Migration of C-13 has been investigated at JET by puffing (CH4)-C-13 into the outer midplane at the end of the 2007 campaign. The C-13 deposition profile was measured with secondary ion mass spectrometry (SIMS) and Rutherford backscattering (RBS) techniques. C-13 was mainly found on Tile 1 and near the outer strike point (OSP) on Tile 7. The C-13 transport was modelled with the EDGE2D/NIMBUS code. Previous work indicates that migration pathways are: (1) through the main chamber scrape-off layer (SOL), (2) migration through the private flux region (PFR) aided by E x B drifts and (3) neutral migration originating near the strike points. The main contribution of this paper is to further describe the neutral migration.
