Collimation and acceleration of mono-energetic electron beams in Laser Plasma accelerators

TL;DR

This paper proposes a simple mechanism for producing highly collimated, quasi-monochromatic electron beams in laser plasma accelerators, achieving low divergence and significant energy gain through Compton scattering with virtual photons.

Contribution

It introduces a novel approach based on Compton scattering to enhance beam collimation and energy gain in laser plasma accelerators.

Findings

Beam divergence less than 3 mrad

Energy gain of approximately 1 GeV/cm

Generation of quasi-monochromatic electron beams

Abstract

Motivated by rapid advances in plasma based accelerators, we propose a simple mechanism for the production of highly collimated quasi monochromatic electrons beams. By considering Compton scattering of electrons (in the plasma) with virtual photons -- through an effective interaction --- we demonstrate angular collimation with a divergence less than 3 mrad quasi mono-energetic nature of the beam and an energy gain of O (1 GeV/cm), in laser induced accelerators.
