Properties Required for Isotropic Graphite As First Wall Component of Fusion Device

摘要: An isotropic graphite has been widely used for the first wall components of fusion devices as a high heat flux and stable material to plasmas. Since atomic number carbon is low, radiation loss from plasma can be largely suppressed compared with metal impurities such iron.It known that primary limiter armor tiles Doublet III TFTR were made POCO those plasmas.It required low rates outgassing, recycling sputtering, sublimation temperature higher mechanical strength.This report describes methods satisfy these requirements, examines fluxes tiles.
