报告摘要：In this work, molecular dynamics (MD) particle simulation is combined with atomic kinetics described by a collisional-radiative (CR) model. The physical processes, such as photoionization and Auger process, are simulated during the interaction of X-ray free-electron laser with solid Fe targets. The simulation shows similar results as recent experiments at X-ray intensities up to 1020 Watts/cm2, which may be the brightest X-ray beam in the entire Universe. MD+CR simulation offers a new approach to understand such high power laser interaction with matter.
