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 …

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 …

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 …

Synchrotrons and free-electron lasers are the most powerful sources of X-ray radiation. They
constitute invaluable tools for a broad range of research; however, their dependence on …

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

Plasmas excited by laser beams or bunches of relativistic electrons have been used to
produce electric fields of 10–100 GV m− 1. This has opened up the possibility of building …

Outstanding progress has been made in high-power laser technology in the last 10 years
with laser powers reaching petawatt (PW) values. At present, there are 15 PW lasers built or …

This Letter demonstrates the transporting and focusing of laser-accelerated 14 MeV protons
by permanent magnet miniature quadrupole lenses providing field gradients of up to 500 …

We report on first commissioning results of the DRACO Petawatt ultra-short pulse laser
system implemented at the ELBE center for high power radiation sources of Helmholtz …

Phase space matching between two plasma-based accelerator (PBA) stages and between a
PBA and a traditional accelerator component is a critical issue for emittance preservation …
