Summary

All papers were peer-reviewed. Hydrogen plays a key role in materials, beneficial in some cases, problematic in others. In all such systems a detailed understanding of the hydrogen-based interaction is necessary for control, improvements, and for possible new applications. This hydrogen workshop proceeding incorporates contributions from semi-conducting, normal conducting (metals) and superconducting materials, as well as vacuum communities who deal with the hydrogen-materials issue. The technical areas covered in these proceedings include hydrogen in materials, hydrogen interactions and dynamics in semiconductors, hydrogen adsorption-storage-generation and distribution, hydrogen in niobium, hydrogen in vacuum systems, gaseous hydrogen accelerator structures, and magnetically suspended liquid hydrogen transfer lines.
