Analysis of hydrogen and deuterium by secondary ion mass spectrometry as applied to fusion technology

This paper will focus on hydrogen detection using secondary ion mass spectrometry (SIMS), an established technique that has been used relatively infrequently for hydrogen analysis in fusion research. Fusion technology‐related examples will be shown of hydrogen detection using SIMS. These include flux and energy measurements of H and D in the edge plasma, H and D isotope saturation and exchange studies; and species‐mix determination for H and D in neutral beams from high power injectors.
