Evaluation of the Axisymmetricity of the Central-Cell Plasma Using a Segmented Limiter on GAMMA 10

Non-axisymmetry of the plasmas as well as fluctuations including turbulence causes the radial transport in a mirror configuration. The azimuthal distribution and fluctuations of floating potentials on a segmented limiter in the central cell are measured to evaluate the degree of the axisymmetry of plasmas.
