The radiation and transport characteristics of ASDEX Upgrade discharges with a neon drive radiative mantle have been modelled using a 1-dimensional radial impurity transport code that has been coupled to a simple divertor model describing particle recycling and pumping. The code is well suited to describe the measured impurity line radiation, total, soft X-ray and bremsstrahlung radiation in regions of the plasma which are not dominated by 2-dimensional effects. The recycling and pumping behaviour of neon as well as the bulk transport of neon for radiative boundary scenarios are discussed.
Operational parameters of highly radiative divertor discharges in the ASDEX-Upgrade tokamak have also been investigated for different confinement modes and radiating species.
