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.

Among the useful properties of a high TC superconductor (HTSC), the pinning effect included in these properties is considered effective one to reduce a plasma instability in the tokamak reactor. This is because the magnetic flux lines produced by plasma current are trapped in the pinning centers, and the trapping force reduces its motion. However, a proper operating scenario of plasma current ramp-up phase is necessary to achieve a practical stabilizing effect,
This paper proposes an operating scenario of plasma start-up for the purpose of optimizing the stabilization method of tokamak plasma by using the HTSC. The operating scenario was designed by introducing several compensation coils. According to computed results, this operating scenario has fully feasibility.
