Fusion energy: Progress, partnerships, and the path to deployment
Over the past decade, fusion energy has moved decisively from scientific aspiration toward a credible pathway to a new energy technology. Thanks to long-term federal support, we have significantly advanced our fundamental understanding of plasma physics—the behavior of the superheated gases at the heart of fusion devices. This knowledge will enable the creation and control of fusion fuel under conditions required for future power plants. Our progress is exemplified by breakthroughs at the National Ignition Facility and the Joint European Torus.

A comparative analysis of the role of various ripple-induced classical transport processes of high-energy alpha particles in International Thermonuclear Experimental Reactor (ITER)-like tokamaks is presented. It is shown that alpha particles escape from a plasma mainly because of collisional, rather than stochastic, diffusion. The poloidal distribution of the alpha wall load in ITER is determined.
