Kinetic Simulations of Ion Transport in Fusion Devices

Abstract

This thesis deals with the problem of ion confinement in thermonuclear fusion magnetic confinement devices. It is of general interest to understand via numerical simulations the ion confinement properties in complex geometries, in order to predict their behavior and maximize the performance of future fusion reactors. So this research is inscribed in the effort to develop commercial fusion. 1. Introduction 2. ISDEP 3. 3D Transport in ITER 4. Simulations of Fast Ions in Stellarators 5.
