The 19th International Workshop on H-mode Physics and Transport Barriers (H-Mode Workshop 2024)

Display printing page


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. 

Meeting Format

The workshop will be organized around six broad topics of current interest. An overview talk, accompanied by discussion, will be presented for each topic. Each talk will be followed by a poster session of contributed papers, related to the topic. The International Advisory Committee solicits contributed papers that present and discuss recent experimental, theoretical or modeling studies of transport barriers, both internal and edge, as observed in numerous magnetic confinement machines and in a variety of magnetic topologies. All talks and posters will be presented in-person only.
