Material studies can reveal ancient objects' manufacturing processes and raw materials provenance. The expertise of artworks is driven by curators and heritage specialists. Some questions cannot be answered only by visual observation and literature knowledge and it is usual to call scientific laboratories, which developed analytical methodologies to probe objects. Data are extracted by preserving object integrity without taking samples and with no risk of damage to unique, fragile, and valuable pieces. For this purpose, we use protons, and alpha beams delivered by an accelerator. High energy particles induce X-ray emission (HE-PIXE) in the target and the study of the X-ray spectrum informs about the chemical elements present in the alloy [1]. To probe the material in-depth, we use
