Relativistic interaction of short-pulse lasers with underdense plasmas has recently led to the
emergence of a novel generation of femtosecond x-ray sources. Based on radiation from …

Laser-wakefield accelerators (LWFAs) were proposed more than three decades ago, and
while they promise to deliver compact, high energy particle accelerators, they will also …

Plasma-based accelerators use the strong electromagnetic fields that can be supported by
plasmas to accelerate charged particles to high energies. Accelerating field structures in …

Laser-driven plasma-based accelerators, which are capable of supporting fields in excess of
100 GV∕ m, are reviewed. This includes the laser wakefield accelerator, the plasma beat …

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 that a beam of x-ray radiation can be generated by simply focusing a single
high-intensity laser pulse into a gas jet. A millimeter-scale laser-produced plasma creates …

An intense laser pulse in a plasma can accelerate electrons,,, to GeV energies in
centimetres,,. Transverse betatron motion, in the plasma wake results in X-ray photons with …

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 …

Spontaneous radiation emitted from relativistic electrons undergoing betatron motion in a
plasma-focusing channel is analyzed, and applications to plasma wake-field accelerator …

This article first gives the authors' perspectives on how the field of plasma-based
acceleration (PBA) developed and how the current experiments, theory, and simulations are …
