Description
The upgraded Ultra Clean Injector (UCI) of the Munich Accelerator Laboratory was used to measure T and D depth profiling with Accelerator Mass Spectrometry (AMS). The measurements were performed on carbon long term samples (LTS) placed between the vessel wall protection tiles of the ASDEX-Upgrade fusion experiment. The improvement of plasma confinement and stability after introducing the CDH-mode has been determined. The localization of a plasma disruption phenomenon was demonstrated. Complete toroidal and poloidal distribution of tritium depth profiles and inventory of tritium release in the tokamak were measured. Depth profiling of deuterium provided information about the quality of the neutral beam injection and efficiency of the fusion reaction in the tokamak. (authors)
