Book excerpt: 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.

Book Synopsis Reduced Fast Ion Transport Model For The Tokamak Transport Code TRANSP. by :
Download or read book Reduced Fast Ion Transport Model For The Tokamak Transport Code TRANSP. written by and published by . This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Integrated simulations of tokamak discharges typically rely on classical physics to model energetic particle (EP) dynamics. However, there are numerous cases in which energetic particles can suffer additional transport that is not classical in nature. Examples include transport by applied 3D magnetic perturbations and, more notably, by plasma instabilities. Focusing on the effects of instabilities, ad-hocmodels can empirically reproduce increased transport, but the choice of transport coefficients is usually somehow arbitrary. New approaches based on physics-based reduced models are being developed to address those issues in a simplified way, while retaining a more correct treatment of resonant wave-particle interactions. The kick model implemented in the tokamaktransport code TRANSP is an example of such reduced models. It includes modifications of the EP distribution by instabilities in real and velocity space, retaining correlations between transport in energy and space typical of resonant EP transport. The relevance of EP phase space modifications by instabilities is first discussed in terms of predicted fast ion distribution. Results are compared with those from a simple, ad-hoc diffusive model. It is then shown that the phase-space resolved model can also provide additional insight into important issues such as internal consistency of the simulations and mode stability through the analysis of the power exchanged between energetic particles and the instabilities.

Download or read book Iter Physics written by C Wendell Horton, Jr and published by World Scientific. This book was released on 2015-06-25 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: The promise of a vast and clean source of thermal power drove physics research for over fifty years and has finally come to collimation with the international consortium led by the European Union and Japan, with an agreement from seven countries to build a definitive test of fusion power in ITER. It happened because scientists since the Manhattan project have envisioned controlled nuclear fusion in obtaining energy with no carbon dioxide emissions and no toxic nuclear waste products.This large toroidal magnetic confinement ITER machine is described from confinement process to advanced physics of plasma-wall interactions, where pulses erupt from core plasma blistering the machine walls. Emissions from the walls reduce the core temperature which must remain ten times hotter than the 15 million degree core solar temperature to maintain ITER fusion power. The huge temperature gradient from core to wall that drives intense plasma turbulence is described in detail.Also explained are the methods designed to limit the growth of small magnetic islands, the growth of edge localized plasma plumes and the solid state physics limits of the stainless steel walls of the confinement vessel from the burning plasma. Designs of the wall coatings and the special 'exhaust pipe' for spent hot plasma are provided in two chapters. And the issues associated with high-energy neutrons — about 10 times higher than in fission reactions — and how they are managed in ITER, are detailed.
