摘要: A loss button (80) for a traveling wave tube (10) has front and rear planar surfaces (92,94) of its ceramic pill-shaped button body (88) which are of coated metallic composition. The periphery is uncoated to permit r.f. energy to enter the button (80) through the cavity (82) of the planar, metallic, spacer (16) into which the button (80) is inserted. By coating the body surfaces (92,94), the button itself acts as a resonant cavity for attenuation of a predetermined bandwidth so that the dimensional changes that occur during heating to the surrounding and adjacent metallic elements, including the cavity (82) in the spacer (16) for receiving the button (80) and the adjacent braze washers, will not affect the attenuation band of the tube (10).

摘要: A method for bonding thermally-mismatched elements of a traveling wave tube (10) employs a metallic plate (68) of undulating character. The plate (68) is located at the region of the interface between tube elements formed of materials of materially-differing thermal character such as the ceramic termination piece (46) and an adjacent sever pole piece (54) of copper. Through either a brazing or a sintering process, pluralities of bonds are formed at points of tangency between the plate (68) and the two elements of differing thermal expansion coefficients. As a result, a good heat flow path, accompanied by a more stable r.f. interface, is formed between the materials that is not subject to fracture as are prior art diffusion bonds.
