Latest Tokamaks Stories
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 fusion reactor operates best when the hot plasma inside it consists only of fusion fuel (hydrogen's heavy isotopes, deuterium and tritium), much as a car runs best with a clean engine.
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.
An instrument developed by researchers at the U.S. Department of Energyâ€™s Princeton Plasma Physics Laboratory (PPPL) has enabled a research team at a fusion energy experiment in China to observe--in startling detail--how a particular type of electromagnetic wave known as a radiofrequency (RF) wave affects the behavior of hot ionized gas.

Fusion plasmas in the laboratory typically reach 100 million degrees.
Physicists working on the National Spherical Torus Experiment (NSTX) at the Princeton Plasma Physics Laboratory are now one step closer to solving one of the grand challenges of magnetic fusion researchâ€”how to reduce the effect that the hot plasma has on fusion machine walls (or how to tame the plasma-material interface).
Researchers have discovered mechanisms critical to interactions between hot plasma and surfaces facing the plasma inside a thermonuclear fusion reactor, part of work aimed at developing coatings capable of withstanding the grueling conditions inside the reactors.
Igor Yevgenyevich Tamm born in Vladivostok, Russia on July 8, 1895 was a Soviet physicist and mathematician. He studied at the University of Edinburgh in 1913-1914. He then switched to Moscow State University where he graduated in 1918. He developed an approximation method for many-body physics, in 1945. He worked with Andrei Dmitrievich Sakharov to create a tomohak system based on a toroidal magnetic thermonuclear reactor, in 1958. This led to the T-3 Soviet magnetic confinement...
