Description
The miniaturization of particle accelerators via Dielectric Laser Acceleration (DLA) offers a route to ultra-compact, cost-effective devices powered by commercial laser systems. This work explores the extension of DLA technology—historically focused on electrons—to protons, aiming to enable "on-chip" sources of high energy hadrons. We present the design and simulation of a novel microstructure optimized for the acceleration of non-relativistic protons. Key challenges addressed include the management of phase slippage and the requirement for strong transverse confinement of heavy particles at low $\beta$. Using high-fidelity particle tracking simulations developed in C++, we will characterize the longitudinal and transverse beam dynamics within the proposed structure. This study aims to demonstrate the potential for stable acceleration and focusing, validating the pDLA(proton-DLA)* concept as a viable candidate for future compact accelerator architectures.
