Laser-wakefield accelerators (LWFAs) are high acceleration-gradient plasma-based particle
accelerators capable of producing ultra-relativistic electron beams. Within the strong …

We report on a novel, noninvasive method applying Thomson scattering to measure the
evolution of the electron beam energy inside a laser-plasma accelerator with high spatial …

The quality of electron beams produced from plasma-based accelerators, ie, normalized
brightness and energy spread, has made transformative progress in the past several …

Using a Dazzler system and tilting a compressor grating, we provide an effective way of
using the laser group delay dispersion to continuously steer the electron beam accelerated …

Laser and plasma interaction leads to several fascinating nonlinear phenomena, out of
which bubble wakefield excitation is one of the recent interests. This field is used for the …

We report on an experimental observation of the streaking of betatron x rays in a curved
laser wakefield accelerator. The streaking of the betatron x rays was realized by launching a …

We report on the deflection of laser pulses and accelerated electrons in a laser-plasma
accelerator (LPA) by the effects of laser pulse front tilt and transverse density gradients …

We explore the implications of a transverse density gradient on the performance of an
underdense plasma lens and nonlinear plasma-based accelerator. Transverse density …

We present experimental results which show a laser polarization-dependent contribution to
electron beam pointing jitter in laser wakefield accelerators (LWFAs). We develop a …

Betatron x rays from a laser wakefield accelerator provide a new avenue for high-resolution,
high-throughput radiography of solid materials. Here, we demonstrate the optimization of …
