A Pulsed Electromagnet for Laser Wakefield Electron Acceleration Experiments

Characteristics of Electron Acceleration in a Self-modulated Laser Wakefield

Acceleration of electrons by an electron plasma wave has been of great current interest because of its much larger acceleration gradient than that of conventional rf linacs [1]. Several methods have been proposed for driving a largeamplitude fast-phase-velocity plasma wave [1]. In the Laser Wake-Field Accelerator (LWFA), an electron plasma wave is driven resonantly by a short laser pulse throug...

Simulation of laser wakefield acceleration of an ultrashort electron bunch.

The dynamics of the acceleration of a short electron bunch in a strong plasma wave excited by a laser pulse in a plasma channel is studied both analytically and numerically in slab geometry. In our simulations, a fully nonlinear, relativistic hydrodynamic description for the plasma wave is combined with particle-in-cell methods for the description of the bunch. Collective self-interactions with...

A computational investigation of the impact of aberrated Gaussian laser pulses on electron beam properties in laser-wakefield acceleration experiments

Plasma wakefield acceleration experiments at FACET II

During the past two decades of research, the ultra-relativistic beam-driven plasma wakefield accelerator (PWFA) concept has achieved many significant milestones. These include the demonstration of ultra-high gradient acceleration of electrons over meter-scale plasma accelerator structures, efficient acceleration of a narrow energy spread electron bunch at highgradients, positron acceleration us...

Plasma wakefield acceleration experiments at FACET

FACET—Facilities for Accelerator science and Experimental Test beams at SLAC—will provide high-energy-density electron and positron beams with peak currents of roughly 20 kA that will be focused down to a 10μm× 10μm transverse spot size at an energy of ∼23GeV. With FACET, the SLAC linac will support a unique program concentrating on second-generation research in plasma wakefield acceleration. T...
