Research Abstract

An Electron Bernstein Wave (EBW) is attractive for heating of overdense plasmas. In the internal ring device Mini-RT an X-mode wave is injected into the plasma from the low-field-side, and the propagation of the wave inside the plasma is directly measured. Typical characteristics of the EBW such as a short wavelength, backward wave, a group velocity of the electron thermal velocity are experimentally identified. These results indicate the direct observation of the mode conversion from the X-mode to the EBW.
