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 GAMMA 10, Alfvén-ion-cyclotron (AIC) waves are spontaneously excited because of the perpendicular ions heating with ion cyclotron range of frequency waves. High-energy ions are transported to axial direction with pitch angle scattering owing to the AIC waves. In the high-energy ion signal detected with a semiconductor detector, the fluctuations with the differential frequencies between discrete peaks of the AIC waves are clearly observed. Recently, a microwave reflectometer detected the AIC mode in the anchor cell. The high-energy ions signal in the axial direction also increases when the AIC mode is excited.
