Resonant inelastic X-ray scattering (RIXS) on actinide materialsStatus
GoalsWe will build and apply instrumentation for performing RIXS experiments on actinide containing material. RIXS can be used to provide detailed information on actinide electronic properties. It is a true bulk probe, an obvious advantage over surface sensitive XPS techniques. The RIXS instrumentation design will be based on an existing prototype from NIST (the United States National Institute of Standards). Expected resultsExpected impact on applied issues in the field of nuclear fission energy On the long term RIXS and related investigations will contribute substantially to a complete picture of bulk electronic properties of actinide systems. These results can be combined with refinements of theoretical quantum chemical models to describe magnetic and electronic properties of actinide elements with an unprecedented accuracy. Such fundamental understanding of f-electron properties can assist us in understanding various processes related to the nuclear fuel cycle such as the effectiveness of certain partitioning ligands, cation-cation multinuclear species formation in extraction of uranium and plutonium nuclides from irradiated fuel, or the phase segregation in fuels in high temperature GenIV reactors of the future. Expected impact on long term integration The instrumentation will be made available to other users at the INE-Beamline Pooled Facility. The instrumental design is modular and can therefore be also used in principle elsewhere. Reports |
