What is it about?
Enabling hydrogen (H) mapping including local hydrogen concentration analyses at specific microstructural features is essential for understanding how H affects the properties of materials including embrittlement mechanisms and their synergies. In addition, spatial mapping and quantification of hydrogen isotopes is important to accurately predict the tritium inventory of future fusion power plants thus ensuring their safe and efficient operation.

Why is it important?
Atom probe tomography (APT) has the intrinsic capability to detect hydrogen and deuterium (D) and in principle the capacity for performing quantitative mapping of H within a material's microstructure. This work paved the way for establishing best practices in reporting APT data for the H analysis. We first summarize the key aspects of the intricacies of H analysis by APT and then propose a path for better reporting of the relevant data to support an interpretation of APT-based H analysis in materials.
