Proton beam irradiation induces invisible modifications under the surface of painted parchment

A maximum radiation dose of 0.5 µC/cm 2 can be considered as ‘safe boundary’ for 2.3 MeV PIXE analysis of parchment under the applied conditions and the presence of ultramarine paint on the parchment surface appears to increase the harmful effects of proton radiation.

In Situ Modification and Analysis of the Composition and Crystal Structure of a Silicon Target by Ion-Beam Methods

The method of Rutherford backscattering (RBS) with channeling is widely used in compositional analysis and structural determination. An experimental process line for in situ ion implantation and RBS

Informative Potential of Multiscale Observations in Archaeological Biominerals Down to Nanoscale

Humans have intentionally used biological materials such as bone, ivory and shells since prehistoric times due to their particular physical and chemical properties. The composite nature of biological

Utilisation combinée des rayons X et gamma émis lors de l'interaction avec la matière d'ions légers aux énergies intermédiaires : des mécanismes primaires de réaction aux applications

PIXE (Particle Induced X-ray Emission) et PIGE (Particle Induced Gamma-ray Emission) sont des methodes d’analyse par faisceau d’ions, multielementaires et non destructives. Elles sont basees sur la

Protocol for the Examination of the Ancient Ivories from Arslan Tash: A Palaeo-Technological Approach

The first studies on ancient Near Eastern ivories centred on iconography and style, an approach that became standard. Technological features have only come into focus in recent years in studies by



Discovering vanished paints and naturally formed gold nanoparticles on 2800 years old phoenician ivories using SR-FF-microXRF with the color X-ray camera.

Phoenician ivory objects from the collections of the Badisches Landesmuseum, Karlsruhe, Germany, have been studied with full field X-ray fluorescence microimaging to noninvasively study trace metal distributions at the surface of the archeological ivory objects.

Photon-based techniques for nondestructive subsurface analysis of painted cultural heritage artifacts.

A number of fundamentally new approaches for fully imaging the buildup of hidden paint layers and other complex three-dimensional (3D) substructures have been put into practice, and these developments and their recent practical application with CH artifacts are discussed.

Revealing hidden paint layers in oil paintings by means of scanning macro-XRF: a mock-up study based on Rembrandt's “An old man in military costume”

Over the past several decades the oeuvre of Rembrandt has been the subject of extensive art historical and scientific investigations. One of the most striking features to emerge is his frequent

Development of a nondestructive method for underglaze painted tiles—demonstrated by the analysis of Persian objects from the nineteenth century

An analytical method developed for the nondestructive study of nineteenth-century Persian polychrome underglaze painted tiles established the presence of Cr- and U-based colorants as new materials in nineteenth- century Persian tilemaking.

Microscale imaging of the preservation state of 5,000-year-old archaeological bones by synchrotron infrared microspectroscopy

Th thin sections of about 5,000-year-old archaeological bones have been analysed in transmission mode at the IRIS beamline to determine markers of the state of bone preservation at the microscale and this data allow us to precisely evaluate the state-of- preservation of a 5, thousands of year-old bone at the histological level.
