Researchers at the University of Texas at Austin have proposed a novel approach to tackle a persistent issue in fusion physics related to the confinement of high-energy alpha particles in stellarators. Traditional methods struggle with the non-ideal behavior of these particles, leading to energy loss and inefficiencies in reactor design. The new modeling technique offers a more accurate prediction of particle movement without needing full-orbit simulations, making it a promising advancement in developing efficient fusion reactors and overcoming barriers to sustainable fusion energy.
"Direct application of Newton's laws is too expensive. Perturbation methods commit gross errors," said lead paper author Josh Burby, who is an Assistant Professor in the UT Austin department of physics, highlighting the limitations of traditional methods for modeling particle motion in fusion energy research.
The team's new modeling approach addresses the challenge of accurately confining alpha particles in stellarators, potentially paving the way for more effective fusion reactor designs.
