    Abstract

    To investigate material transport in scrape-off layer plasma and in/out asymmetries in divertor, 13CH4 was puffed at the end of 2002/2003 experimental campaign into ASDEX Upgrade from the outer mid-plane. Ex-situ analyses of the tiles were performed by secondary ion mass spectrometry and Rutherford backscattering spectrometry. The highest amount of 13C was detected at the top of inner divertor, and below the inner and outer strike points towards the roof baffle. The 13C peaks below the strike points correlate with thick long term deposition layers detected in ion beam analysis experiments.
