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

The National User Facility for Advanced Accelerator Experimental Tests II (FACET-II) at
SLAC National Accelerator Laboratory expands upon the experiments conducted at FACET …

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 …

Electrical breakdown sets a limit on the kinetic energy that particles in a conventional radio-
frequency accelerator can reach. New accelerator concepts must be developed to achieve …

We report on the application of machine learning (ML) methods for predicting the
longitudinal phase space (LPS) distribution of particle accelerators. Our approach consists …

Plasma wakefield accelerators have been used to accelerate electron and positron particle
beams with gradients that are orders of magnitude larger than those achieved in …

Data-driven science and technology offer transformative tools and methods to science. This
review article highlights the latest development and progress in the interdisciplinary field of …

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 …
