This study aims to achieve a quantitative understanding of the anti-mix layer’s effectiveness at preventing mid -Z intrusion into the core plasma. We investigate the effectiveness of anti-mix layer on the PSS platform using the radiation-hydrodynamics code, Ares, with a Reynolds-Averaged Navier Stokes mix model. Results are validated through comparison with experimental data of the PSS platform, which included an anti-mix layer, and are then employed to estimate the effect of a reduced and/or removed anti-mix layer on shot performance.
