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 …

Free-electron lasers generate high-brilliance coherent radiation at wavelengths spanning
from the infrared to the X-ray domains. The recent development of short-wavelength seeded …

Laser-plasma wakefield accelerators have seen tremendous progress, now capable of
producing quasi-monoenergetic electron beams in the GeV energy range with few …

Plasma wakefield accelerators are capable of sustaining gigavolt-per-centimeter
accelerating fields, surpassing the electric breakdown threshold in state-of-the-art …

A minimally invasive transverse beam profile monitor based on supersonic gas curtain
technology and beam-induced fluorescence has been developed and demonstrated. The …

We present the experimental demonstration of density downramp injection at a gas-dynamic
shock in a beam-driven plasma accelerator. The ultrashort driver electron beam with a peak …

We report on experimental investigations of plasma wave structures in a plasma wakefield
acceleration (PWFA) stage which is driven by electron beams from a preceding laser plasma …

We report on tailoring ionization-induced injection in laser wakefield acceleration so that the
electron injection process is self-truncating following the evolution of the plasma bubble …

Optical probing is an indispensable tool in research and development. In fact, it has always
been the most natural way for humankind to explore nature. However, objects consisting of …

The choice of the correct density profile is crucial in laser wakefield acceleration. In this
work, both subsonic and supersonic gas targets are characterized by means of fluid …
