Book Description
The MHD equilibrium and stability limitations on the maximum pressure achievable by means of the flux-conserving tokamak concept are investigated. Stability criteria associated with ballooning effects appear to provide the most stringent limitation.

Book Description
Limitations on high-.beta. tokamaks are imposed by a number of ideal and resistive MHD instabilities. The present paper reports results on three such studies: (1) Numerical analysis using the Princeton PEST code on .beta. optimization of tokamaks for low toroidal mode numbers n; (2) analytic and numerical results on ideal ballooning modes with high n; and (3) analytic and numerical results on resistive ballooning modes at high n.

Book Description
The tokamak is the principal tool in controlled fusion research. This book acts as an introduction to the subject and a basic reference for theory, definitions, equations, and experimental results. The fourth edition has been completely revised, describing their development of tokamaks to the point of producing significant fusion power.

Book Description
Pulsed High Beta Plasmas contains the proceedings of the Third Topical Conference on High Beta Plasmas held in Oxfordshire, UK, on September 9-12, 1975. The papers explore various aspects of pulsed high beta plasmas and cover topics such as reversed field pinches; mass flow stabilization of plasma confined by helical magnetic fields; cross-field instabilities in theta-pinch plasmas; and soft X-ray emitting plasma structures during the main neutron emission of plasma foci. Experimental observations of the self-reversal of a toroidal magnetic field in pinches are also presented. This book is comprised of 98 chapters and begins with a discussion on experimental results concerning a high beta stellarator, followed by a review of toroidal theta-pinch theory. The reader is then introduced to relaxation of toroidal discharges; equilibrium and stability of a diffuse high-beta Tokamak; spectroscopic studies of high beta plasma; and pulsed radiation from focused plasmas. Subsequent chapters explore the compression and kink instabilities of reversed field pinches; self-inductance changes in a plasma focus; interactions of high-energy plasma clusters with a longitudinal magnetic field; and electromagnetic implosion of large-diameter liners. The linear theta pinch as a 14-neutron source is also described. This monograph will be a valuable source of information for physicists.

Book Description
Handbook on Plasma Instabilities, Volume 2 consists of four chapters on plasma instabilities. Chapter 14 discusses the various aspects of microinstabilities. Beam-plasma systems are covered in Chapter 15, while the various stabilization methods are presented in Chapter 16. This book concludes with deliberations on parametric effects in Chapter 17. Other topics discussed include the microinstabilities of a homogeneous unmagnetized plasma; kinetic theory of macroscopic instabilities; basic beam physics; and beam-plasma instabilities. The magnetic field configuration stabilization; macroscopic nonmagnetic stabilization methods; parametric instabilities in homogeneous unmagnetized plasmas; and parametric effects in bounded and inhomogeneous plasmas are also elaborated in this text. This publication is beneficial to students and researchers conducting work on unstable plasma.

Book Description
It is shown that use of the collisionless, rather than MHD, energy principle has little effect on the limiting .beta. for stability of a tokamak against ballooning modes.
