The dynamics of charged particles in electromagnetic fields is an essential component of
understanding the most extreme environments in our Universe. In electromagnetic fields of …

Laser-wakefield accelerators (LWFAs) were proposed more than three decades ago, and
while they promise to deliver compact, high energy particle accelerators, they will also …

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 acceleration promises compact sources of high-brightness relativistic electron
beams. However, the limited stability often associated with laser-plasma acceleration has …

Generating high-quality laser-plasma accelerated electron beams requires carefully
balancing a plethora of physical effects and is therefore challenging—both conceptually and …

Relativistic interaction of short-pulse lasers with underdense plasmas has recently led to the
emergence of a novel generation of femtosecond x-ray sources. Based on radiation from …

One of the major goals of research for laser-plasma accelerators is the realization of
compact sources of femtosecond X-rays,,. In particular, using the modest electron energies …

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 …

A simple, efficient scheme was developed to obtain near-gigaelectronvolt electron beams
with energy spreads of few per-mille level in a single-stage laser wakefield accelerator …

Applications of laser-plasma accelerators demand low energy spread beams and high-
efficiency operation. Achieving both requires flattening the accelerating fields by controlled …
