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 possibility to accelerate electron beams to ultra-relativistic velocities over short
distances by using plasma-based technology holds the potential for a revolution in the field …

The X-ray free-electron laser has opened a new era for photon science, improving the X-ray
brightness by ten orders of magnitude over previously available sources. Similar to an …

A new facility named SPARC_LAB has been recently launched at the INFN National
Laboratories in Frascati, merging the potentialities of the former projects SPARC and …

On the wake of the results obtained so far at the SPARC_LAB test-facility at the Laboratori
Nazionali di Frascati (Italy), we are currently investigating the possibility to design and build …

The breakthrough provided by plasma-based accelerators enabled unprecedented
accelerating fields by boosting electron beams to gigaelectronvolt energies within a few …

Next-generation plasma-based accelerators can push electron bunches to gigaelectronvolt
energies within centimetre distances,. The plasma, excited by a driver pulse, generates …

In this paper we demonstrate experimentally the generation of attosecond soft x-ray free-
electron laser (XFEL) pulses based on a novel approach to enhanced self-amplified …

We present the experimental demonstration of a new scheme for the generation of ultrashort
pulse<? format?> trains based on free-electron-laser (FEL) emission from a multipeaked …

Ultra-short electron beams, produced through the velocity bunching compression technique,
are used to drive the SPARC linear accelerator based source, which relies on the emission …
