Abstract

The interface of transport in toroidal plasmas is studied. The case, in which the gradient-flux relation is a multiplevalued function, is analyzed by use of the statistical theory of confined plasmas. An analytic formula for the determination of the interface of transport is given, taking an example of the transport in toroidal helical plasmas. The formula is given in a form of a dual Maxwell construction (rule of equal area). The location of the interface in stationary state and the access to the stationary state are discussed.
