    To investigate material transport in scrape-off layer plasma and long term deposition in divertor, 13CH4 was puffed at the end of 2004 and 2005 experimental campaigns into ASDEX Upgrade from the outer mid-plane.
    Ex situ analyses of the tiles were performed by secondary ion mass spectrometry.
    The peaks of 13C were detected below the bottom inner strike point and at the horizontal tile at the outer lower divertor. It was detected ∼21% of the total puffed 13C amount.
    The deposition rate for carbon by plasma was also calculated in long term experiment. It was obtained to be 22 × 10−3 and 8.7 × 10−3 g/s for the upper (campaign 2004) and lower (campaign 2003) divertors, respectively.
