Abstract

On the JFT-2M tokamak, the edge localized mode(ELM)induced by an external ergodic magnetic field is reproducibly obtained. After several single pulses, ELM behaves as bundles(3 or more bursts). Within one ELM, several separated bursts of magnetic fluctuations are observed. A statistical analysis shows that there are two kinds of coherent modes. One is a fixed low frequency mode which exists for all events and all shots. Another is a high frequency wide-spectrum mode which occurs only at the second magnetic burst. Some properties of the coherent modes are described.
