The importance of retaining the azimuthal variation of the electrostatic potential in transport and ambipolarity studies is demonstrated. Because the azimuthal electric field must satisfy quasi-neutrality, equilibrium ambipolar operation permitting different ambipolar roots at different radii is energetically not possible. Moreover, in the tandem mirror model considered herein, the only acceptable ambipolar root is not accessible for significantly inverted source profiles and does not permit the density profile to invert radially.
