Available in PDF, EPUB and Kindle. Book excerpt: This monograph, the latest in the IOP Plasma Physics Series, written by three of the most senior and internationally respected Japanese fusion scientists, presents a self-consistent picture of turbulent transport, structural formation and transitions-processes that are typical of the physics of many far from equilibrium systems such as exist in magnetically confined and inhomogeneous plasmas. The Author's view is that the plasma structure, fluctuations and turbulent transport are continually regulating each other and, in addition, that the structural formation and structural transition of plasmas are typical of the physics of far from equilibrium systems. The book presents and explains why the plasma inhomogeneity is the ordering parameter governing transport and how self-sustained fluctuations can be driven through subcritical excitation even beyond linear stability. In addition, the authors derive the non-linear gradient-flux relation with the result that asymmetry arising from the fluctuations allows mixing of the various kinds of fluxes. This emphasises the ever important role that electromagnetic fields play in inducing long range interactions, couplings and bifurcations in plasmas. To illustrate, a transport simulation of a high temperature current fusion experiment like JET-the Joint European Torus-helps us to understand various structural formations such as the H-mode. With the insight that structural formation in high temperature plasmas is fundamental to an accurate description of the basic phenomena that occur in our present cosmos, the authors provide a comprehensive account of the subject to help fusion researchers, fluid dynamicists and astrophysicists alike. The book addresses a key to understanding the age old question of what has occurred in the early stage of the our universe and what is likely to occur in the final stage of our universe.

Available in PDF, EPUB and Kindle. Book excerpt: Since the early developments of 'nonlinear science', plasma physics played a major role in its evolution: solitons, hamiltonian chaos, distinction between absolute and convective instabilities, and dynamics of coherent structures in turbulence. Understanding transport in plasmas is important for fusion devices but also for fundamental astrophysics, for fluid mechanics, for theoretical chemistry and engineering, and plasma processing in engineering.This second workshop gathered experts in plasma physics, nonlinear phenomena and mathematics. It aimed at enabling theoreticians, numericians and experimentalists in plasma turbulence to relate electromagnetic fluctuations, modes of self-organisation and transport processes. It may lead to developing new diagnostics and new methods for signal processing.

Available in PDF, EPUB and Kindle. Book excerpt: Anomalous transport is a ubiquitous phenomenon in astrophysical, geophysical and laboratory plasmas; and is a key topic in controlled nuclear fusion research. Despite its fundamental importance and ongoing research interest, a full understanding of anomalous transport in plasmas is still incomplete, due to the complexity of the nonlinear phenomena involved. Aspects in Anomalous Transport in Plasmas is the first book to systematically consider anomalous plasma transport theory and provides a unification of the many theoretical models by emphasizing interrelations between seemingly different methodologies. It is not intended as a catalogue of the vast number of plasma instabilities leading to anomalous transport; instead it chooses a number of these and emphasizes the aspects specifically due to turbulence. After a brief introduction, the microscopic theory of turbulence is discussed, including quasilinear theory and various aspects of renormalization methods, which leads to an understanding of resonance broadening, mode coupling, trajectory correlation and clumps. The second half of the book is devoted to stochiastic tramsport, using methods based on the Langevin equations and on Random Walk theory. This treatment aims at going beyond the traditional limits of weak turbulence, by introducing the recently developed method of decorrelation trajectories, and its application to electrostatic turbulence, magnetic turbulence and zonal flow generation. The final chapter includes very recent work on the nonlocal transport phenomenon.

Available in PDF, EPUB and Kindle. Book excerpt: For a few seconds with large machines, scientists and engineers have now created the fusion power of the stars in the laboratory and at the same time find the rich range of complex turbulent electromagnetic waves that transport the plasma confinement systems. The turbulent transport mechanisms created in the laboratory are explained in detail in the second edition of 'Turbulent Transport in Magnetized Plasmas' by Professor Horton.The principles and properties of the major plasma confinement machines are explored with basic physics to the extent currently understood. For the observational laws that are not understood — the empirical confinement laws — offering challenges to the next generation of plasma students and researchers — are explained in detail. An example, is the confinement regime — called the 'I-mode' — currently a hot topic — is explored.Numerous important problems and puzzles for the next generation of plasma scientists are explained. There is growing demand for new simulation codes utilizing the massively parallel computers with MPI and GPU methods. When the 20 billion dollar ITER machine is tested in the 2020ies, new theories and faster/smarter computer simulations running in near real-time control systems will be used to control the burning hydrogen plasmas.
Download or read book Turbulent Transport of Energetic Ions and Thermal Plasmas written by Shu Zhou and published by . This book was released on 2011 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: Three experiments are conducted to study the effect of the turbulent waves on the transport of fast ions and thermal plasmas. In the first experiment, strong drift wave turbulence with linear geometry is observed in the Large Plasma Device (LAPD) on density gradients produced by a plate limiter. Energetic lithium ions orbit through the turbulent region. Scans with a collimated ion analyzer and with Langmuir probes give detailed profiles of the fast ion spatial distribution and the fluctuating fields. The fast-ion transport decreases rapidly with increasing fast-ion gyroradius. Unlike the diffusive transport caused by Coulomb collisions, in this case the turbulent transport is super-diffusive. Analysis and simulation suggest that such super-diffusive transport is due to the interaction of the fast ions with the low-frequency two-dimensional electrostatic turbulence. The second experiment studies the dependence of the fast ion transport on the nature of the turbulent waves. Strong turbulent waves with cylindrical geometry are observed in the LAPD on density gradients produced by an annular obstacle. The characteristics of the fluctuations are modified by changing the plasma species from helium to neon, and by modifying the bias on the obstacle. Different spatial structure sizes and correlation lengths (Lcorr) of the wave potential fields alter the fast ion transport. The effects of electrostatic fluctuations are reduced due to gyro-averaging, which explains the difference in the fast-ion transport. A transition from super-diffusive to sub-diffusive transport is observed when the fast ion interacts with the waves for most of a wave period, which agrees with theoretical predictions. The transport of thermal plasmas under electrostatic waves is explored in the third experiment. Sheared azimuthal flow is driven at the edge of a magnetized plasma cylinder through edge biasing. Strong fluctuations of density and potential are observed at the plasma edge, accompanied by large density gradient. Edge turbulence and cross-field transport are modified by changing the bias voltage on the obstacle and the axial magnetic field strength. In cases with low V bias and large Bz, improved plasma confinement is observed, along with steeper edge density gradients. The radially sheared flow induced by E x B dramatically changes the cross-phase between density and potential fluctuations, which causes the wave-induced particle flux to reverse its direction across the shear layer and forms a transport barrier. In cases with higher bias voltage or smaller Bz large radial transport and rapid depletion of the central plasma density are observed. Two-dimensional cross-correlation measurement shows that a mode with azimuthal mode number m=1 and large radial correlation length dominates the outward transport in these cases. Linear analysis based on a two-fluid Braginskii model suggests that the fluctuations are driven by both density gradient and flow shear at the plasma edge.
