Prototype MA-XRD setup at the University of Antwerp. A) Photograph showing the micro-focus X-ray tube source (S), equipped with a double curved mirror M and detector for recording transmission XRD (D1) and XRF (D2) data: these components are positioned close to a painting mounted on a motorized stage; B) MA-XRD and C) MA-XRF images obtained by scanning a detail of the painting shown in D): scan size: 78×75 mm2, image step size: 0.5 mm in both directions, Dwell time: 2 s/pixel.
