Bifurcated neoclassical particle transport
The theory of neoclassical transport in an impure, toroidal plasma is extended to allow for steeper pressure and temperature gradients than are usually considered. It is found that the ion particle flux can be a non-monotonic function of these gradients for plasma parameters typical of the tokamak edge. A sudden transition between states of low and high confinement is therefore possible.
