行波管。 In a conduction-cooled traveling wave tube, in which the heat generated in the collector is conductively radiated to the case substrate through an insulating cylinder and a heat radiator that are closely fitted to the outer periphery of the collector, the insulating cylinder and the heat radiator are tightly fitted and fixed to the collector. A conduction-cooled traveling wave tube characterized in that a cylindrical ring is passed through the screw used, and the coefficient of thermal expansion of the cylindrical ring is selected to be larger than the coefficient of thermal expansion of the screw.
