Upcoming and planned experiments combining increasingly intense lasers and energetic
particle beams will access new regimes of nonlinear, relativistic, quantum effects. This …

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 …

Abstract This Conceptual Design Report describes LUXE (Laser Und XFEL Experiment), an
experimental campaign that aims to combine the high-quality and high-energy electron …

The description of the dynamics of an electron in an external electromagnetic field of
arbitrary intensity is one of the most fundamental outstanding problems in electrodynamics …

Abstract The European Strategy Forum on Research Infrastructures (ESFRI) has selected in
2006 a proposal based on ultra-intense laser fields with intensities reaching up to 10 22–10 …

The emergence of a new era reaching beyond current state-of-the-art ultrashort and
ultraintense laser technology has been enabled by the approval of around€ 850 million …

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 …

We demonstrate the experimental feasibility of probing the fully nonperturbative regime of
quantum electrodynamics with a 100 GeV-class particle collider. By using tightly …

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 …

Brilliant X-and γ-ray sources with ultrashort duration are widely pursued in fundamental
science, industry and medicine. Compact femtosecond X-ray sources based on relativistic …
