We examine the performance of pure boron, boron carbide, high density carbon, and boron nitride ablators in the polar direct drive exploding pusher (PDXP) platform. The platform uses the polar direct drive configuration at the National Ignition Facility to drive high ion temperatures in a room temperature capsule and has potential applications for plasma physics studies and as a neutron source. The higher tensile strength of these materials compared to plastic enables a thinner ablator to support higher gas pressures, which could help optimize its performance for plasma physics experiments, while ablators containing boron enable the possibility of collecting additional data to constrain models of the platform. Applying recently developed and experimentally validated equation of state models for the boron materials, we examine the performance of these materials as ablators in 2D simulations, with particular focus on changes to the ablator and gas areal density, as well as the predicted symmetry of the inherently 2D implosion.

我们在极性直接驱动爆炸推进器（PDXP）平台中检查了纯硼，碳化硼，高密度碳和氮化硼烧蚀器的性能。该平台在国家点火设施上使用极性直接驱动配置来驱动室温胶囊中的高离子温度，并且在等离子体物理研究和作为中子源方面具有潜在的应用。与塑料相比，这些材料具有更高的拉伸强度，从而使更薄的烧蚀器能够承受更高的气压，这有助于优化其在等离子体物理实验中的性能，而含硼的烧蚀器则使得有可能收集更多数据来约束平台模型。应用最近开发并经过实验验证的硼材料状态模型方程，
