| Outline of Final Research Achievements |
Improvement in engineering of tokamak reactors would be possible, if a hot plasma with the electron temperature up to a few keV and a hundred kilo amperes of plasma current could be non-inductively built up prior to inductive current drive up. From the view point of reactor engineering, electron cyclotron (EC) heating and current drive (ECH/ECCD) is attractive for the non-inductive build up. We have analyzed experimental results on small LATE device in addition to preliminary results on KSTAR and made some modeling to explore new ECH/ECCD method for generation of a hot plasma. We have found that usual O waves are useless and oblique X waves are appropriate for these startup plasmas.
