Book Description
TO THE SECOND EDITION In the nine years since this book was first written, rapid progress has been made scientifically in nuclear fusion, space physics, and nonlinear plasma theory. At the same time, the energy shortage on the one hand and the exploration of Jupiter and Saturn on the other have increased the national awareness of the important applications of plasma physics to energy production and to the understanding of our space environment. In magnetic confinement fusion, this period has seen the attainment 13 of a Lawson number nTE of 2 x 10 cm -3 sec in the Alcator tokamaks at MIT; neutral-beam heating of the PL T tokamak at Princeton to KTi = 6. 5 keV; increase of average ß to 3%-5% in tokamaks at Oak Ridge and General Atomic; and the stabilization of mirror-confined plasmas at Livermore, together with injection of ion current to near field-reversal conditions in the 2XIIß device. Invention of the tandem mirror has given magnetic confinement a new and exciting dimension. New ideas have emerged, such as the compact torus, surface-field devices, and the EßT mirror-torus hybrid, and some old ideas, such as the stellarator and the reversed-field pinch, have been revived. Radiofrequency heat ing has become a new star with its promise of dc current drive. Perhaps most importantly, great progress has been made in the understanding of the MHD behavior of toroidal plasmas: tearing modes, magnetic Vll Vlll islands, and disruptions.

Book Description
Stability and Transport in Magnetic Confinement Systems provides an advanced introduction to the fields of stability and transport in tokamaks. It serves as a reference for researchers with its highly-detailed theoretical background, and contains new results in the areas of analytical nonlinear theory of transport using kinetic theory and fluid closure. The use of fluid descriptions for advanced stability and transport problems provide the reader with a better understanding of this topic. In addition, the areas of nonlinear kinetic theory and fluid closure gives the researcher the basic knowledge of a highly relevant area to the present development of transport physics.

Book Description
This book is an outgrowth of courses in plasma physics which I have taught at Kiel University for many years. During this time I have tried to convince my students that plasmas as different as gas dicharges, fusion plasmas and space plasmas can be described in a uni ed way by simple models. The challenge in teaching plasma physics is its apparent complexity. The wealth of plasma phenomena found in so diverse elds makes it quite different from atomic physics, where atomic structure, spectral lines and chemical binding can all be derived from a single equation—the Schrödinger equation. I positively accept the variety of plasmas and refrain from subdividing plasma physics into the traditional, but arti cially separated elds, of hot, cold and space plasmas. This is why I like to confront my students, and the readers of this book, with examples from so many elds. By this approach, I believe, they will be able to become discoverers who can see the commonality between a falling apple and planetary motion. As an experimentalist, I am convinced that plasma physics can be best understood from a bottom-up approach with many illustrating examples that give the students con dence in their understanding of plasma processes. The theoretical framework of plasma physics can then be introduced in several steps of re nement. In the end, the student (or reader) will see that there is something like the Schrödinger equation, namely the Vlasov-Maxwell model of plasmas, from which nearly all phenomena in collisionless plasmas can be derived.

Book Description
This revised and enlarged second edition of the popular textbook and reference contains comprehensive treatments of both the established foundations of magnetic fusion plasma physics and of the newly developing areas of active research. It concludes with a look ahead to fusion power reactors of the future. The well-established topics of fusion plasma physics -- basic plasma phenomena, Coulomb scattering, drifts of charged particles in magnetic and electric fields, plasma confinement by magnetic fields, kinetic and fluid collective plasma theories, plasma equilibria and flux surface geometry, plasma waves and instabilities, classical and neoclassical transport, plasma-materials interactions, radiation, etc. -- are fully developed from first principles through to the computational models employed in modern plasma physics. The new and emerging topics of fusion plasma physics research -- fluctuation-driven plasma transport and gyrokinetic/gyrofluid computational methodology, the physics of the divertor, neutral atom recycling and transport, impurity ion transport, the physics of the plasma edge (diffusive and non-diffusive transport, MARFEs, ELMs, the L-H transition, thermal-radiative instabilities, shear suppression of transport, velocity spin-up), etc. -- are comprehensively developed and related to the experimental evidence. Operational limits on the performance of future fusion reactors are developed from plasma physics and engineering constraints, and conceptual designs of future fusion power reactors are discussed.

