MA-XRF measurement for corrosion assessment on bronze artefacts [PDF]

IMEKO TC-4 International Conference on Metrology for Archaeology and Cultural Heritage, 2019
In this study, an innovative portable macro X-Ray Fluorescence (MA-XRF) scanner prototype has been employed in order to gain information on composition and distribution of corrosion products artificially grown on Cu-based coupons. First results have shown the importance of using artificially corroded reference samples before any assessment on ...

Modular MA-XRF scanner potentialities and further advances

, 2020
In Heritage Science applications, in-situ and non-destructive analyses are commonly preferred. The valuable nature of historical objects often hinders the possibility of either sample or transport them into laboratories. Macro X-ray fluorescence (MA-XRF) has become widespread in the archaeometry field, due to its non-destructive and non-invasive ...

Visualising iron gall ink underdrawings in sixteenth century paintings in-situ by micro-XRF scanning (MA-XRF) and LED-excited IRR (LEDE-IRR)

Heritage Science, 2022
Until today, iron gall ink is classified as an exceptional underdrawing material for paintings. Its study and definite identification is usually based on invasive analysis.

Deep Learning Methods for Elemental Map Prediction from MA-XRF spectra

, 2023
Macro-XRF (MA-XRF) is a valuable non-destructive technique for investigating the chemical elemental composition of materials. MA-XRF data can be considered as high dimensional images, where a large vector of X-ray wavelengths emitted by excited atoms is computed for each pixel.
