Abstract

656,561. Travelling-wave tubes. STANDARD TELEPHONES & CABLES, Ltd. Feb. 20, 1948, No. 5011. Convention date, Feb. 26, 1947. [Class 39 (i)] In a travelling-wave amplifier, the electron beam is deflected periodically in passing through a cavity resonator 6, across an opening 9 in an electrode 8, so as to provide a bunched beam for transferring energy to a helix 11. A travelling wave having a component of velocity approximately equal to, and in the same direction as that of the bunched electrons, is set up in the helix. An accelerator electrode 10 is provided between the electrode 8 and the helix 11. The helix may be of decreasing pitch, or of constant pitch, but divided into sections having increasing potentials. The helix may be outside the envelope. A magnetic focussing coil is provided.
