| Outline of Final Research Achievements |
For performance enhancement of self-burning fusion-plasmas, the fueling ratio ofions in DT nuclear fusion is essential. We proposed two methods for ion fueling ratio diagnostic by millimeter wave collective Thomson scattering; spectrum analysis and ion Bernstein wave detection.
In the first year, the frequency resolution is enhanced by a fast digitizer comibined with FFT analysis. In the second year, improvement of receiver antenna leads to succeed excited harmonic waves like an ion Bernstein wave.
