Unlocking fusion energy's potential? This research delves into the behavior of alpha particles within plasma, examining their distribution across the entire energy spectrum. It provides an analytical solution to the Fokker-Planck equation, shedding light on the dynamics of alpha particles crucial for sustained fusion reactions. Understanding these particles is key to optimizing energy production in fusion reactors. The study reveals that the alpha particle distribution comprises three distinct regions: a Maxwellian component, a modified slowing-down component, and a high-energy tail. It demonstrates that turbulent transport significantly impacts alpha particle distribution, potentially leading to bump-on-tail formations. Numerical solutions validate these analytical findings, offering insights into the temporal evolution of the alpha particle system, dividing it into slowing down, thermalization, and quasi-steady stages. The findings contribute significantly to understanding alpha particle behavior in fusion plasmas. This research supports the development of more efficient and stable fusion reactors. By enhancing our grasp of alpha particle dynamics, this work paves the way for optimized energy confinement and improved reactor performance, bringing sustainable fusion energy closer to reality.
