| Abstract Scope |
Hydrogen is famously difficult to measure spatially with confidence. Bulk quantification techniques measures general diffusion, but stops short of explaining specific kinetic behavior, especially at defects. Atom probe tomography (APT) and gallium focused ion beam induced time of flight secondary ion mass spectrometry (FIB tof-SIMS) are promising candidates to map hydrogen isotopes and provide information on hydrogen diffusion behavior due to the combination of spectrometry and spatial detection.
This talk will highlight the promises and challenges using APT and FIB tof-SIMS in hydrogen isotope detection. We will explore the measurement of hydrogen isotopes in irradiated structural steels and hydrogen in actinides. |
