Abstract
An improved confinement could be successfully achieved by an electrode biasing in the Heliotron J. The increases of ne and n eTe, the decrease of the potential fluctuation and the formation of strong negative Er were observed. The nonlinearity in the plasma resistance was found in the transition region and the clear hysteresis was observed. An intermittent transition phenomenon was found in the marginal-biasing condition. In the discharge, forward and backward transition repetitively occurred. This is considered due to the spontaneous change of the normalized poloidal torque around the transition threshold.
