Thermal annealing study of swift heavy-ion irradiated zirconia
Sintered samples of monoclinic zirconia (α-ZrO2) have been irradiated at room temperature with 6.0-GeV Pb ions in the electronic slowing down regime. X-ray diffraction (XRD) and micro-Raman spectroscopy measurements showed unambiguously that a transition to the ‘metastable’ tetragonal phase (β-ZrO2) occurred at a fluence of 6.5x10 cm for a large electronic stopping power value (≈ 32.5 MeV μm). ...
متن کاملStructural modification of swift heavy ion irradiated amorphous germanium layers
Swift heavy ion (SHI) irradiation of conventional glasses results in non-saturable plastic flow as a consequence of the ion hammering effect [1]. SHI irradiation of amorphous Si (a-Si) at non-perpendicular incidence also leads to unsaturated plastic flow, which shows a linear dependence on the ion fluence. The positive direction of flow suggests that a liquid phase with density similar to that ...

متن کاملEffect of swift heavy ion irradiations in polycrystalline aluminum nitride
Thanks to its high thermal conductivity, aluminum nitride may be a serious candidate as fuel coating for the Gas Fast Reactor. However, its behavior under irradiation is not entirely well understood. In order to catch a glimpse of this behavior, specimens were irradiated with swift heavy ions of different energies then characterised by both thermally stimulated luminescence and optical absorpti...
متن کاملPositron annihilation lifetime spectroscopy study of vacancy cluster evolution in swift heavy ion irradiated HOPG
Isotropic carbon is the material of choice for the rareisotope production target and beam catchers of the future Super-FRS. During operation both components are exposed to high-intensity ion beams and may suffer from radiation damage. To better understand damage formation processes in graphite, irradiation experiments were performed at the X0 beamline using 11.1 MeV/u Au-ions and different flue...
