摘要：
The work presented herein develops a high-throughput ejecta source platform named HEFESTUS, the High Explosive First Ejecta Shock Test Source. The proposed design utilizes small high explosive charges (< 1g) for ease of use in experimental facilities. The platform will be used to elucidate the ejecta formation process and quantify ejecta production rates. We perform detailed continuum hydrodynamics simulations to highlight the feasibility of such a platform. We investigate the sensitivity to generate ejecta with platform geometry, mesh refinement, and materials' equations of state.
