Abstract

Migration of 13C has been investigated at JET by puffing 13CH4 into the outer midplane at the end of the 2007 campaign. The 13C deposition profile was measured with secondary ion mass spectrometry (SIMS) and Rutherford backscattering (RBS) techniques. 13C was mainly found on Tile 1 and near the outer strike point (OSP) on Tile 7. The 13C 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 × B drifts and (3) neutral migration originating near the strike points. The main contribution of this paper is to further describe the neutral migration.
