14th International Workshop on Hydrogen Isotopes in Fusion Reactor Materials
Meeting objective: This workshop is a satellite meeting of the 23rd International Conference on Plasma Surface Interactions in Controlled Fusion Devices (23rd-PSI) held on June 18 through 22, 2018 at Princeton University in Princeton, NJ, USA. It follows the tradition of the series of the last thirteen International Workshops on Hydrogen Isotopes in Fusion Reactor Materials (H-Workshop) that were organized as satellite workshops to PSI conferences. As its predecessors it is intended as a platform for experts in the field to present and discuss the latest scientific results. To fulfill its scope as a workshop ample time for discussion will be provided. The workshop will focus on experiments and modeling of hydrogen isotope interactions with fusion-reactor materials. Each speaker is given 25 minutes total (18 minutes presentation + 7 minutes discussion).

Presentations
The presentations will be done by oral in English (18 min. talk + 7 min. discussion). The Windows-operated computer is available for presentation. Mac users are requested to bring own computer and connection cable with him/her. Poster boards are available to display your poster used in the PSI conference and discuss during the H-Workshop. The participants who do not have presentations in the H-Workshop are also welcome to display her/his PSI conference posters. Note that there is no poster session in the H-Workshop program. You may display poster for all day and use coffee breaks and luch time etc. for discussion. If you would like to display your poster, please let us know by April 30. We need to know how many board we have to have.
