内容記述 |
A series of experiments using a newly constructed 130 MHz RF system has been conducted on the JIPP T-IIU tokamak since 1989. It is predicted theoretically that the fast wave in this range of frequency weakly interacts with particles . Though weak, two mechanisms of wave absorption were identified in the experiment : electron Landau/transit-time damping and 3rd ion cyclotron harmonic heating. The former has an intimate connection with fast wave current drive and the latter can provide a new regime of plasma heating or a possible method of controling transport of alpha-particles . It was found that the efficiency of the 3rd cyclotron heating is improved by using it in the combination with NBI and ICRF heating . The heating efficiency obtained is as high as that of conventional heating. The experimental results are also analyzed on the basis of a theory of the global wave which takes into account wave particle interactions . These mechanism of wave particle interactions are competing with each other as they will be under more realistic reactor conditions. |
