The study of ambipolar electrostatic confinement of central cell ions requires equilibrium models in which the electrostatic forces are treated on an equal footing with the magnetostatic ones. The three‐dimensional guiding center fluid equilibrium model has been generalized to include these ambipolar effects; quasineutrality is used to obtain the potential &fgr;. There is no restriction to low‐beta or long‐thin approximations. In this multiregion, multicomponent model omnigenity is required for each species seprately; this is the less stringent requirement of multigenity.
