This work analyzes the charge state and energy loss of Ar+16 projectiles impinging on partially ionized carbon plasmas. The study combines the Cross section Model-2 (CSM-2) with hydrodynamic simulations to predict projectile charge states, plasma stopping power, and projectile energy loss under realistic plasma conditions. The model considers Non-Local Thermal Equilibrium ionization states and includes contributions from both free and bound electrons, utilizing models such as the T-Matrix, Li-Petrasso, RPA, and PLASTOP. The results demonstrate that CSM-2 provides significant improvements over semi-empirical models like Kreussler and Guskov by accurately capturing non-equilibrium dynamics. PLASTOP highlights the role of bound electron contributions in partially ionized plasmas, complementing the predictions of free electron models. Experimental validation confirms the reliability and accuracy of the proposed methodology. This framework offers a robust approach for studying ion-plasma interactions, with potential applications in fusion research, warm dense matter studies, and other extreme environments. Future work will extend this methodology to other plasma conditions and projectile species.
