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 …

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-plasma accelerators of only a centimetre's length have produced nearly
monoenergetic electron bunches with energy as high as 1 GeV. Scaling these compact …

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 …

A method, which utilizes the large difference in ionization potentials between successive
ionization states of trace atoms, for injecting electrons into a laser-driven wakefield is …

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 …

The concepts of matched-beam, self-guided laser propagation and ionization-induced
injection have been combined to accelerate electrons up to 1.45 GeV energy in a laser …

Laser wakefield acceleration of electrons holds great promise for producing ultracompact
stages of GeV scale, high-quality electron beams for applications such as x-ray free electron …

We report on near-GeV electron beam generation from an all-optical cascaded laser
wakefield accelerator (LWFA). Electron injection and acceleration are successfully …

Ionization-induced injection mechanism was introduced in 2010 to reduce the laser intensity
threshold for controllable electron trapping in laser wakefield accelerators (LWFA). However …
