“…More details on the used microprobe end-station including the in-vacuum and the external beam setup can be found elsewhere. [15,16,18] The referred experimental chamber upgrade was performed in order to allow in situ electrical characterization as well as ionoluminescence (IL) measurements simultaneously with conventional IBA techniques as PIXE and RBS. Figure 1 shows a schematic of the chamber with the distribution of the different detectors associated with the different characterization techniques.…”

In situ characterization of β‐Ga2O3 flakes during proton irradiation is performed using ionoluminescence and electrical measurements. The quenching of the native blue‐UV emission bands due to irradiation‐induced defects in real time is monitored by ionoluminescence. Measurements of the I–V characteristics during irradiation present a good response of Ga2O3 for particle detection and a good radiation resistance.

“…Smalt is a glassy pigment that develops color with cobalt element. It has been industrialized in Europe since the 15th century and it has been widely used in European oil paintings and church murals [22][23][24][25][26][27]. In the 19th century, it was gradually replaced by other inexpensive arti cial blue pigments.…”

Murals of Cave 256, Mogao Grottoes consist of several layers, with the outermost layer overlays all others. The bottom layer was painted in the Five Dynasties. The outermost layer was mural of the Song Dynasty. Statues were repainted in the Qing Dynasty. We found that different blue pigments are used through research of murals and statues of different dynasties in Cave 256. In order to know the type of blue pigments, technology such as X-ray diffraction, microscopic FTIR spectroscopy and polarizing microscope were used for analysis of trace samples based on non-destructive research through the portable X-ray fluorescence. As a result, we know that Lazurite was used as blue pigment in murals of the Five Dynasties and Azurite was used in the Song Dynasty. Smalt used in statues of the Qing Dynasty was first discovered in Mogao Grottoes. Difference in blue pigments reflects the social development at that time to a certain extent. It can be inferred from the discovery of smalt that statues of the Qing Dynasty in Cave 256 were repainted in the first half of the 19th century.

“…Working with an external beam set-up, especially for cultural heritage studies, as in many ion beam laboratories [6][7][8][9][10][11][12][13][14][15][16][17], has the advantage of allowing fast and efficient measurements with direct analysis and easy positioning of object having any size and shape, without need of sampling, and no charging effects and heating from beam irradiation, thus strongly reducing the risk of damaging the object (truly "not deliberately destructive" measurements).…”

External Beam IBA Measurements for Cultural Heritage

Ion beam analysis (IBA) methods refer to a set of analytical techniques based on the interactions of energetic ions, produced by a particle accelerator, with matter. The result of such interactions is the emission of characteristic radiation, X and gamma rays, and charged particles, which, upon detection, provide valuable information on the absolute concentration and depth distribution of the elements in the bombarded material. Moreover, IBA techniques can be performed while maintaining the object to be investigated at atmospheric pressure, without placing it in vacuum, in an analysis chamber, with the impinging ion beam extracted from the in-vacuum beamline of the accelerator, avoiding the need of invasive sampling and greatly easing the object positioning, thus allowing precious and big or large artefacts to be studied. This feature has opened the way for applications of IBA techniques for compositional analysis in cultural heritage studies, providing detailed and complete information about elemental compositions and depth distributions of analysed materials that are otherwise difficult or impossible for other analytical techniques. In this paper, the basic principles of the main IBA techniques applied to cultural heritage, namely, particle induced X-ray emission (PIXE), particle induced Gamma-ray emission (PIGE), and Rutherford or elastic backscattering spectrometry (RBS/EBS), will be recalled, and specific and practical details on how these techniques can be used for analysing cultural heritage objects with external beam set-ups will be provided.
