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 …

Linear accelerators delivering high brightness electron beams are essential for a number of
current and proposed accelerator applications, such as free electron lasers (FELs). In this …

Ultralow emittance (≤ 20 nm, normalized) electron beams with 1 0 5 electrons per bunch
are obtained by tightly focusing an ultrafast (∼ 100 fs) laser pulse on the cathode of a 1.6 …

Electrons with a linear energy/momentum dispersion are called massless Dirac electrons
and represent the low-energy excitations in exotic materials such as graphene and …

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 production of high spectral brilliance radiation from electron beam sources depends
critically on the electron beam qualities. One must obtain very high electron beam …

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

C-band technology is emerging as an exciting innovative approach to the creation of
compact new accelerators. Besides the possibility to sustain higher gradients and higher …
