Components for heat removal and particle exhaust
At present, the key problem of magnetic confinement fusion research seems to be to find physical and technical solutions for components which fulfil the combined requirements of heat removal and particle exhaust under long pulse conditions together with a self-consistent interaction with the plasma and its confinement requirements. Heat removal from the plasma and heat transfer between the hot plasma and the specific wall components are discussed. A few current concepts for a solution of the heat transfer problem are presented. Particle exhaust is discussed, with particular reference to ash removal in future reactors. Examples are given of several helium ash removal and helium exhaust techniques presently under investigation. Various technical examples are presented, including descriptions of the design features of ASDEX-Upgrade, the toroidal pump limiter ALT-II of TEXTOR and the actively cooled pump limiter of Tore Supra.
