This report presents the conceptual design of a new European research infrastructure
EuPRAXIA. The concept has been established over the last four years in a unique …

Compared with state-of-the-art radio frequency accelerators, the gradient of laser wakefield
accelerators is 3–4 orders of magnitude higher. This is of great significance in the …

The longitudinal coherence of X-ray free-electron lasers (XFELs) in the self-amplified
spontaneous emission regime could be substantially improved if the high brightness …

We present an integrated study on the scalability and performance of particle-in-cell (PIC)
code simulations on CPU and GPU architectures of high parallelization focused on target …

We report on the experimental observation of a decreased self-injection threshold by using
laser pulses with circular polarization in laser wakefield acceleration experiments in a …

A capillary gas cell for laser wakefield acceleration was developed with the aid of three-
dimensional computational fluid dynamics simulations. The gas cell was specially designed …

In a plasma with a transverse density gradient, laser wavefront tilt develops gradually due to
phase velocity differences in different plasma densities. The wavefront tilt leads to a …

We demonstrate a simple but efficient way to optimize and improve the properties of laser-
wakefield-accelerated electron beams (e beams) based on a controllable shock-induced …

Here, we investigate the effects of laser polarization and wavelength on electron injection
dynamics in a laser wakefield accelerator. During the ionization process, electrons gain …

Novel schemes for generating ultralow emittance electron beams have been developed in
past years and promise compact particle sources with excellent beam quality suitable for …
