摘要

Laser wakefield acceleration (LWFA) is a promising method for compact particle acceleration with prospective applications in high-energy physics and medical sciences. This study compares how different plasma density profiles influence the effectiveness of LWFA. In this study, we investigate the electron acceleration dynamics in plasma structures with varying density profiles using detailed numerical simulations and theoretical studies. Generated wake potential, wakefield and energy gain are observed for the different plasma density profiles. The findings show that the wakefield, wake potential and final energy gain are strongly influenced by plasma density. Through the strategic optimization of plasma and laser parameters, including the plasma density profile and laser field parameter, it is possible to exert control over the generated wakefield and wake potential, thus maximizing the energy gain to a maximum of 393 MeV. The fundamental purpose of this research is to develop accurate correlations to improve LWFA settings, gain a better knowledge of plasma-assisted particle acceleration, and realize the untapped potential of this exciting technology.
