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 …

The fourth generation of synchrotron radiation sources, commonly referred to as the Free
Electron Laser (FEL), provides an intense source of brilliant X-ray beams enabling the …

Owing to their ultra-high accelerating gradients, combined with injection inside micrometer-
scale accelerating wakefield buckets, plasma-based accelerators hold great potential to …

The laser–plasma accelerator (LPA) presently provides electron beams with a typical current
of a few kA, a bunch length of a few fs, energy in the few hundred MeV to several GeV range …

Laser plasma accelerators (LPA) can sustain GeV/m accelerating fields offering outstanding
new possibilities for compact applications. The LPA beam brightness can now be …

The generation of single-cycle attosecond pulses based on Thomson scattering of terahertz
(THz) pulses is proposed. In the scheme, a high-quality relativistic electron beam, produced …

The laser invention more than fifty years ago was a major scientific revolution. Among the
different possible gain media, the Free Electron–Lasers (FEL) uses free electrons in the …

Laser-plasma accelerators (LPA) deliver relativistic electron beams with high peak current
and low emittance, with energies up to the GeV-level in only few centimetres. However, the …

The newly developed intense short wavelength light sources (from Extreme Ultra-Violet
(EUV) to X-rays) have open the path to the exploration of matter for revealing structures and …

A compact undulator-based soft X-ray radiation source furnishing the laser wakefield
electron acceleration concept is currently being developed at ELI-Beamlines in the Czech …
