Elemental mapping of Portuguese ceramic pieces with a full-field XRF scanner based on a 2D-THCOBRA detector

In this work, we present a novel application of the full-field energy-dispersive X-ray fluorescence (EDXRF) imaging system based on MicroPattern Gaseous Detector (2D-THCOBRA) in cultural heritage field. The detector has an intrinsic capability with spatial resolution $$400\,{\upmu }\mathrm { m}\ \mathrm {FWHM}$$ , and is energy sensitive, presenting approximately $$1\ {keV\ FWHM}$$ at $$5.9\ {keV}$$ . XRF scanner 2D-THCOBRA allows mapping distribution elements large area samples high detection efficiency ( $$75\%$$ ), being very promising choice for elemental analysis samples. have demonstrated capabilities used it to assess restoration Portuguese faience piece.
