Research Abstract
The Electron Bernstein Wave (EBW) is one of the main heating/current drive methods for the QUEST spherical tokamak of the Kyushu University. Electron Cyclotron Resonance Heating (ECRH) is the most promising heating/current drive method of the fusion plasmas. One important drawback is the electron cyclotron wave cannot propagate inside over-dense plasma. This density limit is critical in the high beta plasma such as spherical tokamak. The EBW can only be excited in the plasma via mode conversion process from electro-magnetic wave injected from outside of the plasma. Due to this indirect excitation process of the wave the direct detection of the EBW inside the plasma and the study of its behavior is required and necessary to optimize the EBW heating. This project is to detect the EBW inside the plasma directly by the electromagnetic wave scattering using sub-Tera Hz wave. Method to design sub-Tera Hz scattering system and estimate EBW quasi-optical wave propagation are developed.
