Abstract

The Idaho National Laboratory (INL) has implemented laboratory-based micro-X-ray computed tomography in a laboratory equipped for the examination of highly radioactive samples. This capability provides nondestructive three-dimensional volumetric information on samples to inform subsequent traditional destructive examinations as well as real-world inputs for high-fidelity scientific modeling. Samples can be imaged with spatial resolutions ranging from several hundred nm/voxel up to ~ 100 µm/voxel. The best usable spatial resolution achieved to date is 384 nm/voxel with this instrument, while the highest radiological dose rate of a sample imaged is ~ 60 R/h β/γ on contact. Advanced data analysis, including custom tomographic reconstruction and segmentation methods, have also been developed to support this capability. In addition to traditional digital X-ray radiography and tomography, this instrument is also able to visualize in situ tensile and compression testing as well as perform diffraction contrast tomography. This work describes the X-ray computed tomography post-irradiation examination capabilities at INL, as well as detailing a variety of applications this instrument has examined.

爱达荷国家实验室能源材料的实验室微x射线计算机断层扫描

爱达荷州国家实验室（INL）在一个配备了高放射性样品检查设备的实验室中实施了基于实验室的微x射线计算机断层扫描。该功能提供了样品的非破坏性三维体积信息，为后续的传统破坏性检查以及高保真科学建模提供了信息。样品可以成像的空间分辨率范围从几百纳米/体素到~ 100微米/体素。该仪器迄今为止实现的最佳可用空间分辨率为384 nm/体素，而样品成像的最高辐射剂量率为~ 60 R/h β/γ接触。先进的数据分析，包括自定义层析重建和分割方法，也被开发出来支持这种能力。除了传统的数字x射线摄影和断层扫描外，该仪器还能够可视化现场拉伸和压缩测试以及执行衍射对比断层扫描。这项工作描述了INL的x射线计算机断层扫描辐照后检查能力，以及详细介绍了该仪器已检查的各种应用。
