High–confinement radiative L–modes in ASDEX Upgrade
Abstract Experiments have been performed in the ASDEX Upgrade tokamak where plasmas are kept just below the H--mode threshold using feedback on the radiated power via seeded impurity. The resulting high--power L--modes show high confinement properties and no ELM activity due to the reduced pedestal height. The physics of these high--confinement L--modes is explored by means of integrated modeling to clarify the origin of the improved confinement.
