    Notes: Acceleration and heating of a relativistic electron beam by cascading nonlinear Landau damping involving three or four intense electromagnetic waves in a plasma are studied theoretically based on kinetic wave equations and transport equations derived from relativistic Vlasov–Maxwell equations. Three or four electromagnetic waves excite successively two or three nonresonant beat-wave-driven relativistic electron plasma waves with a phase velocity near the speed of light [vp=c(1−γ−2p)1/2, γp=ω/ωpe]. Three beat waves interact nonlinearly with the electron beam and accelerate it to a highly relativistic energy γpmec2 more effectively than by the usual nonlinear Landau damping of two electromagnetic waves. It is proved that the electron beam can be accelerated to more highly relativistic energy in the plasma whose electron density decreases temporally with an appropriate rate because of the temporal increase of γp. © 1996 American Institute of Physics.

    Electron beam acceleration by nonresonantly driven relativistic electron plasma waves (1994)

    Notes: Acceleration and heating of a relativistic electron beam induced by nonlinear Landau damping of intense electromagnetic waves in a plasma are investigated theoretically based on kinetic wave equations and momentum-space diffusion equations derived from relativistic Vlasov–Maxwell equations. Two electromagnetic waves excite nonresonantly a beat-wave driven relativistic electron plasma wave with a phase velocity near the speed of light [vp=c(1−γ−2p)1/2, γp=ω/ωpe]. This wave interacts nonlinearly with the electron beam and accelerates effectively it to a highly relativistic energy γpmec2. When the beat-wave frequency equals the electron plasma frequency, the beam acceleration and the beat-wave energy density become maximum, and they are equal to those by stimulated Raman scattering.

    Electron beam acceleration by Compton scattering of extraordinary waves (1999)
    [S.l.] : American Institute of Physics (AIP)

    Topics: Physics
    Notes: Acceleration and heating of a high-energy or relativistic electron beam due to Compton scattering induced by nonlinear Landau damping of almost perpendicularly propagating extraordinary waves are investigated theoretically based on kinetic wave equations and transport equations derived from Vlasov–Maxwell equations. The numerical analysis of nonlinear wave–particle coupling coefficients in these equations has shown that the electron beam can be accelerated efficiently to the phase velocity of the beat wave near the speed of light by Compton scattering of two extraordinary waves with almost the same frequencies. The acceleration or deceleration of the electron beam occurs in accordance with whether the phase velocity of the beat wave is slightly larger or smaller than the velocity of the electron beam, respectively. For the frequencies of two waves lower than the upper-hybrid frequency (ω(approximately-less-than)ωh), or for those exceeding the right-hand cutoff frequency (ω(approximately-greater-than)ωR), the acceleration and deceleration of the electron beam become significantly strong. © 1999 American Institute of Physics.

    Nonlinear wave–particle scattering and absorption of electromagnetic and electrostatic waves in a magnetized plasma (1993)
    New York, NY : American Institute of Physics (AIP)

    Notes: Nonlinear wave–particle scattering and absorption (nonlinear Landau and cyclotron damping) of electromagnetic and electrostatic waves by high energy or relativistic electrons in a homogeneous magnetized plasma are investigated theoretically by numerical analysis of general and simplified expressions of nonlinear wave–particle coupling coefficients. It is shown that strong nonlinear absorption of the extraordinary wave can occur by nonlinear scattering into the other extraordinary waves or Bernstein waves induced by high-energy stationary or drifting electrons, and they can be accelerated. Nonlinear absorption by Bernstein wave or ordinary wave is weaker than that by extraordinary wave. These nonlinear absorption mechanisms can compete with linear absorption in a fusion plasma, and can exceed it for a sufficiently small k(parallel)ρb. It is verified that nonlinear scattering of extraordinary waves can induce the effective acceleration of relativistic electrons in a fusion plasma.

    Electron beam acceleration by nonlinear Landau damping of electromagnetic waves in a plasma (1993)

    Notes: Acceleration and heating of an electron beam caused by nonlinear Landau damping of intense electromagnetic waves in a plasma are investigated theoretically based on a velocity-space diffusion equation. The beat wave, which does not satisfy the dispersion relation, is excited by the nonlinear interaction of two electromagnetic waves and interacts nonlinearly with the electron beam. As the frequency of the beat wave approaches the electron plasma frequency, the rates of acceleration and heating of the electron beam and the beat wave energy density become maximum values, being equal to those by stimulated Raman scattering. The beat wave is an electrostatic mode that can have a phase velocity near the light velocity and is able to accelerate the electron beam to a relativistic energy.

    Ion heating by nonlinear Landau damping of ion Bernstein waves (1987)
    [S.l.] : American Institute of Physics (AIP)

    ISSN: 1089-7666

    Topics: Physics
    Notes: It is shown theoretically that efficient ion heating occurs by nonlinear Landau damping because of the self-interaction of ion Bernstein waves, where heating efficiency, nonlinear damping of ion Bernstein waves, nonlinear wave–particle coupling coefficients, and virtual waves have sharp maxima at ω(approximately-equal-to)(m/2)ωci (m=3,5,7). Ion heating depends on k(parallel)νti/ ωci and becomes significantly large for k(parallel)νti/ ωci (approximately-less-than)0.1.
