Abstract

A modular He-cooled divertor concept is being developed at Forschungszentrum Karlsruhe. The design goal is to withstand a high heat flux of 10 MW/m² at least. The development covers the areas of design, analysis, materials, and manufacturing technology. In cooperation with the Efremov Institute, technological and manufacturing studies as well as thermohydraulic and gas flow dynamics experiments were performed for the current design
