Book Description
This book is devoted to the non-linear theory of the collective interaction between a modulated beam of relativistic charged particles and narrow electromagnetic and Langmuir wave packets in plasma or gas slow-wave systems. Regular oscillations excited by a relativistic beam under the conditions of Cherenkov resonance and the anomalous Doppler effect can be used to generate coherent microwave radiation and accelerate charged particles in plasma.

Handbook on Plasma Instabilities
Author: Ferdinand F. Cap
Publisher: Academic Press
ISBN: 148327098X
Category : Science
Languages : en
Pages : 575
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.

Electromagnetic Effects in Relativistic Electron Beam Plasma Interactions
Author:
Publisher:
ISBN:
Category :
Languages : en
Pages :
Book Description
Electromagnetic effects excited by intense relativistic electron beams in plasmas are investigated using a two-dimensional particle code. The simulations with dense beams show large magnetic fields excited by the Weibel instability as well as sizeable electromagnetic radiation over a significant range of frequencies. The possible relevance of beam plasma instabilities to the laser acceleration of particles is briefly discussed. 6 refs., 4 figs.

Physics of Intense Beams in Plasmas
Author: M.V Nezlin
Publisher: Routledge
ISBN: 1351424432
Category : Science
Languages : en
Pages : 336
Book Description
Physics of Intense Beams in Plasmas is a comprehensive description of the interaction between extremely intense particle beams and plasmas. The emphasis is on experimental beam-plasma physics, but the necessary theory is also explained-much of which is innovative and original. Central to the book is the discussion of beam instabilities, emphasizing their hydrodynamic nature.

Parametric Excitation of Plasma Instabilities with a Density Modulated Relativistic Electron Beam
Author: Bamandas Basu
Publisher:
ISBN:
Category : Electron beams
Languages : en
Pages : 117
Book Description
Parametric electrostatic instabilities in a non-relativistic, stationary plasma excited by a monoenergetic, relativistic electron beam with density sinusoidally modulated along the direction of the beam flow have been theoretically investigated using multiple-time-scale perturbation expansion method. The instability occurs due to resonant energy transfer from the negative energy carrying beam-synchronous mode into the positive energy plasma oscillation mode of a uniform beam-plasma system. The resonant coupling occurs in the presence of the density modulation. The linear growth rate and the width of of the unstable spectrum have been determined. It has been found that, for a given beam to plasma density ratio, there exists an upper limit to the initial beam energy for which the instabilities can be excited.

Book Description
An intense (5 x 105 Amp/cm2), relativistic (5 MeV), electron beam will be used to investigate the heating of small volumes (~5 to 10 cm3) of dense plasma (1017-- 1018 electrons/cm3) to kilovolt temperatures via the electrostatic two-stream instability.

Electromagnetic Instabilities, Filamentation, and Focussing of Relativistic Electron Beams
Author: Roswell Lee
Publisher:
ISBN:
Category :
Languages : en
Pages : 14
Book Description
The authors report nonlinear studies of the Weibel instability of a relativistic electron beam in a plasma. If (n sub b) “(n sub p), the beam splits into self-pinched filaments at density (n sub p). These filaments then recombine into a single dense beam, from which the return current is expelled. A fraction about nu/gamma of the beam energy is lost to magnetic energy, and significant plasma heating occurs. (Author).

Self Focusing of Relativistic Electron Bunches in Plasma
Author: Valery B. Krasovitskii
Publisher: Nova Publishers
ISBN: 9781600215292
Category : Science
Languages : en
Pages : 218
Book Description
This volume presents the non-linear theory of electrostatic focusing of an electron beam split into bunches under conditions when the plasma permittivity at the modulation frequency is negative and the effective Coulomb force acting on the electron bunches is reversed. Conditions for the spatial equilibrium between the bunch and plasma emission, as well as the dynamics of the formation of focussed bunches, are confirmed by solving (both analytically and numerically) the self-consistent set of equations.
