| dc.description.abstract | The hypothesis is advanced and investigated that, in between or in the absence of ELMs (edge-localized-modes), the structure of the edge pedestal is determined by the transport requirements of plasma particle, momentum and energy balance and recycling neutral atoms. "Pedestal equations" following from this hypothesis are presented and applied to calculate the edge density, temperature, rotation velocity and radial electric field profiles in a DIII-D H (high)-mode plasma. A distinct pedestal structure in the density and temperature profiles and sharp negative peaks in the radial electric field and poloidal velocity just inside the separatrix are predicted, in qualitative and quantitative agreement with measured values. Details of the calculation are discussed. | en |
