Abstract. Ion Bernstein Wave (IBW) heating has been investigated in HT-7 superconducting tokamak. The electron heating mode was concentrated on a deuterium plasma with an injection power up to 320kW. Direct electron heating via electron Landau damping from the IBW was observed. The bulk electron temperature showed a significant rise with a heating factor, Te×ne/PRF, up to 7.4 ( eV×1013cm- 3/kW) and maximum increment of electron temperature was above 400 eV. IBW heating was combined with pellet injection, which also showed its unique merit.
