Macro X-ray fluorescence analysis of XVI-XVII century Italian paintings and preliminary test for developing a combined fluorescence apparatus with digital radiography

Using portable instruments for the preservation of artworks in heritage science is more and common. Among techniques, Macro X-Ray Fluorescence (MA-XRF) digital radiography (DR) play a key-role field, therefore number MA-XRF scanners radiographic apparatuses have been developed this scope. Recently, INFN-CHNet group, network INFN devoted to cultural heritage, has scanner in-situ analyses. The instrument fully operative, it already employed museums, conservation centres out-door fields. In present paper, analysis conducted with on four Italian undertaking treatments at centre CCR “La Venaria Reale” are presented. Results preliminary test combine DR single apparatus also shown.
