Its ability to resolve isotopes is especially attractive in studying transmutation products of single crystal tungsten (SCW) post neutron irradiation. Tungsten (W) is a contender of plasma facing materials (PFMs) due to its high thermal and radiological stability. PFMs to be used in the construction of fusion vessels are subject to high temperature and neutron irradiation, resulting in changes to materials including transmutation, which ultimately impact material mechanical and thermal properties. We used IONTOF TOF.SIMS V instrument equipped with a 30 keV Bi₃⁺ primary ion beam to study pristine SCW and irradiated SCW speciemens. Scanning electron microscope coupled with focused ion beam (SEM-FIB) was used to reduce the dosage of neutron irradiated tungsten and prepare for specimens for SIMS analysis. Static ToF-SIMS spectra were obtained, and transmutation product peak identification was presented in this work. Identified molecules and molecular fragments were compared against isotope theoretical mass to charge ratios of tungsten, rhenium, osmium, and other relevant products. Our results show that ToF-SIMS provides a viable means to study transmutation products of W post neutron irradiation.

Due to their technical and compositional complexity, a multi-analytical approach was adopted, combining non-invasive and micro-destructive investigations. Non-invasive investigations, including Digital Optical Microscope (DOM), UV-Induced Visible Fluorescence (UVF), and infrared reflectography (IRR), provided valuable information on the decorative surface and preliminary data on deterioration. In addition, portable X-ray fluorescence (p-XRF) and Fibre-Optic Reflectance Spectroscopy (FORS) analyses were used to identify chromophores in the painted, silvered, and gold-plated layers. Further insights into the execution technique were gained through micro-destructive investigations on sampled materials, employing optical microscopy (OM) on polished and stratigraphic sections, along with Scanning Electron Microscopy (SEM) coupled with Energy Dispersive X-ray spectrometry (EDX). Finally, biological studies were carried out to characterize the leather support, integrated with entomological and microbiological analyses to identify any degradation phenomena due to biological activity. The results indicate that the three altar frontals faithfully reflect the typical characteristics of this artwork type. They also exhibit common degradation forms, such as the darkening of silver leaf, indicating their age and conditions over time.
