Abstract

We apply the computer simulation code, which was developed to study the flute mode fluctuations in the axisymmetric divertor, to the GAMMA10 tandem mirror in order to calculate the effects of the anisotropic electrostatic potential in the central cell. This initial anisotropic potential can be created by ECRH when it is turned on. It was found that the initial anisotropic potential profile caused the large energy radial transport by inducing flute-mode like fluctuations, which is not inconsistent with the GAMMA10 experimental results.
