Abstract

We study the bimodal imaging of neutron and x-ray simultaneous tomography in complementary ways and feasibility test for HANARO thermal neutron facility. This approach combines the advantages of x-rays, which exhibit low penetration for high atomic numbers, with neutrons that have high cross-sections for light elements such as Li, Be, and B. This combination allows for a comprehensive understanding of the internal structure of materials, extending the exploration range beyond what is possible with conventional x-ray and neutron technologies. We additionally demonstrate the correction of scattering in neutron images using black body techniques, which successfully enhances visibility and effectively reduces scattering-induced noise. Furthermore, we discuss the potential for quantitative and qualitative comparative evaluations by applying an unrolling method as a new approach to straighten bent or twisted objects. The results suggest the future applicability of neutron and x-ray simultaneous tomography at HANARO and indicate the potential for integration with quantitative techniques such as energy-selective imaging and interferometry.
