Abstract The past decade has seen tremendous progress in the production and utilization of vortex and vector laser pulses. Although both are considered as structured light beams, the vortex lasers have helical phase fronts and phase singularities, wh

The emergence of multi-petawatt laser facilities is expected to push forward the maximum energy gain that can be achieved in a single stage of a laser wakefield acceleration (LWFA) to tens of giga-electron volts, which begs the question—is it likel

Accelerator-based x-ray free-electron lasers (XFELs) are the latest addition to the revolutionary tools of discovery for the 21st century. The two major components of an XFEL are an accelerator-produced electron beam and a magnetic undulator, which t

Plasma based acceleration (PBA) is being considered for a next generation linear collider (LC). In typical PBA-LC designs, the extreme beam parameters are expected to trigger background ion motion, which can lead to longitudinally varying nonlinear f

We propose a novel positron beam loading regime in a hollow plasma channel that can efficiently accelerate e^{+} beam with a high gradient and narrow energy spread. In this regime, the e^{+} beam coincides with the drive e^{-} beam in time and space
