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 …

Laser-plasma acceleration promises compact sources of high-brightness relativistic electron
beams. However, the limited stability often associated with laser-plasma acceleration has …

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

Applications of laser-plasma accelerators demand low energy spread beams and high-
efficiency operation. Achieving both requires flattening the accelerating fields by controlled …

Compact, tunable, radially symmetric focusing of electrons is critical to laser-plasma
accelerator (LPA) applications. Experiments are presented demonstrating the use of a …

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 …

By designing a structured gas density profile between the dual-stage gas jets to manipulate
electron seeding and energy chirp reversal for compressing the energy spread, we have …

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

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 …
