Laser-electron Compton Interaction in Plasma Channels

Interaction of an ultrashort laser pulse and relativistic electron beam in a corrugated plasma channel.

Copropagation of a laser pulse and a relativistic electron beam in a corrugated plasma channel has been proposed for the direct laser acceleration of electrons [Palastro, Phys. Rev. E 77, 036405 (2008)]. The corrugated plasma channel allows for the guiding of laser pulses composed of subluminal spatial harmonics. Phase matching between the electron beam and the spatial harmonics results in acce...

Developments of electron and proton acceleration using Laser-plasma Interaction

With the development in ultra-short, ultra-intense laser technology, the potential of inventing novel table-size charged particle accelerators using laser-plasma interaction has attracted a lot of attentions due to its advantages comparing to classical accelerators. The accelerators have broad application aspects, such as medical imaging, cancer therapy, fast ignition in inertial fusion, and pr...

Self-Fields Effects on Gain in a Helical Wiggler Free Electron Laser with Ion-Channel Guiding and Axial Magnetic Field

In this paper, we have investigated the effects of self-fields on gain in a helical wiggler free electron laser with axial magnetic field and ion-channel guiding. The self-electric and self-magnetic fields of a relativistic electron beam passing through a helical wiggler are analyzed. The electron trajectories and the small signal gain are derived. Numerical investigation is shown that for grou...

Effect of the Laser Contrast Ratio within Picosecond Timescales on Generating a High-Quality Electron Beam by Laser–Plasma Interaction

High quality electron beams produced by laser plasma accelerators, in the bubble regime or in the colliding laser pulse regime, have properties of interest for many applications in fields such as material science, medicine, and chemistry. We present shortly the principle of laser plasma accelerators and we show why these beams are of interest for radiography and radiotherapy.
