| 摘要 |
A delay line for travelling-wave tubes, comprising a hollow guide with successive transversely disposed discs having elongated attenuation members which project into the interior of the hollow wave guide, with the longitudinal axes of such attenuation members extending at least approximately parallel to the longitudinal axis of the delay line and mechanically firmly supported in recesses in the transverse discs. The attenuation members are retained by a press or force fit with the transverse discs, and may be provided in the portion thereof surrounded by the associated transverse disc with at least one notch which extends transversely to the longitudinal axes of the members and which is at least partially filled with the ductile material of such associated transverse disc.
