The 19th International Workshop on H-mode Physics and Transport Barriers will be held from September 24-27, 2024. The purpose of this biennial workshop is to present and discuss the status of H-mode and internal transport barrier experiments, theory and modeling in magnetic fusion research and to discuss scientific solutions of H-mode control for the purpose of exploring possibilities of advanced operating scenarios in next step fusion devices. The workshop is hosted by QST-Naka.
