electrons that have the potential to damage interior surfaces of the device.
A major upgrade to the DIII-D tokamak fusion reactor operated by General Atomics in San Diego will enable it to develop fusion plasmas that can burn indefinitely.
Researchers at the Princeton Plasma Physics Laboratory have successfully used Coaxial Helicity Injection (CHI) to generate plasma current and couple it to a conventional current generation method at the National Spherical Torus Experiment (NSTX) fusion experiment.
Experiments in RFP fusion device show higher currents lead to self-organized helical plasma.
