The effect of nonlinearity on plasma wake wave excited by a relativistic cylindrical charged bunch is investigated. It is shown that owing to the nonlinearity the amplitude of wake wave gets modulated in the longitudinal direction. The nonlinear wavelength in the excited field changes in the transverse direction with the result that the phase front is distorted and a turbulence developed. The nonlinear phase front distortion may be compensated by radial change of unperturbed plasma density.

Magnetic field of a relativistic nonlinear plasma wave

Longitudinal and transverse behavior of the magnetic field of a relativistic nonlinear three-dimensional plasma wave is investigated. It is shown that the magnetic field of the wave is different from

Simulation of the excitation of quasi-plane wake waves in a plasma by a resonant sequence of laser pulses with a variable envelope

Results are presented from full-scale numerical simulations of the excitation of wake waves by a sequence of weakly relativistic laser pulses in a subcritical plasma. Computations were carried out



Nonlinear plasma dynamics in the plasma wake-field accelerator.

It is shown, by analytical solutions of the one-dimensional relativistic fluid equations, that under certain conditions on the relative electron beam and plasma densities extremely large longitudinal electric fields can be generated in the beam's wake.

One-dimensional nonlinear wake fields excited in a cold plasma by charged bunches

One-dimensional nonlinear plasma wake fields excited by a single bunch and by a series of bunches are considered. The essential differences between the negatively-charged bunch case and the

Overview of plasma-based accelerator concepts

An overview is given of the physics issues relevant to the plasma wakefield accelerator, the plasma beat-wave accelerator, the laser wakefield accelerator, including the self-modulated regime, and

Simulation of ultrarelativistic beam dynamics in plasma wake-field accelerator

To study the long-term dynamics of ultrarelativistic particle beams (drivers) in a plasma wake-field accelerator, a two-dimensional hybrid code, LCODE, has been developed, in which the plasma is
