In the way of the development of the current drive method which is the one of essential item for future fusion power plants, the study to get the current drive method with high-efficiency and high locality was executed. Main results are shown as the followings1) On high toroidal field superconducting tokamak, TRIAM-1M, fundamental X-mode electron cyclotron current drive (ECCD) experiments were carried out by use of 170GHz high power microwave system. As the results, fundamental X-mode ECCD has high efficiency and high locality.2) The absorption power of microwave was calculated by TASK/WR code and its value was used to estimate the current drive efficiency.3)The remote steering antenna, which is useful in ITER, was developed and its performance was made sure in TRIAM-1M high power experiments.4)Identical view hard X-ray measurement system to estimate current profile in LHCD plasma was developed and the current profile was measured in an LHCD plasma.5)Electron Bernstain wave (EBW) current drive experiments were executed on CPD and plasma current of 3kA was able to start-up by use of 8.2GHz microwave system without the assist of ohmic heating.6)The antenna, which has the capability of control of injection angle and polarization of microwave, was developed and its good performance was demonstrated successfully.
