Edge Turbulence/Fluctuation Observation at "High Density Mode" in GAMMA 10 by Fast Camera

Edge plasma behavior was observed by fast camera at high density central-cell plasma in GAMMA 10. The plasma performance was better when the plasma rotated clockwise to the magnetic field. Also, when the interaction with the central-cell limiter was observed, the plasma stored energy was deteriorated. These results were very similar that of high potential central-cell plasma experiment as previously reported. Several rotation mechanisms exist, and on the empirical basis it is suggested the interaction with the central-cell limiter is important.
