The design and performance characteristics of new compact and light-weight X-ray detectors designed for the Diamond powder diffraction beamline I11 are presented.

Cost-effective upgrade of a focusing system for inelastic X-ray scattering experiments under high pressure

This paper describes a scheme utilizing a set of low-cost and compact Kirkpatrick–Baez mirrors for upgrading the optical system of the Taiwan Inelastic X-ray Scattering beamline at SPring-8 for high-pressure experiments using diamond-anvil cells. The scheme as implemented improves the focus to 13 µm × 16 µm with transmission of up to 72%.

Relics in medieval altarpieces? Combining X-ray tomographic, laminographic and phase-contrast imaging to visualize thin organic objects in paintings

X-ray radiography is a common tool for the study of old master paintings. This paper presents synchroton-based imaging techniques that enable three-dimensional imaging of paint layers and their substructure.

Dose, exposure time and resolution in serial X-ray crystallography

Using detailed simulation and analytical models, the exposure time is estimated for serial crystallography, where hydrated laser-aligned proteins are sprayed across a continuous synchrotron beam.

Radiobiological features of the anti-cancer strategies involving synchrotron X-rays

Principles, radiobiological mechanisms and results of different anti-glioma applications of synchrotron radiation are reviewed and compared.

Microstrain in hydroxyapatite carbon nanotube composites

Synchrotron radiation diffraction data were collected from hydroxyapatite–carbon nanotube bioceramic composites to determine the crystallite size and to measure changes in non-uniform strain. Increasing the amount of carbon nanotubes in the composite has increased the strain in the material, which is undesirable for biomedical implant applications.
