For fusion reactors, which are expected to be inexhaustible energy sources, it is necessary to produce and confine high-temperature plasma exceeding 100 million degree Celsius. Understanding physics of the high-temperature plasma is essential for successful development of the fusion reactors. Especially, it is crucial to clarify how fuel, ash, and impurity particles behave in steady-state fusion plasma and how we can control them. Using “QUEST” spherical tokamak, we are investigating characteristics of the high-temperature plasma through development of advanced diagnostic systems, and developing control methods for steady-state fusion plasma.
