Predictive modeling of Alfvén eigenmode stability in inductive scenarios in JT-60SA

Frontiers in Physics, 2023
The JT-60SA device offers unique conditions before ITER for the study of the interaction of energetic particles with plasma waves. With similar dimensions to JET, e.g., a major radius but with a slightly more elongated plasma volume, JT-60SA is used as a
