Market: Scientists and students involved in thermonuclear fusion research. Thermonuclear fusion research using the confinement device tokamak represents one of the most prominent science projects in the second half of the 20th century. International Tokamak Community is now committing significant effort and funds to experiments with burning plasma, hot and dense enough to produce significant nuclear fusion reactions. The methods used to enhance tokamak performance have a profound and immediate effect on machine design. This book provides an up-to-date account of research in tokamak fusion and puts forward innovative ideas in confinement physics.

At present, the mechanism for anomalous energy transport in low-[beta] toroidal plasmas -- tokamaks and stellarators -- remains unclear, although transport by turbulent E × B velocities associated with nonlinear, fine-scale microinstabilities is a leading candidate. This article discusses basic theoretical concepts of various transport and confinement enhancement mechanisms as well as experimental ramifications which would enable one to distinguish among them and hence identify a dominant transport mechanism. While many of the predictions of fine-scale turbulence are born out by experiment, notable contradictions exist. Projections of ignition margin rest both on the scaling properties of the confinement mechanism and on the criteria for entering enhanced confinement regimes. At present, the greatest uncertainties lie with the basis for scaling confinement enhancement criteria. A series of questions, to be answered by new experimental/theoretical work, is posed to resolve these outstanding contradictions (or refute the fine-scale turbulence model) and to establish confinement enhancement criteria. 73 refs., 4 figs., 5 tabs.

Existing textbooks on plasma physics usually contain only a minor contribution devoted to plasma transport. The aim of Transport Processes in Plasmas'' is to provide a comprehensive and unified presentation of the transport theory in plasmas. This subject is of great importance in general statistical and plasma physics; moreover, it constitutes a keystone in the thermonuclear fusion programme as well as in astro- and geophysics. The subject is presented here by unified concepts, methods and notations. The contents are strongly embedded in a general framework of theoretical physics, appealing to modern Hamiltonian mechanics, kinetic theory, non-equilibrium thermodynamics, etc. The necessary concepts from these disciplines are briefly but completely explained, making the two volumes a self-contained text. Plasma transport theory can be characterised as a truly interdisciplinary activity, and several chapters are included containing the important concepts of these peripheral fields, briefly and completely. Many new features are introduced in those two volumes.

This monograph describes plasma physics for magnetic confinement of high temperature plasmas in nonaxisymmetric toroidal magnetic fields or stellarators. The techniques are aimed at controlling nuclear fusion for continuous energy production. While the focus is on the nonaxisymmetric toroidal field, or heliotron, developed at Kyoto University, the physics applies equally to other stellarators and axisymmetric tokamaks. The author covers all aspects of magnetic confinement, formation of magnetic surfaces, magnetohydrodynamic equilibrium and stability, single charged particle confinement, neoclassical transport and plasma heating. He also reviews recent experiments and the prospects for the next generation of devices.
