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 …

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 …

Charged particles accelerated by electromagnetic fields emit radiation, which must, by the
conservation of momentum, exert a recoil on the emitting particle. The force of this recoil …

Light–matter interactions driven by ultrahigh-intensity lasers have great potential to uncover
the physics associated with quantum electrodynamics (QED) processes occurring in neutron …

Abstract This Technical Design Report presents a detailed description of all aspects of the
LUXE (Laser Und XFEL Experiment), an experiment that will combine the high-quality and …

We report on a direct search for elastic photon-photon scattering using x-ray and γ photons
from a laser-plasma based experiment. A γ photon beam produced by a laser wakefield …

We describe a laser–plasma platform for photon–photon collision experiments to measure
fundamental quantum electrodynamic processes. As an example we describe using this …

We reconstruct spectra of secondary X-rays from a tunable 250–350 MeV laser wakefield
electron accelerator from single-shot X-ray depth-energy measurements in a compact (7.5× …

A high power laser was used to accelerate electrons in a laser-driven wakefield accelerator.
The high energy electrons were then used to generate an x-ray beam by passing them …

Spectrometry in radiation fields generated by high power lasers is challenging, since the
radiation is created in ultra short pulses (10-14–10-12 s) and thus standard spectrometric …
