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.

Nonlinear electromagnetic waves generated due to the injection of high-power electromagnetic waves relating to an electron cyclotron resonance (ECR) are investigated in the GAMMA10 tandem-mirror fusion device and the QT-Upgrade laboratory device. In the GAMMA10 device, an electrostatic wave in the ion-cyclotron range of frequencies is observed around a west barrier region. During the barrier and plug electron cyclotron resonance heating (ECH), the nonlinear electromagnetic waves with the interval of the frequency corresponding to the electrostatic fluctuation are radiated from the plug region. In the QT-Upgrade laboratory device, on the other hand, the injected microwave nonlinearly interacts with an electrostatic drift-wave instability. These results in the GAMMA10 and the QT-Upgrade devices indicate the radiation of the electromagnetic waves originating from the parametric instability.
