Description
Existence of the edge transport barrier produces instabilities due to a steep pressure gradient and a surface current. Behaviors of the different types of edge localized modes (ELMs) are reviewed based on experimental observations in many tokamak devices, and the effects of ELMs on energy confinement, global stability, and divertor heat load are included. Controls of these instabilities are essential for optimization of the integrated tokamak performance. (author)
