A LOW-NOISE, MULTIPLE-FUNCTION, X-BAND TRAVELING-WAVE TUBE.

Abstract

Work was done during the quarter on six items: the electron gun, focusing, the helix, the video section, tube VSWR, and the capsule. The overdrive performance in the linear section was improved by moving the attenuator toward the input, but further improvement in the limiter section is necessary. The use of tapered helices is contemplated. The helix design is capable of providing the necessary gain and bandwidth within the length specified for the tube. It was shown that the rf coaxial window assemblies can provide a VSWR of less than 1.3 to 1 from 7.0 to 11.0 Gc. The ppm focusing structure is adequate from both the beam-transmission and noise-figure aspects. The video section is mechanically sound but needs improvement in the processing of the dynodes.
