A furnace and environmental cell for the in situ investigation of molten salt electrolysis using high-energy X-ray diffraction

M. J. Styles, M. R. Rowles, I. C. Madsen, K. McGregor, A. J. Urban, G. A. Snook, N. V. Y. Scarlett and D. P. Riley

Synopsis: This paper describes the design and construction of a new molten salt cell and furnace, which together allow individual cell components such as anodes and cathodes to be studied in situ using synchrotron-based energy-dispersive X-ray diffraction. The performance of this equipment is demonstrated by an in situ study of a model inert anode within an operational Fray-Farthing-Chen Cambridge titanium electrowinning cell, using the JEEP beamline at the Diamond Light Source.

Increase of lifespan for glioma-bearing rats by using minibeam radiation therapy

Y. Prezado, S. Sarun, S. Gil, P. Deman, A. Bouchet and G. Le Duc

Synopsis: A new radiotherapy technique, minibeam radiation therapy, combining submillimetric field sizes and a spatial fractionation of the dose is under development at the biomedical beamline of the ESRF. Here the therapeutic effectiveness of single-fraction minibeam radiation therapy on 9L gliosarcoma-bearing rats is assessed.

X-ray photon correlation spectroscopy in systems without long-range order: existence of an intermediate-field regime

K. Ludwig

Synopsis: In coherent scattering from a material with only short-range order, it is shown that there exists an `intermediate-field' regime in which the ensemble averages of the scattered intensity and of the structure factor are equal. In addition, the ensemble-averaged temporal correlations of the intensity and of the structure factor are equal.

Global and local hard X-ray tomography of a centimeter-size tumor vessel tree

S. Lang, M. Dominietto, P. Cattin, A. Ulmann-Schuler, T. Weitkamp and B. Müller

Synopsis: Local tomography data from a set of multiscale measurements on a tumor vessel tree were quantitatively compared with global data, and algorithms were used to match the reconstructed absorption coefficients. The study shows that the systematic differences in the absorption coefficients between the local and the global data arise not only from the truncated projections but to a greater extent from the optical components of the detector used.
