Spatiotemporal Evolution of High-Density Surface Plasmas Produced by Prompt X-rays

Abstract

A major effect of prompt cold X-rays released from a high altitude nuclear detonation to a few microns of satellite surface materials is surface vaporization, ionization, and generation of high density blowoff plasma. The physics mechanisms of cold X-ray absorption by metallic and dielectric materials, formation and expansion phases of produced warm and hot dense plasmas, and their optical and electrical properties are studied using an integration of high fidelity computational models. The results provide valuable information for the basic science of cold X-ray effects on solar cell panels of satellites.
