Exploring Neutral Particle Dynamics with Fs-TALIF in Fusion Systems

Line radiation from neutral atoms and molecules is instrumental in plasma physics diagnostics. However, the rate at which they emit radiation is influenced by several factors such as plasma density, temperature, and gas density, which in our study, is hydrogen. This complexity has led to the widespread use of kinetic neutral simulations to reduce uncertainties, allowing for radiation diagnostics like fs-TALIF [1] to provide a clearer picture of plasma characteristics. The accuracy of these simulations is crucial for leveraging diagnostic tools and ensuring confidence in developing future fusion systems.
