It is well known that the XRD technique can be applied for the mineralogical characterization of materials in the Cultural Heritage field.

Abstract
It is well known that the XRD technique can be applied for the mineralogical characterization of materials in the Cultural Heritage field. Generally the XRD technique is applied with non-transportable instruments, so limiting its field of application only to small dimension objects or requiring a destructive sampling in order to analyze artifacts which can not be transferred to the laboratories of analysis. In the last years many efforts have been dedicated to the development of portable systems, even if some limitation in terms of angular resolution or measurements time are often observed. In this work the upgrade of a commercial portable XRD system, previously installed at the LANDIS laboratory of the LNS-INFN of Catania (Italy) for in-situ applications in the Cultural Heritage field, is presented. The final version of the portable XRD system was used for the non-destructive mineralogical characterization of pigments. In particular its application, in combination with the portable PIXE technique developed at the LANDIS laboratory, for the quantitative characterization of Roman frescoes, is reported and discussed .I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
