Divertor & High Heat Flux Components / Proceedings of the Nineteenth Topical Meeting on the Technology of Fusion Energy (TOFE) (Part 1)
The current T-tube divertor design consists of modular helium cooled units. The individual units consist of a steel inner cartridge enclosed in a tungsten alloy outer structure. On top of the outer tube is a layer of pure tungsten armor. Past design and analysis of the T-tube divertor concept has shown that it can accommodate a heat flux up to 10MW/m2. With recent concerns that steady state or transient heat fluxes may be higher than this in the divertor region, the T-tube concept was modified so that it may accommodate higher heat fluxes.
