SHIM 2015 Swift Heavy Ions in Matter

High density electronic excitation caused by fission fragments (FFs) in nuclear fuels and transmission targets is known to induce of ion tracks along the penetration path of FFs. Understanding of the structure of ion tracks together with the overlapping effects is one of the essentials for the development and assessment of the fuel/target materials under the extreme radiation condition. This...

Small angle X-ray scattering (SAXS) provides an interesting tool to study the structure of etched and un-etched ion tracks. It is non-destructive and can yield high precision measurements of the track radii in bulk amorphous and crystalline materials. Short acquisition times associated with the high photon flux at 3rd generation synchrotron devices facilitate in situ studies to determine the...

Defects in oxide materials created by irradiation are often revealed by optical absorption for the formation of colour centres and by transmission electron microscopy (TEM) for the individual latent track and microstructure evolution observations. The characterizations by X-Ray diffraction of irradiated materials were lesser used but are since few years under investigation going with the...

The localized nature of f-electrons results in systematic variation in the structures and electronic configurations accessible to oxides across the lanthanide and actinide series, with some exceptions due to partial f-electron itinerancy in the light actinides. To study the influence of the resulting variation in f-block oxide phase space on the response of these materials to highly-ionizing...

High energy proton microscopy (HEPM) or radiography is a novel technique for probing the interior of dense objects in static or dynamic experiments by mono-energetic beams of GeV-energy protons. A special system of magnetic lenses is employed for imaging and aberrations correction. Using this technique, one can measure the areal density distribution of a thick sample with sub-percent accuracy,...
