Abstract

A heat flux deposition code is a very useful tool for the design of plasma-facing components. The classical cosine model representative of the convective parallel heat flux was coded within the standard finite element code of the CEA Castem 2000. Two perturbations to the idealized magnetic surfaces wer taken into account: the Shafranov shift and the ripple of the toroidal magnetic field. The calculation scheme - named Tokaflu - was confronted to previous computations on bottom modular limiters and to experiments on the inner first wall. The code was used to optimise the shape of future plasma-facing components in Tore Supra designed for the CIEL project, namely the toroidal pumped limiter and its neutralizers. Developments are under way to include the shadowing of the components, other power deposition and its neutralizers. Developments are under way to include the shadowing of the components, other power deposition schemes and possibly later plasma sections other than circular.
