In a significant breakthrough, researchers in the United States have demonstrated a novel method of sustaining electrical currents in nuclear fusion experiments with the successful use of a “helicon current drive.”
The advancement could help overcome a major obstacle in the quest to develop reactors that can operate continuously, according to new findings that appeared in the journal Physical Review Letters.
Achieved by a team of scientists at General Atomics in San Diego, the achievement relies on the use of powerful radio waves to drive electrical currents through extremely hot plasma, the electrically charged gas in which fusion reactions take place.
