Description
Dielectric Laser Accelerators (DLAs) are a promising approach for compact particle acceleration based on infrared lasers interacting with nanostructured dielectric materials. Operating at optical frequencies, these structures can sustain accelerating gradients well beyond the limits of conventional radio-frequency accelerators while enabling a drastic reduction of accelerator dimensions. Recent developments focus on extended dielectric waveguide structures supporting co-propagating electromagnetic modes synchronized with charged particle beams. This configuration enables longer interaction lengths and improved scalability compared with conventional transverse illumination schemes. This contribution presents recent advances in the design, modeling, and experimental investigation of dielectric interaction structures for particle acceleration in both sub-relativistic and relativistic regimes. Physics-based design methodologies and figures of merit for hollow-core dielectric waveguides are discussed, together with integrated beam dynamics simulations enabling co-design of electromagnetic structures and particle acceleration. This work is carried out within the European project EPITA (WP5: laser-driven acceleration) and within the INFN CSN5 iDLA project.
