Study of Radial Particle Flux due to Phase Difference Between Potential and Density Fluctuations

There is a radial particle transport as the loss induced by the fluctuations. It is possible to measure the potential and density fluctuations at the arbitrary point simultaneously by using gold neutral beam probe, and their phase difference between them. The radial particle transport induces the decreasing of the plasma stored energy. This phenomenon is estimated the theoretically-predicted loss process induced by the radial transport due to the phase difference between the potential and density fluctuations.
