Self Focusing of Relativistic Electron Bunches in Plasma available in PDF, EPUB and Kindle. 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.

Frontiers in High Energy Density Physics available in PDF, EPUB and Kindle. Recent scientific and technical advances have made it possible to create matter in the laboratory under conditions relevant to astrophysical systems such as supernovae and black holes. These advances will also benefit inertial confinement fusion research and the nation's nuclear weapon's program. The report describes the major research facilities on which such high energy density conditions can be achieved and lists a number of key scientific questions about high energy density physics that can be addressed by this research. Several recommendations are presented that would facilitate the development of a comprehensive strategy for realizing these research opportunities.

Coulomb Field Effect on Plasma Focusing and Wake Field Acceleration available in PDF, EPUB and Kindle. It is shown that the fields generated by relativistic electron (positron) bunches moving in overdense cold plasma have two components -- wake and Coulomb. The existence of the Coulomb component is caused by the absence of the Debay screening of the charge moving in plasma with the velocity greater than the thermal velocity of the plasma electrons. It is shown that at some conditions the contribution of the Coulomb component to focusing and self-focusing of the electron (positron) bunches, and wake field generation could be essential. This conclusion is valid for different descriptions of cold plasma-relativistic electron bunch system.

Download and read online ebook Relativistic Self Focusing of Short Pulse Radiation Beams in Plasmas write by P. Sprangle. This book was released on 1987. Relativistic Self Focusing of Short Pulse Radiation Beams in Plasmas available in PDF, EPUB and Kindle. An envelope equation is derived which describes the radial evolution of a radiation beam propagating through a plasma. The radiation envelope equation contains a defocusing term due to diffraction spreading and a focusing term due to relativistic oscillations of the plasma electrons. The case of a constant density background plasma is analyzed in detail and an expression for a critical laser power is derived. For powers exceeding the critical power the radiation envelope oscillators and does not diffract. Under certain conditions, the radiation beam propagates through the plasma with a constant radius envelope. Keywords: Self focusing; Laser plasma interactions; Radiation propagation; Envelope equation; Relativistic plasma.

Instabilities of Relativistic Electron Beam in Plasma available in PDF, EPUB and Kindle. 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.
