Book Description
In recent years the significant progress in satellite-based observations of plasma states and associated electromagnetic phenomena in space has resulted in the accumulation of much evidence of various plasma instabilities. Today plasma instabilities are believed to be responsible for electromagnetic radiation as well as for many of the macroscopic dynamics of plasmas in space. Most students who begin to study plasma physics are intrigued by the unstable nature of plasmas compared with other states of matter; however, they often become frustrated because there are so many in stabilities. Such frustration explains in part why there is no textbook which treats this subject exclusively. A description of plasma instabilities in a systematic way is nontrivial and takes a pertinacious effort. This book is an attempt to provide a basic introduction on the subject and covers most of the important instabilities. However, the author must apologize for any omission of references to contributions of individuals who deserve more credit. The reader is assumed to have a general knowledge of plasma physics obtainable in an undergraduate course. The book is intended to be used as a reference text on the subject of plasma instabilities at the under graduate level as well as for a text in a special course in graduate school. Because the book is part of a series on physics and chemistry in space, emphasis is placed on plasma instabilities relevant in space plasmas.

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
In a recent letter (Physics Letters, 11:226 (1964)), we considered the effects of electron inertia on plasma stability. However, because of an inconsistency in the ordering procedure, only the resistive unstable branch of the growth rates for interchange modes, as resulting from the reported dispersion relation, was regarded as significant. Here we show that the regime where the interchange instability is only governed by electron inertia can be consistently considered, and also derive a dispersion relation from which all previous results obtained in collisional or collisionless regimes can be deduced as special cases.

Book Description
Instabilities in a Confined Plasma is entirely devoted to a theoretical exposition of the subject of plasma instabilities in confined systems. The book is an important contribution to the study of plasma instabilities, not only in fusion devices such as the Tokamak but also in astrophysical phenomena. It covers toroidal confinement systems, internal MHD modes, small-scale MHD instabilities, MHD internal kink modes, MHD modes in collisionless and neoclassical regimes, drift-MHD modes, external kink modes, and Alfven eigenmodes.

Book Description
We investigate the effects of a hot species on plasma stability in dipolar magnetic field. The results can be applied to the dipole experiments employing the electron cyclotron heating. We consider the interchange stability of a plasma of fluid background electrons and ions with a small fraction of hot kinetic electrons. The species diamagnetic drift and magnetic drift frequencies are assumed to be of the same order, and the wave frequency is assumed to be much larger than the background, but much less than the hot drift frequencies. We derive and analyze an arbitrary total pressure dispersion relation to obtain the general requirements for stability in dipolar geometry. As an application of the theory, we consider a special separable form of a point dipole equilibrium. Our analysis shows that a weak drift resonance with the slowly moving hot electrons modifies the simple Magnetohydrodynamic (MHD) interchange stability condition. Destabilization by this weak drift resonance can be avoided by carefully controlling the hot electron density and temperature profiles. A strong hot electron destabilization due to magnetic drift reversal is found not to occur in point dipole geometry.
