Confinement and transport studies of conventional scenarios in ASDEX Upgeade

摘要

Confinement studies of conventional scenarios, i.e. L and H modes, in ASDEX Upgrade indicate that the ion and electron temperature profiles are generally limited by a critical value of ΔT/T. When this is the case the profiles are stiff: core temperatures are proportional to pedestal Temperatures. Transport simulations based on turbulence driven by an ion temperature gradient show Good agreement with the ion experimental data for H modes.
