| Research Abstract |
Active and passive control methods of Edge Localized Modes (ELMs) at the edge transport barrier have been investigated through comparative experiments using some devices. In the research of small ELMs as a passive control, conditions to obtain small ELMs have been compared. Then, it is revealed that the different type of small ELMs can be obtained depending on the value of the edge collisionality. As for an active control, it is confirmed that the localized injection of the electron cyclotron wave or the lower-hybrid wave to the edge plasma region can increase the ELM frequency.
