    We developed non-destructive imaging diagnostics for optimizing particle delivery in X-ray Free-Electron Laser (XFEL) experiments. This improves single-particle imaging efficiency by providing real-time feedback on particle streams.

    Area of Science:

    • X-ray science
    • Particle physics
    • Optical imaging

    Background:

    • Single-particle diffractive imaging at X-ray Free-Electron Lasers (XFELs) requires precise delivery of sub-micrometer particles to the X-ray focus.
    • Current methods for monitoring particle streams can be invasive or lack real-time feedback, impacting experimental efficiency.

    Purpose of the Study:

    • To develop and demonstrate an in-situ, non-destructive imaging diagnostic system.
    • To enable real-time optimization of particle injectors and alignment of X-ray and particle beams for single-particle imaging experiments.

    Main Methods:

    • Utilized laser illumination schemes for particle stream visualization.
    • Employed fast imaging detectors for rapid data acquisition.
    • Integrated the diagnostic system into existing XFEL experimental setups.

    Main Results:

    • Successfully demonstrated in-situ, non-destructive imaging of sub-micrometer aerosol particle streams.
    • Provided real-time feedback on particle injector performance and beam alignment.
    • Validated the diagnostic's effectiveness during diffraction measurements at the FLASH free-electron laser.

    Conclusions:

    • The developed imaging diagnostics significantly enhance the efficiency of single-particle imaging experiments by enabling non-invasive, real-time monitoring and optimization.
    • This technology reduces sample consumption and measurement time, facilitating more effective use of XFEL facilities.
