抄録

The two-dimensional (2-D) image of high temperature plasmas in the GAMMA 10 tandem mirror has been measured at the central-cell by using a high-speed camera. Temporal behavior of visible image in the central-cell was observed with high-speed camera in the experiment of antenna optimization of central-ECRH system. Observed results showed a significant dependence on the position of the central-ECRH antenna. We discuss the characteristics of the fluctuation in the light emission intensity and the correlation with the radial distribution of electron density in the period of ECRH.
