Abstract

Density fluctuations in NBI (neutral beam injection) plasmas in Heliotron E were studied using the laser phase contrast (LPC) method. A counter-propagating pair of waves, electron mode and ion mode, was observed in the edge region. Their dependences on the ion and electron temperatures are discussed in an experiment where ECH (electron cyclotron heating) pulses were superposed on the NBI plasmas.
