Migration and deposition of C-13 have been investigated at JET by injecting C-13-labelled methane at the outer divertor base at the end of the 2009 campaign. The C-13 deposition profile was measured with enhanced proton scattering (EPS) and secondary ion mass spectrometry (SIMS) techniques. A strong toroidal deposition band for C-13 was observed experimentally on each of the analysed four outer divertor floor tiles. In addition, C-13 was also found on the vertical edge of load bearing tile (LBT) and at the bottom of the LBT tile facing the puffing hole. Local C-13 migration in the vicinity of the injection location was modelled by the ERO code. The ERO simulations also produced the strong toroidal C-13 deposition band but there is strong deposition also on the vertical edge of the LBT tile and elsewhere on the horizontal part of the outer divertor floor tile.
