The 51^st IEEE International Conference on Plasma Science (ICOPS) and the 4^th Asia-Pacific Conference on Plasma and Terahertz Science (APCOPTS) will take place on June 16-20, 2024, in Beijing International Convention Center, Beijing, China.

The 51^st IEEE International Conference on Plasma Science (ICOPS) will be held in Beijing, China, in 2024. ICOPS is an annual conference coordinated by the Plasma Science and Applications Committee (PSAC) of the IEEE Nuclear & Plasma Sciences Society (NPSS). 

The 1^st Asia-Pacific Conference on Plasma and Terahertz Science (APCOPTS) was organized in Xi'an, China as the future Asian version of ICOPS in 2018, which has a strong component on fast emerging terahertz science. The ICOPS 2024 is organized together with the 4^th APCOPTS. The program of the 51^st ICOPS & 4^th APCOPTS covers both traditional areas of plasma and terahertz science and new exploratory research areas. The conference offers an outstanding forum for scientists and engineers to learn further about some of the greatest advances in plasma science and technology, terahertz science and new exploratory research areas in recent years and to discuss future directions of research.
