| Research Abstract |
A new mirror which enabled high-field side injection of electron cyclotron waves for mode conversion to electron Bernstein waves was installed in the vacuum vessel of large helical device LHD of national institute of fusion science. In the high-density plasma heating experiment where the electron density around the plasma center was higher than the cut-off density of applied waves, an increase in the electron temperature at the plasma center was realized. The electron density at the plasma center was 1.6 times higher than the left-hand cut-off density of the applied 77GHz wave, then the increase in the electron temperature at the plasma center should be attributed to the electron Bernstein wave which was mode-converted from the injected electron cyclotron wave.
