| Outline of Final Research Achievements |
We developed the diagnostics system for measuring the gradient and curvature of the electron temperature and the electron density profiles in high-temperature plasma. Because the gradient and curvature of the plasma are considered to affect the plasma confinement, this measurement is important for the the study of fusion plasma science. We performed the diagnostics in the large helical device (LHD) plasma and have successfully obtained the temporal behavior of these parameter. Comparing with the conventional diagnostics, the characteristics of this technique has been clarified.
