Pilot attempt of the neutron microtomography of voids in gold carried out using the Neutron Microscope instrument is presented in the paper. The paper demonstrates that neutron microtomography provides viable alternative to X-ray imaging for the assessment of porosity in high atomic number materials. The model sample based on gold with artificially induced void system reveals segmented porosity with 5.4 micrometres voxel size and the spatial resolution close to 10 micrometres.

本文介绍了使用中子显微镜仪器对金中的孔隙进行中子显微断层扫描的初步尝试。该论文表明，中子显微断层扫描为评估高原子序数材料中的孔隙率提供了一种可行的替代X射线成像的方法。基于金并带有人工诱导孔隙系统的模型样品显示出体素尺寸为5.4微米且空间分辨率接近10微米的分段孔隙率。
