Abstract

Migration and deposition of ¹³C have been investigated at JET by injecting ¹³C-labelled methane at the outer divertor base at the end of the 2009 campaign. The ¹³C deposition profile was measured with enhanced proton scattering (EPS) and secondary ion mass spectrometry (SIMS) techniques. A strong toroidal deposition band for ¹³C was observed experimentally on each of the analysed four outer divertor floor tiles. In addition, ¹³C 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 ¹³C migration in the vicinity of the injection location was modelled by the ERO code. The ERO simulations also produced the strong toroidal ¹³C 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.
