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.
