Spatiotemporal Evolution of High-Density Surface Plasmas Produced by Prompt X-rays
Abstract
The objective of the proposed research is to explore the physics mechanisms of prompt cold X-ray absorption by metallic and dielectric materials, formation and expansion phases of produced WDP, and its physical and electrical properties. The study of the fundamental physics of the formation and spatiotemporal evolution of WDPs is proposed using the Monte Carlo and Molecular Dynamics methods coupled with the Hartree-Fock-Slater - Collisional- Radiative Steady-State model. The proposed research is multi-disciplinary in nature, and covers the physics of photon transport, X-ray absorption by materials, formation and expansion of WDP, plasma coupling to metallic and dielectric surfaces of solar cell structures, quantum-level prediction of conductivity and electrical properties of the plasma. Assuming the presence of cold X-rays from a nuclear event, the transition from the stage of X-ray absorption to the stage of material ionization, the conditions for formation of WDP, the spatiotemporal evolution and physical properties of WDP shall be studied. This basic research covering the physical properties of WDPs generated in the cold X-ray radiation environment.
