The patent describes a method and apparatus for efficiently removing heat from a traveling wave tube. A copper barrel heat sink casing is concentrically disposed about an inner glass or quartz tube with an annular space therebetween. Hollow ceramic spheres fill the space between the tube and the heat sink, and a small amount of fluid, such as a fluorocarbon serves as a vaporization agent to aid in the dissipation of the heat generated within the inner glass or quartz tube.
