One of today's most challenging issues in energy physics and engineering is the utilization of nuclear fusion power which can provide a lasting energy supply on earth. In the context of designing and developing magnetic confinement fusion reactors, the behavior of high-energetic ions in tokamaks deserves careful examination in theory, experiments and simulations since these ions play a crucial role in achieving and sustaining favorable fusion conditions in the fuel plasma. Thus a burning deuterium (D)-tritium (T) plasma tends to become self-heated by fusion born alphas. Therefore the behavior of energetic alpha particles in a D-T fusion reactor, i.e. their transport and losses as well as their impact on plasma stability must be well understood. In this book we examine the trajectories and diffusion properties of fast alpha particles in a tokamak reactor. For that we employ an orbit following code using a symplectic integration algorithm which allows for accurate calculations of the ion trajectories over long time periods, even in the presence of magnetic and electric field perturbations. The investigations presented in the book are of scientific importance to fusion research.

Fast ion transport models presently implemented in the tokamak transport code TRANSP [R.J. Hawryluk, in Physics of Plasmas Close to Thermonuclear Conditions, CEC Brussels, 1, 19 (1980)] are not capturing important aspects of the physics associated with resonant transport caused by instabilities such as Toroidal Alfv en Eigenmodes (TAEs). This work describes the implementation of a fast ion transport model consistent with the basic mechanisms of resonant mode-particle interaction. The model is formulated in terms of a probability distribution function for the particle's steps in phase space, which is consistent with the MonteCarlo approach used in TRANSP. The proposed model is based on the analysis of fast ion response to TAE modes through the ORBIT code [R.B. White et al., Phys. Fluids 27, 2455 (1984)], but it can be generalized to higher frequency modes (e.g. Compressional and Global Alfv en Eigenmodes) and to other numerical codes or theories.
