Offering extreme sensitivity, high depth and lateral resolution together with high throughput, dynamic SIMS (Secondary Ion Mass Spectrometry) proves extremely useful for a wide range of nuclear science applications:

• Study of fission products behavior in irradiated nuclear fuels

• Characterization of plasma facing materials in fusion devices

• Investigation of long-term behavior of nuclear materials for safe waste disposal

• Uranium isotope analysis on safeguards environmental samples.

• Study of uranium accumulation processes in human tissues and cells.

The CAMECA IMS 7f-Auto is a versatile magnetic sector SIMS well suited for these applications. It offers depth profiling with excellent detection limits (ppb to ppm) and high depth resolution; elemental as well as isotopic information ranging from low mass (H) to high mass species (Pu and above); unique sub-μm resolution 2D and 3D imaging capabilities; as well as high throughput and automation. CAMECA also offers a Shielded IMS specifically developed for the analysis of highly radioactive samples.

In the example below, SIMS imaging measurements were performed on a cerium dioxide (CeO2) disk sample annealed at 1400°C for four hours after xenon implantation. CeO2 is usually considered as a non-radioactive surrogate of UO2 ceramics to simulate the properties of nuclear fuels during irradiation processes or long term storage.

Different applications covered by the CAMECA IMS 7f-Auto for materials analysis in nuclear science will be presented.
