Abstract
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 is a no
nmonotonic function of these gradients for plasma parameters typical o
f the tokamak edge. A sudden transition between states of low and high
confinement is therefore possible. [S1070-664X(98)03411-9].
