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 …

Dielectric laser accelerators (DLAs) are fundamentally based on the interaction of photons
with free electrons, where energy and momentum conservation are satisfied by mediation of …

Particle accelerators represent an indispensable tool in science and industry. However, the
size and cost of conventional radio-frequency accelerators limit the utility and reach of this …

Particle accelerators are essential tools in science, hospitals and industry,,,,–. Yet their costs
and large footprint, ranging in length from metres to several kilometres, limit their use. The …

Dielectric laser acceleration is a versatile scheme to accelerate and control electrons with
the help of femtosecond laser pulses in nanophotonic structures. We demonstrate here the …

We present a gradient-based optimization strategy to design broadband grating couplers.
Using this method, we are able to reach, and often surpass, a user-specified target …

Acceleration of electrons using laser-driven dielectric microstructures is a promising
technology for the miniaturization of particle accelerators. Achieving the desired GV m^− 1 …

Abstract Gallium oxide (Ga2O3) is an emerging wide‐bandgap transparent conductive oxide
(TCO) with potential applications for high‐power optical systems. Herein, Ga2O3 fabricated …

Using an 800 nm, 45 fs pulse-front-tilted laser we demonstrate a record 315 keV energy gain
in a dual grating dielectric laser accelerator (DLA) and average accelerating gradients of …

We report on the efficacy of a novel design for dielectric laser accelerators by adding a
distributed Bragg reflector (DBR) to a dual pillar grating accelerating structure. This mimics a …
