Abstract

Introduction. Fusion alpha particle losses from tokamaks with magnetic field ripple are ofgreat concern because they may lead to highly localised power peaks on the first wall components. In axisymmetric or weak-magnetic-ripple cases and in devices of low or moderate aspect ratio, guiding centre simulation is often assumed accurate enough to produce realistic wall and divertor loads. In the case of hot ions, however, transport mechanisms related to the finite Larmor radius [1] may play a significant role and affect alpha loss rate and wall load results especially in largeaspect-ratio or strongly nonaxisymmetric configurations.
