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.

The usage of non-paraxial elements, like a “fat” mirror cell or a divertor, is one of the techniques for stabilizing plasma in axisymmetric systems. The plasma equilibrium in such elements is studied in the paper. The calculation based on the Grad-Shafranov type equation has been done for plasma equilibrium under isotropic and anisotropic pressures in the configuration with a divertor, produced with the given external currents. The inverse variable technique is used in the problem with the fixed boundary surface. This approach is used, in particular, for calculating an equilibrium in the rippled field.
