Nondestructive pigment analysis in paint layers using ion-beam methodes on air

Restorers, art scientists and criminalogists are interested in the material composition of historic paintings. The substantial and structural analysis of details of paint layers are helpful and necessary to distinguish originals from forgeries, to decide on original states and later additives, to support statements on age and provenance and to understand aging phenomena. The basic idea of non-destructive paint layer analysis is demonstrated using PIXE at different proton energies.
