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.

In the field-reversed configuration (FRC) plasma, rotational instability with toroidal mode number n = 2 is known as a sole destructive MHD instability. Though an ideal FRC is unstable for higher n interchange instabilities, those have never been observed in past experiments. As a possible stabilized mechanism, self-generated toroidal rotation and its shear have been investigated experimentally.
