Terahertz (THz) light has proven to be a fine tool to probe and control quasi-particles and
collective excitations in solids, to drive phase transitions and associated changes in material …

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 …

Laser-plasma acceleration promises compact sources of high-brightness relativistic electron
beams. However, the limited stability often associated with laser-plasma acceleration has …

Generating high-quality laser-plasma accelerated electron beams requires carefully
balancing a plethora of physical effects and is therefore challenging—both conceptually and …

A simple, efficient scheme was developed to obtain near-gigaelectronvolt electron beams
with energy spreads of few per-mille level in a single-stage laser wakefield accelerator …

Applications of laser-plasma accelerators demand low energy spread beams and high-
efficiency operation. Achieving both requires flattening the accelerating fields by controlled …

Laser-plasma wakefield accelerators have seen tremendous progress, now capable of
producing quasi-monoenergetic electron beams in the GeV energy range with few …

Femtosecond lasers are powerful in studying matter's ultrafast dynamics within femtosecond
to attosecond time scales. Drawing a three-dimensional (3D) topological map of the optical …

Plasma-based accelerators that impart energy gain as high as several GeV to electrons or
positrons within a few centimeters have engendered a new class of diagnostic techniques …

We report the generation of stable and tunable electron bunches with very low absolute
energy spread (Δ E<? format?>≈<? format?> 5 MeV) accelerated in laser wakefields via …
