Swift heavy ion irradiation of SrTiO3 under grazing incidence
The irradiation of SrTiO3 single crystals with swift heavy ions leads to modifications of the surface. The details of the morphology of these modifications depends strongly on the angle of incidence and can be characterized by atomic force microscopy. At glancing angles, discontinuous chains of nanosized hillocks appear on the surface. The latent track radius can be determined from the variatio...
متن کاملLow fluence swift heavy ion irradiation of amorphous germanium
Synchrotron based Small Angle X-ray Scattering (SAXS) give evidence of SHI irradiation induced ion-tracks in a-Ge. The scattering spectra of the ion-tracks can be fitted by using a model function of a cylindrical electron density distribution with an internal core shell structure. Core and shell are both of constant electron density but one being overthe other under-dense with respect to the su...
متن کاملDegradation of cured polyepoxy under swift heavy ion irradiation
Glass fibre reinforced plastic (GFRP) is considered as structure support and insulating material for the new superconducting FAIR magnets. GFRP (G11) is a composite material consisting of woven glass fibres (volume fraction ~50 %) and cured polymer resin (e.g. amine-cured epoxy). The material will be exposed to cryogenic temperatures, high radiation levels and dynamic mechanical loads (Lorentzi...
متن کاملDislocation loop formation by swift heavy ion irradiation of metals.
A coupled two-temperature, molecular dynamics methodology is used to simulate the structural evolution of bcc metals (Fe and W) and fcc metals (Cu and Ni) following irradiation by swift heavy ions. Electronic temperature dependent electronic specific heat capacities and electron-phonon coupling strengths are used to capture the full effects of the variation in the electronic density of states. ...
متن کاملMechanical degradation of polyimide induced by swift heavy ion irradiation
In the new superconducting FAIR magnets, polyimide films (Kapton) will be used as insulator. During operation, the material is exposed to high-dose radiation and it has to withstand enormous mechanical forces induced by the magnet field ramping. For better lifetime estimation, this study investigates radiation-induced degradation of the mechanical properties of Kapton by tensile strength measur...
