AI 中文摘要
粒子加速器的持续创新不断拓展着科学发现的前沿。激光尾场加速器有望变革科学、医学与工业领域，然而将其从实验室演示转化为可靠的实际运行，仍是长期存在的核心挑战。本文报道了一种可野外部署的系统，该系统在72小时连续运行中产生了100 MeV级、能量稳定性达1%量级的电子束，并在工业环境下为期7个月的现场试验中支持了常规全功率使用。将其应用于原位微无损检测时，该系统产生了数十MeV的轫致辐射X射线，可实现致密材料的亚50 μm空间分辨率三维显微断层成像，并能探测大型复合结构中100 μm尺度的内部缺陷，其能力超出了现有高能X射线源的水平。这些成果标志着激光尾场加速器正从实验室概念验证向科学与工业应用的实际部署过渡。
英文摘要
Successive innovations in particle accelerators have continually expanded the frontiers of scientific discovery. Laser wakefield accelerators promise to transform science, medicine, and industry, yet moving them from laboratory demonstrations to reliable real-world operation has remained a central, long-standing challenge. Here we report a field-deployable system that produced 100-MeV-class electron beams with 1%-level energy stability during 72 hours of continuous operation and supported routine full-power use throughout a seven-month field trial in an industrial setting. Applied to in situ micro-nondestructive testing, the system generated tens-of-MeV bremsstrahlung X-rays that enabled three-dimensional microtomography of dense materials at sub-50-μm spatial resolution and revealed 100-μm-scale internal defects in large composite structures, extending the capabilities beyond those of existing high-energy X-ray sources. These results mark a transition of laser wakefield acceleration from laboratory proof of concept toward practical deployment in scientific and industrial applications.
