Projectile Ablation and Survival in Mass Accelerators Using High Energy Density Plasmas for Mass Acceleration

Abstract

Two theoretical methods have been developed for analyzing ablation in MAID projectile accelerators. A one-dimensional model determines the effect of shocks on the ablating layer. It resolves the boundary layer of the plasma-solid interface, and demonstrates shock formation in the plasma. A detailed physics model incorporates detailed chemistry and determines the global average properties of an experimental mass accelerator. Results of experiments are compared with simulations. Excellent agreement is found. Two-dimensional ablation effects are illustrated.
