“…The tomographic analysis was carried out in a shielded laboratory for X-ray measurements at the Physics Department of the University of Turin. The instrumental apparatus was been specifically created using components already employed for other applications ( Figure 3 ): a Hamamatsu Microfocus L8121-03 X-ray source, used, for example, for the micro-CT of pearls [ 20 ]; a rotating platform of about 20 cm in diameter on which the object under analysis is placed, allowing the acquisition of multi-angle images; a Flat Panel (FP) Shad-o-Box 6K HS detector, from Teledyne Dalsa, with a single pixel size of 49.5 μm and a 14-bit A/D converter, already used for the high-resolution CT of other wooden materials [ 21 , 22 ]. The main characteristics of the X-ray source and the flat panel are summarized in Table 1 .…”

In this work, two historical flutes of the late eighteenth century were analysed by means of X-ray computed tomography (CT). The first one is a piccolo flute whose manufacturer is unknown, though some features could suggest an English or American origin. The second musical instrument is a baroque transverse flute, probably produced by Lorenzo Cerino, an Italian instrument maker active in Turin (Italy) in the late eighteenth century. Analyses carried out provided information on manufacturing techniques, materials and conservation state, and are suitable to plan restoration intervention. In particular, through the CT images, it was possible to observe the presence of defects, cracks, fractures and previous restorations, as well as indications of the tools used in the making of the instruments. Particular attention was directed towards extracting metrological information about the objects. In fact, this work is the first step of a study with a final aim of determining an operative protocol to enable the making of precise-sounding copies of ancient instruments starting from CT images, that can be used to plan a virtual restoration, consisting in the creation of digitally restored copies with a 3D printer.

“…The mechanism behind absorption Neutron Imaging is basically represented by a neutron beam which passes through an object and produces an image on a detector that depends on the number of absorbed neutrons [2], [3]. This way it becomes clear that the functioning is very similar to classical X-ray Imaging, a technique widely used in the diagnostics of Cultural Heritage [4]. Most of the time, Neutron Imaging and X-ray Imaging provide complementary information about the material under investigation.…”

The long-term purpose of this study is to assess the capabilities of the new Neutron Imaging beamline developed at the LENA facility of Pavia (Italy) for the characterisation of bronze artefacts. In this preliminary work, a set of Cu-based reference alloys has been produced and analysed in order to test and calibrate the facility. The first step involved the production of Cu-based alloys with chemical composition and microstructure similar to ancient artefacts. The chemical composition of the reference alloys was analysed by Optical Emission Spectroscopy. Secondly, some samples were artificially patinated with different chemical treatments obtaining an artificial corrosion products layer comparable to natural corrosion. X-Ray Diffraction, Scanning Electron Microscopy and Raman Spectroscopy have been used to characterise the corrosion patina. The main corrosion products on sulphate-induced patina are cuprite and brochantite, whereas atacamite and clinoatacamite were detected on chloride-induced patinas. Finally, preliminary Neutron Imaging measurements were performed on a first set of coated and uncoated specimens in order to try to correlate the neutrons attenuation coefficients with the chemical compositions with promising results.
