Evident increases in plasma stored energy have been observed in the Compact Helical System (CHS) by injecting nearly X-mode-polarized 54.5 GHz electron cyclotron (EC) waves from the high-field side. An additional plane mirror that enabled the high-field side injection of the EC waves was installed. The centrally peaked and increased electron temperature distributions with the X-mode wave directions which are not aimed at the fundamental resonance layer at the plasma core region strongly suggest that the heating effects occurred due to the excitation of the electron Bernstein waves via mode conversion from the X-mode waves injected from the high-field side.
