Ionenstrahlen zur Analyse von Wasserstoff in Festkörpern

Abstract

Summary Ion beams for analysis of hydrogen in solids Hydrogen is an important carrier of energy and, in the context of the growing request for renewable energy sources, a candidate for energy storage. Scientific questions relating to the study of the hydrogen of materials arise, on the one hand, from the interaction of hydrogen with the surrounding solid state material and, on the other hand, from the use of solids as a direct storage medium. Ion beam methods have proved suitable for this purpose. The methods secondary ion mass spectrometry (SIMS), elastic recoil detection analysis (ERD) and nuclear reaction analysis (NRA) are portrayed. Examples illustrate the techniques, applications for depth analysis are described and the sensitivity of the methods is given.
