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 …

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-driven plasma accelerators provide acceleration gradients that are three orders of
magnitude greater than those generated by conventional accelerators, offering the potential …

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 MeV x rays using an undulator and accelerator that are both
driven by the same 100-terawatt laser system. The laser pulse driving the accelerator and …

Laser-plasma accelerators are prominent candidates for driving next-generation compact
light sources, promising high-brightness, few-femtosecond x-ray pulses intrinsically …

Using quadrupole scan measurements we show laser-wakefield accelerated electrons to
have a normalized transverse emittance of 0.21-0.02+ 0.01 π mm mrad at 245 MeV. We …

A bright μm-sized source of hard synchrotron x-rays (critical energy E crit> 30 keV) based on
the betatron oscillations of laser wakefield accelerated electrons has been developed. The …

Laser-based electron sources are attracting strong interest from the conventional accelerator
community due to their unique characteristics in terms of high initial energy, low emittance …
