Abstract
A new flux-gradient relation for the ion particle flux in the edge pedestal is derived from continuity and momentum balance, taking into account atomic physics, and cast in the form of a generalized ‘diffusion-pinch’ transport relation. This flux-gradient relation is used to derive a new expression for a first-principles calculation of the ion density gradient scale length.
