| Research Abstract |
The Electron Bernstein Wave (EBW) is quite attractive for plasma heating and current drive in a fusion reactor, because the EBW can propagate even in so-called overdense plasmas. There are three methods to excite the EBW in a torus plasma; (i) X-mode wave injection from the low field side, (ii) oblique O-mode wave injection from the low field side and (iii) X-mode wave injection from the high field side. In this research we have succeeded to excite the EBW in an internal ring device Mini-RT for these three methods, and we have found the characteristics of the EBW such as the short wavelength and backward wave with the direct measurement of the EBW in the plasma by inserting receive antennae into the torus plasma.
