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 computational procedure is developed to include the structure in the determination of coil current and voltage trajectories to achieve a specified equilibrium evolution and drive the required plasma current. The method uses linear optimal control about a nominal trajectory determined without structure. Control of the gross equilibrium parameters R, Z, κ, δ, and Ip is covered. The analysis is done for the Compact Ignition Tokamak. This calculation can give more realistic time histories of coil currents and voltages, necessary in the accurate design of future tokamaks.
