The neutron tomographic data and the corresponding reconstructed 3D objects are presented here as open data in the form of GIF files. These data were used for the presentation of the first tomographic experiments using thermal monochromatic neutrons in the Laboratory of Neutron Physics of the Nuclear Physics Institute in Rez near Prague. These results were presented at the 17th international conference Correlation Optics 2025 as a talk, additionally as a student lecture, and the corresponding paper was published in the conference proceedings publication (DOI: 10.1117/12.3092695) with open access (CC BY licence). The first preprint is part of this record (file: ProcSPIE_imaging_final.pdf). The data were taken using a neutron camera constructed and provided by colleagues from MLZ neutron scattering laboratory (Garching by Munchen). Details about the measurements and the data can be found in the paper. These data are available for download and use as open-access data from the publication at SPIE library here.
