Journal Article on Ion Milling for Cross-Section Samples

Together with colleagues from Hitachi High-Technologies Europe, Margaret Smith and Karen Thompson recently published an article in Heritage Science on the application of ion milling to the preparation and analysis of cross-section samples.

Set of four images to illustrate the use of of ion milling for cross-section samples of painted textile. The images are arranged to show clockwise from top left, An except of a painted textile banner with sample location; Sample under light microscopy dark field ×50 magnification that shows the different layers of textile and paint; SEM-EDX analysis of sample cross-section showing the presence of lead indicated in yellow; Sample cross-section ion-milled ×1000 magnification

Accurate materials analysis plays an important role in the study and conservation of historical objects. This research investigates how the level of detail that can be seen in the heterogeneous layers of cross-sections where a textile is present is greatly improved by the ion-milling of the samples.
