Abstract

1,067,464. Travelling wave tubes. MATSUSHITA ELECTRONICS CORPORATION. July 10, 1964 [July 12, 1963; Sept. 26, 1963; Nov. 1, 1963], No. 28662/64. Heading HID. An extremely high frequency travelling wave tube has a comb-type delay line k-a-b having lateral slots formed in the ridge of a ridge waveguide extending between an electron gun 12 at one end and a collector 11 at the other, wherein a ridge waveguide c-d provided at the electrongun end of the comb-type delay line has a ridge of lateral width the same as the comb and in continuation with the latter in a direction perpendicular to the electron beam axis, and wherein a longitudinal waveguide forms a continuation of the perpendicular ridge waveguide and extends towards the collector. The slots of the delay line are the same width as the teeth, and the electron beam passes through longitudinal slots formed in the ridge. The output longitudinal waveguide has a matching taper ridge section e-f, the energy being transmitted through a dielectric disc 33 which forms a seal for the electron tube. The slots are formed by a rotating cutting tool which may cut up to eight delay line simultaneously. The tube may operate as a backward wave oscillator, as shown, a thin film of resistive material 15 being provided on the surface of a port provided at the collector end of the delay line. Alternatively, the tube may operate as a forward wave amplifier. Specific dimensions of the waveguide and delay line are given.
