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 wakefield accelerators driven by multiple electron or laser pulses. Basic properties of linear and nonlinear plasma waves are discussed, as well as the trapping and acceleration of electrons in the plasma wave. Formulas are presented for the accelerating field and the energy gain in the various accelerator configurations. The propagation of the drive electron or laser beams is discussed, including limitations imposed by key instabilities and methods for optically guiding laser pulses. Recent experimental results are summarized.

A self-consistent theory of plasma response to a single laser beam is proposed. The driving pump is not viewed as invariant during its interaction with the plasmas. Its modulation by the plasmas has an obvious influence on the strength of the wakefield behind the pulse. This suggests that the compression of the low-intensity pulse by the plasmas might be a possible way to excite large-amplitude wakefield.

“…Plasma channel is an important tool for a variety of laser-plasma applications, such as laser-driven particle accelerators, [1][2][3][4][5][6][7][8] x-ray lasers, 9,10 harmonic generation, 11 and inertial confinement fusion. 12 The primary objective of creating a plasma channel is to guide radiation ͑e.g., an intense laser pulse in a laser wakefield accelerator͒ over many Rayleigh lengths.…”

Theory of laser wakes in plasma channels

Excitation of accelerating modes in transversely inhomogeneous plasma channels is considered as an initial value problem. Discrete eigenmodes are supported by plasma channels with sharp density gradients. These eigenmodes are collisionlessly damped as the gradients are smoothed. Using collisionless Landau damping as the analogy, the existence and damping of these “quasi-modes” is studied by constructing and analytically continuing the causal Green’s function of wake excitation into the lower half of the complex frequency plane. Electromagnetic nature of the plasma wakes in the channel makes their excitation nonlocal. This results in the algebraic decay of the fields with time due to phase-mixing of plasma oscillations with spatially-varying frequencies. Characteristic decay rate is given by the mixing time τm, which corresponds to the dephasing of two plasma fluid elements separated by the collisionless skin depth. For wide channels analytic expressions for the field evolution are derived. Implications for electron acceleration in plasma channels are discussed.