Book Description
The development in plasma physics has recently been quite rapid and it is difficult to keep up with the evolution in all areas at the same time. Thus a review of the present state of plasma physics in different areas can be very useful although it is, of course, difficult to make it complete. In the present review we include basic plasma physics, laboratory and space plasmas, fusion plasmas, industrial plasmas and cosmology. Among these there are several contributions on fusion plasmas, including also a general overview of the state of nuclear fusion research. Natural starting points when discussing plasma physics are the facts that plasma is the fourth state of matter and that over 99% of the universe is in the plasma state. With this background it is somewhat surprising that plasmas are very scarce on earth and appear in natural state only in lightenings and, of course, at a distance from the earth as the ionosphere. The main application of plasma physics on earth is for the purpose of energy production but new areas like plasma processing and semiconductor plasmas are increasing in importance. The ionosphere is also of a practical importance for space crafts. In order to have a framework for understanding all these different areas of applications we need basic plasma physics including theory. A new way of understanding plasmas, which has become increasingly useful with the development of powerful computers is by kinetic simulation. Large kinetic simulations can be seen as small scale experiments with very good diagnostic possibilities. Nevertheless the understanding of large scale simulations requires advanced knowledge in statistical physics. For simulations on the transport timescale in tokamaks we still have to resort to fluid models. This makes questions of the fluid closure important. Here we have a cross diciplinary interest with Extended Irreversible Thermodynamics (EIT) used for small nanoscale systems in semiconductors. For such systems an entropy principle has been used for obtaining a fluid closure. A problem with this, for fusion plasmas, is that the entropy principle is valid only for isolated systems. This focuses the interest on the effect of external sources. External sources may, of course be of significant interest for many types of system. Philosophical aspects of external sources enter in cosmology where such sources would alter Hubble s law for the expansion of the universe. A last aspect of plasmas, also connected to the previous discussion of kinetic and fluid modes is the individual particle picture in contrast to the collective motion picture. Of course individual particle orbits are fundamental to plasma physics and to confinement in fusion systems. Nevertheless it is usually the collective aspects of many such individual orbits which dominate the dynamics in magnetic confinement. It is easy to get an intuitive feeling for collective plasma motion by looking at the discharge in a vacuum tube. It is also natural to associate the collective motion with the fluid picture. Thus in a kinetic description of collective phenomena we may think of the dynamics in terms of fluidlike bulk motion together with individual particles which are in some kind of resonance with the bulk motion. We here speak about particles which are not localized with respect to the bulk structures. An interesting, but not surprising, point is that localisation of particles in the fluid sense and in the overall confinement sense is typically provided by the same physics processes. I would like to acnowledge financial support from Chalmers University of Technology for editorial purposes, advice from the senior editorial consultant, Hans Wilhelmsson and proofreading by Hans-Georg Gustavsson.

Book Description
This graduate level textbook develops the theory of magnetically confined plasma, with the aim of bringing the reader to the level of current research in the field of thermonuclear fusion. It begins with the basic concepts of magnetic field description, plasma equilibria and stability, and goes on to derive the equations for guiding center particle motion in an equilibrium field. Topics include linear and nonlinear ideal and resistive modes and particle transport. It is of use to workers in the field of fusion both for its wide-ranging account of tokamak physics and as a kind of handbook or formulary. This edition has been extended in a number of ways. The material on mode-particle interactions has been reformulated and much new information added, including methodology for Monte Carlo implementation of mode destabilization. These results give explicit means of carrying out mode destabilization analysis, in particular for the dangerous fishbone mode. A new chapter on cyclotron motion in toroidal geometry has been added, with comparisons of the analysis of resonances using guiding center results. A new chapter on the use of lithium lined walls has been added, a promising means of lowering the complexity and cost of full scale fusion reactors. A section on nonlocal transport has been added, including an analysis of Levy flight simulations of ion transport in the reversed field pinch in Padova, RFX.

Book Description
In this new approach for a consistent transport theory in nuclear fusion processes Leslie Woods draws on over 40 years of fusion research to directly compare theoretical findings with experimental results, while taking into account recently discovered phenomena. This is thus the first book to find theoretical explanations to the sometimes-puzzling tokamak observations. Following a look at the quest for fusion power, the author goes on to examine tokamak magnetic fields and energy losses, as well as plasma flow and loop voltage. There is also a discussion of the technical constraints on the recently announced ITER design.
