Helical Core Formation and MHD Stability in ITER-Scale Plasmas with Fusion-born Alpha Particles

P. Adulsiriswad, A. Bierwage, M. Yagi

The effect of fusion-born alpha particles on the helical core (HC), a long-lived ideal saturation state of the $m/n=1/1$ kink/quasi-interchange mode, is studied in the ITER-scale h…
