Heavy-ion beam induced effects in enriched gadolinium target films prepared by molecular plating
2017, Nuclear Instruments and Methods in Physics Research, Section B: Beam Interactions with Materials and AtomsCitation Excerpt :Although many publications exist on the topic from the material science perspective (see for example [10,11] and references therein) and these offer important insights, one aspect of nuclear targetry often unexplored pertains to irradiation effects. Articles focusing on the characterization of nuclear targets document non-trivial physical and chemical transformations after heavy-ion beam irradiation [12,13], which can non-negligibly affect the relevant experiments. These studies are of particular interest for experiments where targets must withstand high beam intensities and doses, such as in the production of known transactinides and synthesis of new superheavy elements [14,15].
Changes in surface composition and morphology of UF<inf>4</inf> targets during heavy ion irradiation
2004, Nuclear Instruments and Methods in Physics Research, Section B: Beam Interactions with Materials and AtomsCitation Excerpt :Unlike the similar swelling seen in oxides, such as SiO2 where there is a straightforward interpretation in terms of a density change due to amorphization [17], the origin of the swelling in LiF, where amorphization is thought to be less likely, is said to be more likely to arise from the formation of specific defects or defect clusters [18]. Our observations do echo those of Stiebing et al. [4], who found massive microstructural changes in UF4 targets sandwiched between C foils that had been exposed to a variety of heavy-ion beams. In some cases UF4 appeared to have migrated from some areas and piled up on others.
