Preliminary XFEL Experimental Simulation Platform Based On HSWAP Engine

X-ray Free Electron Laser (XFEL) plays a critical role in diagnosing dynamic compression processes in micro- and meso-scale materials. To deepen our understanding of XFEL physics and optimize facility design, a preliminary XFEL experimental simulation platform was developed based on the High-Performance Computing (HPC) Simulation Workflow Application Platform (HSWAP). HSWAP provides workflow, component, and data linkage models for XFEL experiments, enabling flexible simulation of diverse processes through modular configurations. This platform was employed to investigate X-ray diffraction (XRD) of microscale materials and phase contrast imaging (PCI) of meso-scale explosive samples. Simulation results for XRD of a metallic sample under shock loading and PCI of voids in explosive materials demonstrate the platform's ability to accurately reproduce experimental dynamics. By integrating numerical models with data analysis, the platform enhances the design of XFEL experiments and provides a foundation for interpreting diagnostic capabilities in ultrafast processes. Future work will focus on refining simulation methods for meso-scale samples using phase-field approaches and high-Z materials under shock conditions.
