Outline of Final Research Achievements |
In high performance plasmas with the strong anisotropy, Alfven-ion-cyclotron (AIC) waves, are spontaneously excited. A microwave reflectometer system is introduced for the measurement of spatial structure of density fluctuations owing to the ICRF waves. Couplings between the ICRF waves for heating and the excited waves are clearly observed with the reflectometer for the first time. To evaluate wave-particle interactions, the behaviors of high-energy ions with energy more than 5 keV are detected with semiconductor detectors installed in the central and the east end cells. Ions escaped along the magnetic field line are detected in the east end. Fluctuations around 0.1 MHz which are difference frequencies between AIC waves are observed only on the signal of the detector installed in the east end. Pitch angle scattering of high-energy ions owing to those low-frequency waves are clearly indicated. Considerable energy transport to the ends owing to the AIC waves is suggested.
