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 the GAMMA10 tandem mirror, ion cyclotron range of frequency (ICRF) waves are effectively used for the plasma production and heating. Alfvén ion cyclotron (AIC) modes are spontaneously excited due to the strong heating. Stability boundary for the AIC modes is analyzed by introducing the effective mirror ratio. It is shown that the AIC modes become more unstable with smaller mirror ratio. The pitch angle scattering of the high energy ions due to the AIC mode are clearly observed.
