| Research Abstract |
Visualization and quantification of the stochastic force in plasma turbulence have been investigated using fast camera imaging of plasma, Mach probes in the SOL and four HX arrays. The followings are achieved; 1) stochastic scaling law and gamma pdf of the SOL turbulence, 2) statistic law of magnetic pitch dependence of the coherent SOL turbulence, 3) development of the velocitometry for the SOL turbulence. Especially, the plasma flow measurements based on the Doppler shift spectroscopy for impurity ions, Mach probes for the SOL plasma, and velocitometry for fluctuations have been performed and it has been found that intrinsic rotation is triggered under the particular magnetic field configuration with strong positive curvature, and the rotation is the same as the plasma current. slab
