Wave-optics simulation software for synchrotron radiation from 4th generation storage rings based on a coherent modes...

Area of Science:

• Physics
• Materials Science
• Optics

Background:

• Advancements in 4th-generation storage rings have increased the coherence of synchrotron radiation.
• Enhanced coherence enables sophisticated techniques like coherent X-ray diffraction imaging (CXDI) and X-ray photon correlation spectroscopy.
• Designing coherent beamlines requires precise simulation tools.

Purpose of the Study:

• To develop wave optics simulation software for coherent beamlines at the High Energy Photon Source (HEPS).
• To validate the software's performance through simulations and experimental application.
• To provide an open-source tool for the scientific community.

Main Methods:

• Developed the Coherence Analysis Toolbox based on coherent modes decomposition.
• Implemented a wavefront propagation model within the software.
• Performed simulations of beamline performance and a CXDI experiment.

Main Results:

• The Coherence Analysis Toolbox successfully simulated beamline performance for HEPS.
• The software was applied to a coherent X-ray diffraction imaging experiment.
• The developed software is open-source and available on GitHub.

Conclusions:

• The Coherence Analysis Toolbox meets the design requirements for coherent beamlines at HEPS.
• This software facilitates the utilization of advanced coherent X-ray techniques.
• Open-source availability promotes wider adoption and development in synchrotron science.
