| Outline of Final Research Achievements |
Further improvement of plasma confinement is one of the issues for the fusion reactor. For this reason, development of electron density profile measurement device is important. We have developed the millimeter-wave interferometer with several hundred of measurement channel by employing a leaky-wave antenna. We simulative applied this system to a dielectric rod in the lab to evaluate system spatial resolution. In the measurement results, measured and actual rod positions are in good agreement, however, measured profile is blurred. We have employed the genetic algorithm (GA) to sharpen the profile. We confirmed that estimated profile by the GA is good agreement with the actual rod-shape.
