          Abstract

          Conservation of cultural heritage is extremely important not only from a cultural point of view, but also from a practical one. It is our duty to pass on to future generations the cultural heritage left to us by our ancestors. Wood is one of the most common materials used to generate works of art which are in a state of constant change and/or deterioration. In order to optimize the knowledge of artworks together with their conservation, it is necessary to use the most advanced scientific and technological tools. In the following paper, we will show the tomographic results which can be achieved by application of complementary techniques based on the combined use of X-ray and neutron radiography as structural probes.

          Kurzfassung

          Die Konservierung von Kulturgütern ist von großer Bedeutung nicht nur in kultureller Hinsicht, sondern auch unter praktischen Gesichtspunkten. Wir müssen uns der Aufgabe stellen, unseren Nachfahren das kulturelle Netz weiterzugeben, das uns von unseren Ahnen überliefert wurde. Das Holz, eines der gebräuchlichsten Materialien für Kunstwerke, ist einem ständigen Prozess unterworfen, der zu Veränderungen und/oder seinem Zerfall führt. Um die Kenntnis von historisch-künstlerischen Fundstücken zu optimieren und ihre Konservierung zu ermöglichen, ist die Anwendung der besten wissenschaftlichen sowie technischen Technologien unerlässlich. Im Folgenden zeigen wir einige der computertomographischen Ergebnisse, die durch Anwendung komplementärer Messtechniken bei kombinierter Verwendung von Röntgenstrahlen und Neutronen erzielt werden können.

          Roberto Triolo is full Professor at the University of Palermo, Italy for more than 30 years. He is very active in the field of neutron and X-ray scattering concerning mostly soft matters, polymers and cultural heritage. Among his many published works, the study of dynamical and structural properties of block copolymers in supercritical carbon dioxide lead in 1997 to the Green Chemistry Presidential Award. His later activities were focused on the application of neutron techniques to archaeological artifacts.

          Graziella Giambona has achieved her PhD in chemistry in 2011 and her final thesis work was on neutron tomography on archaeological samples. Her investigation were focused on objects belonging to roman shipwrecks mainly from the Mediterranean area. Another area of research is the investigation of structural modifications of treated wood with neutron and X-ray tomography.

          Dr. Fabrizio Lo Celso is currently a faculty staff member at Physics and Chemistry department at University of Palermo, Italy. He has finished his PhD in chemistry at University of Palermo in 1998, and his final work was on a computational approach to study equilibrium properties of molten salts mixtures. During his post-doc periods in Missouri (USA), Palermo (Italy) and Jülich (Germany), he has focused his attention on various scattering techniques involving both neutron and X-ray technology. Among his current interest there is the molecular dynamics on ionic liquids and polymers.

          Dr. rer. nat. Nikolay Kardjilov is responsible for the neutron tomography instrument CONRAD at HZB Helmholtz Centre Berlin for Materials and Energy, Germany. He studied physics at Sofia University, Bulgaria, where he received his MSc degree. Thereafter, he successfully completed his PhD work in the field of neutron tomography at the department of physical science at TU Munich. In 2003 he started working at HZB, where he set up a new neutron tomography instrument. His research topics are the development and application of radiographic and tomographic techniques with neutrons.

          Dr. Ing. André Hilger is currently responsible for the technical development of neutron tomography at HZB. As PhD student he worked on the research topic “Tomography with spin-polarised neutrons He studied technical physics at the University of Applied Science (TFH) Berlin, Germany. After receiving his bachelor degree he worked as a technician between 2001 and 2006 at HZB as well as at TFH. In 2006 he obtained his MSc degree at TFH.

          Dipl.-Phys. Andreas Paulke studied physics at the Technische Universität Berlin, Germany. He worked several years on the application of X-ray tomography on various fields and on the analysis of 3D data.

          Dr. rer. nat. Ingo Manke is head of the imaging group at Helmholtz Centre Berlin, Germany. He studied physics at the Freie Universität Berlin, Germany. He finished his PhD at TU Berlin, Germany in 2002 in the field of scanning nearfield microscopy. Afterwards he worked at Fraunhofer Institute for Reliability and Microintegration. Since 2003 he has worked at HZB with research interests in the development and application of radiographic and tomographic techniques with neutron and X-ray technology.
