[en] The design of actively cooled Plasma Facing Components for steady state operation faces a technological limitation in terms of extracted power per unit surface. In standard analysis of Scrape Off Layer (SOL) transport the power flux to the wall results from a balance between parallel and transverse transport. In approach, the energy deposition is governed by parallel transport while cross field transport determines the SOL radial depth, λ_q. As a consequence, large surface elements with shallow impinging angles have been designed to handle large powers at reasonable power flux. The actively cooled Inner First Wall (IFW) of Tore Supra follows this prescription. Infrared imaging (poloidal and toroidal coverage), Langmuir probes and thermocouples in a given poloidal plane are used in the experimental investigation of this corresponding specific geometry.
