A set of transport equations is analysed, including the bifurcation of theelectric field. The structure of the electric field is studied by use of thetheoretical model for the anomalous transport diffusivities.Multiple solutions of Er for the ambipolar condition are examined in the structure of the radial electric field. Parameter region in which the multiple solutions of electric field exist is studied by using the device parameter of compact helical system.A spatial structure of the radial electric field is also examined in the case using the device parameter of large helical device.
