Upgrading of neutron radiography/tomography facility at research reactor

W. Abd El Bar
Abstract
A state-of-the-art neutron tomography imaging system was set up at the neutron radiography beam tube at the Egypt Second Research Reactor (ETRR-2) and was successfully commissioned in 2013. This study presents a set of tomographic experiments that demonstrate a high quality tomographic image formation. A computer technique for data processing and 3D image reconstruction was used to see inside a copy module of an ancient clay article provided by the International Atomic Energy Agency (IAEA). The technique was also able to uncover tomographic imaging details of a mummified fish and provided a high resolution tomographic image of a defective fire valve.
Kurzfassung
Ein hochmodernes Neutronentomographie-Abbildungssystem wurde am Neutronenradiographie-Strahlrohr des zweiten ägyptischen Forschungsreaktors (ETRR-2) aufgebaut und 2013 erfolgreich in Betrieb genommen. Diese Studie präsentiert eine Reihe tomographischer Experimente, die die hohe Qualität der Bildgebung zeigen. Ein Computerverfahren wurde für die Datenverarbeitung und die 3D-Bildrekonstruktion verwendet um die Kopie einer antiken Tonfigur, die von der International Atomic Energy Agency (IAEA) bereitgestellt wurde, von innen zu sehen. Diese Technik wurde auch verwendet um tomographische Bilddetails eines mumifizierten Fisches sichtbar zu machen und ein hochauflösendes Bild eines defekten Brandschutzventils zu erhalten.
