Recent research into the interaction between high-intensity beams (e.g. laser or charged particle beams) and surface plasmas has revealed significant potential for generating extremely strong fields for particle acceleration and radiation production. This new approach has emerged by overcoming several challenges in beam-solid interactions. It therefore holds great promise for reforming the...
Charged particles traversing carbon-based nanostructures can trigger electromagnetic (plasmonic) modes through the collective excitation of surface electron gases. This phenomenon presents a promising avenue for achieving ultra-high particle acceleration gradients. Plasmonic excitations can be explored using both analytical models and particle-based simulations. In this work, we first revisit...
Nanostructured materials composed of alternating layers of two-dimensional carbon structures and empty or low-density regions have emerged as promising targets for compact, ultra-high gradient electron acceleration via LWFA. As an intense laser pulse propagates through these gaps, the carbon atoms at their boundaries are ionized, filling the voids with high-density electron plasmas capable of...
Solid-state plasma wakefield acceleration has recently attracted attention as a novel method for achieving unprecedented ultra-high acceleration gradients on the order of 1 TV/m or beyond. In this context, recent advancements in nanofabrication techniques have opened up the possibility of creating structured plasmas with tailored properties. For instance, the utilization of carbon nanotube...
Laser wakefield acceleration (LWFA) can produce gradients of tens to hundreds of GV/m, greatly reducing accelerator size and cost. Carbon nanotube (CNT) bundles, featuring high plasma density (>10

Laser Plasma Wakefield Acceleration (LPWA) is a promising way to achieve ultra-high accelerating gradients, relying on plasma channels to guide intense laser pulses over long distances. In this study, we explore discharge plasma capillaries as a potential solution for stable laser guiding and precise control of plasma density. We start by using Computational Fluid Dynamics (CFD) simulations to...
