Abstract
A simple model for tandem mirror transport and ambipolarity is formulated by neglecting temperature gradients. It is shown that the shape of the radial fueling profile in the center cell and the retention of induced azimuthal electric fields are important in determining the self‐consistent radial potential drop ΔΦ and the resulting neoclassical confinement time τ⊥. Numerical solution of the transport equations yields the approximate scaling law τ⊥∝(ΔΦ)−2 when eΔΦ>T and T is held fixed.Keywords
