Abstract

Stability against the interchange mode in heliotron devices is investigated, taking into account the effects of the resistivity, current diffusivity, ion viscosity, and thermal diffusivity. Critical beta for the low-mode-number stability is found at the finite beta value. For the range of plasma parameters of the present experiments, the resistive mode and current diffusive mode set comparable critical beta values, which are consistent with experimental observations. In future high-temperature plasmas, the current-diffusive mode could be important in determining the stability limit for the global mode.
