Book Description
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.

Book Description
Some effects of toroidal field ripple on energetic ion orbits in tokamaks are considered. A finite gyroradius generalization of the adiabatic orbit theory condition for ripple trapping is derived. Resonances between the cyclotron motion and the motion through the field ripple are discussed. Conditions on the magnitude of the field ripple and the gyroradius are derived, such that the phase space islands corresponding to the cyclotron resonances overlap the ripple-trapping region. The intrinsic orbit stochasticity resulting from island overlap may be described as pitch-angle scattering. The diffusion coefficient is obtained from a mapping which is derived from the equations of motion. After scattering into the ripple-trapping region of phase space, particles are lost due to guiding center drifts in the toroidal field. Applications to ions in reactor-size tokamaks are discussed.

Book Description
Dur previous volume 14 was devoted to an exposition of the topics of sensitivity analysis and uncertainty theory with its development and application in nuclear reactor physics at the heart of the discussion. In this volume, we return to our customary format as a selection of topics of current interest, authored by those working in the field. These topics range from the theoretical underpinnings of the (linear) Boltzmann transport equation to a resume of our ex pectations in what still may be thought of as twenty-first century technology, the world's fusion reactor program. In the first article of this volume, we have Protopop escu's analysis of the structure of the Boltzmann equation and its solutions for energy and space-dependent problems of an eigenvalue nature. There long has been a curious "folk history" effect in this area~ Wigner and Weinberg could de scribe it as "what was generally known was generally untrue". This account of the Boltzmann equation surely will show that a rigorous basis for our expectations of certain solutions can be well-founded on analysis. Ely Gelbard's review of the methods of determining diffusion-type parameters in complex geometries where simple diffusion theory would be welcome has required just as much rigor to determine how such modeling can be made accurate, although to a more immediate and practical purpose. The two articles can be seen as interesting contrasts, facets of the same underlying problem showing apparently different aspects of the same central core.
