Overview of plasma-based accelerator concepts
TLDR
An overview of the physics issues relevant to the plasma wakefield accelerator, the plasma beat-wave accelerator, including the self-modulated regime, and wakefield accelerators driven by multiple electron or laser pulses is given in this article.Abstract:
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.read more

TL;DR: A laser accelerator that produces electron beams with an energy spread of a few per cent, low emittance and increased energy (more than 109 electrons above 80 MeV) and opens the way for compact and tunable high-brightness sources of electrons and radiation.

Generating multi-GeV electron bunches using single stage laser wakefield acceleration in a 3D nonlinear regime

TL;DR: In this article, a phenomenological framework for laser wakefield acceleration (LWFA) in the 3D nonlinear regime was developed, in which the plasma electrons are expelled by the radiation pressure of a short pulse laser, leading to nearly complete blowout.

TL;DR: In this paper, a unified formalism is presented for the betatron radiation of trapped and accelerated electrons in the so-called bubble regime, the synchrotron radiation of laser-accelerated electrons in usual meter-scale undulators, the nonlinear Thomson scattering from relativistic electrons oscillating in an intense laser field, and the Thomson backscattered radiation of a laser beam by laser accelerated electrons.

TL;DR: In this paper, an intense electromagnetic pulse can create a weak of plasma oscillations through the action of the nonlinear ponderomotive force, and electrons trapped in the wake can be accelerated to high energy.

Spontaneously Growing Transverse Waves in a Plasma Due to an Anisotropic Velocity Distribution
TL;DR: In this article, self-excited transverse electromagnetic waves which involve only the electrons were found to exist in plasmas provided the velocity distribution is sufficiently anisotropic, and their existence and rate of growth were derived from the Boltzmam transport equation, neglecting the collision term and retaining only linear terms of the perturbation.
