Abstract: 21st International Conference on Plasma-Surface Interactions in Controlled Fusion Devices (PSI), Natl Inst Fus Sci, Kanazawa, JAPAN, MAY 26-30, 2014; International audience; The WEST project, an on-going upgrade of Tore Supra, aims at providing the capability to test ITER relevant tungsten (W) divertor components under realistic tokamak plasma conditions. This work provides an assessment of tungsten sources in the edge plasma of WEST. The focus is on the contribution of the W coated pumping baffle. The modelling is performed with the Soledge2D-EIRENE transport code, which can include structures like the baffle explicitly in the computational grid. Gross erosion sources and prompt redeposition are then discussed in the light of recent new results. (C) 2014 Elsevier B.V. All rights reserved.
