Abstract

The radial diffusion of energetic ions is studied in the presence of high-m magnetic perturbation using DCOM code. Diffusion coefficients, D, are evaluated varying ion energy and strength of magnetic perturbation. The diffusion coefficient dependency of the magnetic perturbation strength is determined to be influenced by the ion energy. In addition, the ion energy dependence of D shows that D ∝ E^1/2 in lower energy (∼10 keV) and D ∝ E^3/2 in higher energy (>10 keV) states.
