Abstract

A novel multi-functional SAXS/WAXS/HR-XRD laboratory instrument has been developed based on a high-brightness Ga-In alloy metal-jet x-ray source, capable of producing a high-quality x-ray beam with a maximum photon flux of 7 × 108 photons/s. The system features a motorized, flexible sample stage that enables seamless switching between characterization modes. Its optical performance, including the Mo/Si multilayer ellipsoidal mirror, was validated using SHADOW4 geometric ray-tracing simulations. These simulations confirmed an 80% reflectivity at a grazing incidence angle of 1.031°, with a focal point located 2200 mm from the mirror center and a focused beam spot size of ∼1 × 0.5 mm2. In addition, comparative studies demonstrate that the platform's modular architecture offers a practical and cost-effective alternative to synchrotron facilities for routine materials characterization. Its versatile x-ray analysis capabilities support the investigation of diverse materials across multiple scientific disciplines, including biomedical sciences, materials science, and environmental research.

FusionX：液态金属喷射x射线源驱动的多功能SAXS/WAXS/HR-XRD平台。

基于高亮度Ga-In合金金属射流x射线源，研制了一种新型多功能SAXS/WAXS/HR-XRD实验仪器，能够产生最大光子通量为7 × 108光子/s的高质量x射线束。该系统具有一个机动的、灵活的样品平台，可以在表征模式之间无缝切换。利用SHADOW4几何射线追踪模拟验证了其光学性能，包括Mo/Si多层椭球镜。这些模拟证实了在掠射入射角为1.031°时的80%反射率，焦点位于距反射镜中心2200 mm处，聚焦光斑尺寸为~ 1 × 0.5 mm2。此外，比较研究表明，该平台的模块化架构为常规材料表征提供了同步加速器设施的实用且经济高效的替代方案。其多功能x射线分析功能支持跨多个科学学科的各种材料的研究，包括生物医学科学，材料科学和环境研究。
