Edge parameter operational space and trajectories for ITER

We propose a set of unified models to describe H-mode operation of the core plasma, the edge plasma including the transport barrier, and the scrape-off layer plasma to extrapolate to ITER. These models are being incorporated into several tokamak transport codes for use in extrapolating to ITER. Edge pedestal temperatures of 3.5-4 keV for edge densities between 6 and are predicted for ITER, which is the pedestal temperature range required for good confinement with ITG-based core models. The edge operational space predicted for ITER is compatible with both the required core density and core confinement and exhibits a large window between H-mode threshold and the ballooning limit.
