Download or read book Energetic Particles in Tokamak Plasmas written by Sergei Sharapov and published by CRC Press. This book was released on 2021-04-02 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of energetic particles in magnetic fusion plasmas is key to the development of next-generation "burning" plasma fusion experiments, such as the International Thermonuclear Experimental Reactor (ITER) and the Demonstration Power Station (DEMO). This book provides a comprehensive introduction and analysis of the experimental data on how fast ions behave in fusion-grade plasmas, featuring the latest ground-breaking results from world-leading machines such as the Joint European Torus (JET) and the Mega Ampere Spherical Tokamak (MAST). It also details Alfvenic instabilities, driven by energetic ions, which can cause enhanced transport of energetic ions. MHD spectroscopy of plasma via observed Alfvenic waves called "Alfvén spectroscopy" is introduced and several applications are presented. This book will be of interest to graduate students, researchers, and academics studying fusion plasma physics. Features: Provides a comprehensive overview of the field in one cohesive text, with the main physics phenomena explained qualitatively first. Authored by an authority in the field, who draws on his extensive experience of working with energetic particles in tokamak plasmas. Is suitable for extrapolating energetic particle phenomena in fusion to other plasma types, such as solar and space plasmas.

This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The stability of collisionless tearing modes is analyzed in the presence of an inhomogeneous magnetic field in fluid and gyrokinetic theories. It is shown by means of a fluid model that small scale modes, characterized by a negative stability parameter (∆'≺0), can be driven unstable due to a combination of the magnetic field and electron temperature gradients. The destabilization mechanism is identified as of the interchange type, similar to that for toroidal ETG modes. The resonant interaction between the mode and different classes of particles is studied in gyrokinetic theory. It is found that curvature and magnetic field inhomogeneity effectively change the mode stability through trapped particles. This is verified numerically with a gyrokinetic code (GKW) where the interchange-like destabilization is confirmed. Furthermore, the impact of a population of energetic particles is investigated. Linearly, using a gyrokinetic model, the particular case of energetic particle distribution presenting anisotropy in the temperature is taken into account. Non-linearly, the impact of the time evolution of the energetic particle density on the growth of magnetic islands is examined by means of a fluid model.

This book was released on 1992 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes the work done by Science Applications International Corporation to study the effects of energetic particles on the microstability of a high temperature tokamak. The effects of an energetic population on ballooning modes in a large aspect ratio, shifted circular flux surface tokamak equilibrium are investigated with the newly developed gryokinetic numerical technique. The gryokinetic equations for the background ion and electron, as well as that of the energetic population are solved directly as an initial problem. The energetic particles are modeled with a slow-down distribution in energy. It is found that the ballooning mode stability of the plasma with an energetic species of increasing concentration does not differ much from an increase in the background plasma beta, except for possible energetic particle drift resonances. This result is encouraging to the idea that energetic particles such as alphas may be used to stabilize the ballooning modes in a fusion reactor.
